View Full Version : New GY-HM700 Camcorder
Brian Ladue February 12th, 2009, 09:56 PM Information has been very slow on this camera, I'd be very interested to see some footage or even some stills! Does the camera perform better than the 200/250s? Resolution wise? Low light performance? Tim, didn't you spend some time with the camera? Did you post some kind of review of the camera? The Panasonic camp instantly flooded the boards at the other forum with tonnes of info, footage, stills, etc.. The JVC camp seems pretty laid back about the new camera details. Where's the goods!?
Craig Seeman February 12th, 2009, 10:01 PM I posted the links below in the Sony XDCAM EX forum (after all this is an XDCAM EX camera even if it's not by Sony). I'm posting here since people might not have looked at the thread there.

I've seen the specs and photos of the camera already, what I'm referring to is hands on details...I'd like to hear some honest impressions of the camera. Tim said a few days ago that he was going to spend some time with the new cam. So, I'm wondering if he was able to record anything? if he could post some footage? or a still frame from some footage or something...
On another note does anyone know if JVC uses the same technique with the CCDs as they did before when the cameras (HD100s) started suffering from the split screen effect? And does anyone know what the native sensors size is? are they 960X540? 1280X720? I know they mentioned that H/V offset is used... so just wondering!?
Tim Dashwood February 12th, 2009, 11:15 PM I'm working on a review right now and I do have answers to most of the common questions. The phone's been ringing off the hook since I got back from NYC 24 hours ago so it is taking a bit of time. It should be uploaded by late tomorrow afternoon.
I also have footage I shot in most of the formats.
We actually have two HM700 threads going here so you may have missed some of the information in the other one. I think I'll merge them together into an über-thread.
Chris Hurd February 12th, 2009, 11:21 PM Information has been very slow on this camera... Tim, didn't you spend some time with the camera? Did you post some kind of review of the camera? Look, Brian, honestly I'm sorry that this isn't happening fast enough for you, but please realize that Tim just got his hands on it only yesterday, and there was a trip back home from New York since then. He's working up a written review as well as uploading some video clips, which I'll publish just as soon as they're ready. Tim isn't getting paid for this (although he should be), so let's all please respect how generous he's being with his time here.
To their credit, JVC was very patient and most accommodating for us, but it's their only sample, so our actual hands-on time was understandably quite limited. There's no question that Panasonic sets the standard by developing a close relationship and providing tremendous advance support and copious resources for their preferred online venue; no other manufacturer matches them in that regard. They're doing it right.
Meanwhile we're doing all we can with what we're given. If the pace is too slow for you then I'm sorry but you're on the wrong site. Honestly we will put out as much as we can, as fast as we're able. And I'm offering a full refund if the service isn't satisfying. Hope this helps,
Chris Hurd February 12th, 2009, 11:25 PM We actually have two HM700 threads going here... I think I'll merge them together into an über-thread.You know Tim, those can quickly become hard to follow. I think it's time for a new forum, with newer, more manageable discussions about specific HM700 topics...?
Brian Ladue February 12th, 2009, 11:41 PM Hey guys,
Sorry about sounding so rushy, I'm just a little anxious to see some details...and I didn't hear too much...I do appreciate the effort that goes into these things. My apologies, I look forward to your review.
Steve Mullen February 13th, 2009, 01:32 AM SDHC w/o SXS = .mov 19/25/35 flavors.
SDHC + SXS = .mov & .mp4 19/25/35 flavors.
Still a disappointment.
David, I'm not sure why the disappointment.
1) SDHC w/o SxS = .mov 19/25/35 flavors:
This option enables native (no transcode) real-time editing with FCP.
However, this option will likely not be limited to FCP. For the last several years I've been converting 30Mbps MPEG-2 FullHD from the JVC HD7 to MPEG-2 .mov files and they can be imported into other Apple applications and be edited in real-time. Some, if not most Windows, applications can import these files and edit them natively. Others may force a transcode to DNXHD.
I don't see any reason to be disappointed by these capabilities.
There are, however, open issues. Although it's EZ to talk about 25Mbps and 35Mbps files on SDHC cards that are "compatible" with XDCAM EX -- it may be an error to assume these cards duplicate the full functionality of "XDCAM EX on SxS" cards.
From working with camcorders that write to SDHC cards I've found:
a) Timecode resets to zero for each clip.
b) Files are limited to 4GB because these cards use FAT32. (That's why the next gen cards will use ExFAT.) Often camcorder firmware limits a single shot to a single file. Or, if their firmware does open new files as needed, the camcorder can't write them in a way that prevents data loss at the switch point. Here's a comment on the problem created by another camcorder, "Open the two files and you will notice 418 samples of audio missing just prior to the splice point and exactly two dropped frames just after the splice point."
The fact with the HM- series, can auto-cross card boundaries is a positive sign these camcorders will record information from long shots correctly.
Of course, it's also necessary that your NLE software can stitch long shot files together. Often the "next" file duplicates some of the frames in the "previous" file. Ideally, during import, your NLE SHOULD use timecode to create seamless video files. This is particularly important (and difficult) with long GOP formats.
2) SxS = .mp4 19/25/35 flavors:
This path gives you everything that XDCAM EX provides. Once you install the needed SxS driver, your computer can read SxS cards.
a) The Sony Browser can read files and will correctly stitch broken files together so they can be exported to ProRes 422 or DNXHD.
b) If your NLE supports XDCAM EX (.mp4) -- not XDCAM HD (.mxf) -- then you'll be able to skip using the sony Browser. However, when it comes to broken files, you'll need to confirm how your NLE handles these files. You also need to confirm if your NLE can natively edit these files. (If not, they will be auto-transcoded during import.)
And, if it can edit natively, can it do so in real-time?
3) SxS + SDHC = .mov 19/25/35 flavors on SDHC:
Frankly, I thought the SxS Media Recorder included a Sony encoder chip to force what was written to SxS cards to "be" XDCAM EX. Sony has always claimed its hardware encoder is far better than other MPEG-2 encoders. So it's possible previous posts are wrong and XDCAM EX can only be written to SxS. With the box attached, the SDHC cards are still written to from the JVC encoder.
>> Note the difference between an MPEG-2 file encoded by a JVC encoder that can be decoded by an XCAM EX decoder and a file encoded by a Sony XDCAM EX encoder. <<
It's also possible JVC has licensed the Sony encoder firmware that is unlocked by the SxS box. (The dongle concept.) Lastly, it's possible the box really does include a Sony encoder that feeds both set of slots.
However, I really would be surprised if Sony allowed anything fully equal to "XDCAM EX on SxS" to work with SDHC cards. This is why I expect there are SDHC limitations. (Were Sony to do so, it would leave itself open to why Sony doesn't use SDHC cards.)
David Parks February 13th, 2009, 08:41 AM Steve,
All great points. I'm disappointed because I can't afford the camera right now and the SXS extra cost for both the recorder and media is a bit disappointing. With cards and batteries it will take the price possibly over $10k.
I was under the early impresssion, based on the specs of the HM 100 that the HM 700 would be able to record ISO based media (.mp4) as JVC called it to regular SDHC cards. And I'm pretty much an Avid guy at heart.
So, I'm sure it will be a great camera, and I'm not saying it is overpriced, it is I'm just underbudgeted for now.
I will say that I'm now going to look at the Panasonic HPX 300 now while we are in the $10k range anyway. Avid already edits AVC Intra 100. After all, to me $10k is not just buying a camera, it is now a big investment and I need the best camera for the money.
Maybe in the fall, Cheeers.
John Markert February 13th, 2009, 10:23 AM I'm wondering if either the 100 or 700 will output downconverted SD. I still have clients that want DVCAM or DV, and I'd really like to feed it to a deck from the camcorder instead of trying to encode DV in an NLE. My little Canon HV20 will output to DV from HDV, which is very convenient at times.
Still hoping for 1/2" CCD's and AVC Intra from JVC.
Harry Pallenberg February 13th, 2009, 11:22 AM Steve says:
"From working with camcorders that write to SDHC cards I've found:

Say it aint so!!!!!!!! Anyone?
Matt San February 13th, 2009, 12:20 PM No reason it should be - its hardly an issue to implement if manufactures so desire. On my ex1 I can have options for how TC is recorded
I know its not HDSC before u all jump on my back.
Steven Lyons February 13th, 2009, 04:33 PM Steven, this really belongs in it's own thread. It's been discussed before, but I too have struggled with this. It's mpg2 artifacts that turn up when settings aren't optimized. Mpg2 itself tends to throw out information too soon in these areas, and it gets even uglier if you are then recompressing for dvd.
To get back on point, this is one reason to get very excited about the move to 35mps in the new generation cams. Seat of the pants tells me we won't be facing the bit starvation experienced at 720 60p with the 200 series, and 1080 30p will also be handled with aplomb.
The proof of the pudding will of course be in real life, and I hope to have the chance in the near future. Let me know if there are any specific things you'd like checked if/when I have this brief pre-release opportunity.
The "trade-in" was wild fantasy speculation, without any basis. Please let it die a natural death.
Thanks Sean,
glad I wasn't alone about noise levels and thanks for explanation, here in Australia, everyone thought I was over reacting, but previously to the 251 I had the 101 and it was virtually noiseless (I must have gotton a freak).
Anyway, I would love to hear about the sensitivity of the hm700 and of course, hopefully the lack of noise and mpeg2 artifacting.
This is a major reason I haven't taken my 251 too seriously and was really waiting for a scarlet..but if it is a different ball game with hm700 and 35mbs I am willing to take another look.
I have been looking very closely at convergent design and their flash xdr and more specifically the upcoming nano, this will have both hdmi input and output, plus hdsdi which will maintain a 4.2.2 signal at 50meg and 100meg, that should get rid of any mpeg2 artifacting.
Also convergent design have released some test files that I sent to matrox and they trialed them in cs4 with their latest axio le drivers and they worked fine.
Convergent design will also be implementing time lapse in the future units.
Sooo... this maybe a better option existing gyhd251e with nano, because I am assuming
the hm700 will still be recording in 4.2.0 color space.
Steve Mullen February 13th, 2009, 06:58 PM No reason it should be - its hardly an issue to implement if manufactures so desire. On my ex1 I can have options for how TC is recorded.
I suspect you are correct there's "no technical reason" why not -- as Sony has done it with their HVR-MRC1K CF recorder.
However, your EX1 uses SxS cards. So it's a marketing question of HOW to convince folks to spend the extra money for the SxS recorder.
If the identical QUALITY video is available without spending $1000 to $1500 -- what is the motivation to spend the extra money?
1) The ability to "have" XDCAM EX on SxS cards -- even though they cost far more?
2) Less "functionality" of the SDHC cards?
I'm not assuming anything is "missing" when using SDHC! I'm only cautioning that those who haven't used SDHC-based camcorders shouldn't ASSUME they work like solid-state tape. They can, but they don't.
Craig Seeman February 13th, 2009, 07:20 PM Steve Mullen et al,
SxS uses FAT32. There are no dropped frames or missing audio as spanned and split clips are joined. Using SDHC in the EX cameras have the same features as SxS except: slower transfer time, inability to overcrank to the full extent SxS can on Sony. No issues at all with time code reseting. Keep in mind JVC is a SONY partner as per IBC and I suspect JVC has implemented similar features.
Sony XDCAM Clip Transfer joins files for Sony EX. JVC records MOV natively.
It remains to be seen if overcrank works better on JVC SDHC cards. It seems the cards are certainly fast enough but on Sony EX they've "bottlenecked" the cards write speed. There are different methods of writing to SDHC and Sony may have chosen a protocol that limits the speed. It remains to be seen how JVC handles this.
BTW Sony is accessing the SDHC through an Express Card USB adaptor rather than PCIe used in SxS cards so JVC may handle this differently but none of this results in time code reset, dropped frames or lost audio joining clips. If anything JVC may even improve on this if they're using a protocol that avoids the "bottleneck."
Steve Mullen February 13th, 2009, 09:17 PM Using SDHC in the EX cameras have the same features as SxS except: slower transfer time, inability to overcrank to the full extent SxS can on Sony.
No one is saying "what" will be different. I suggest two capabilities. You have suggested a third.
Moreover, I opened two possibilities:
1) Less SDHC functionality -- which you have confirmed is what currently exists on the EX1/EX3.
AND/OR
2) The desire by a shooter to have recordings made on SxS simply because they feed into a well understood XDCAM EX workflow. It may be that even if quality and functionality are equal, some will spend the money to have "XDCAM EX SxS" recordings.
I'm only asking questions that we need answers to because they go directly to the issue of workflows.
Shaun Roemich February 13th, 2009, 10:23 PM It may be that even if quality and functionality are equal, some will spend the money to have "XDCAM EX SxS" recordings.
As a freelancer in addition to owning and operating my own video production "house", this is an important ability. Rather than trying to explain to clients what I can record to SDHC cards, I can offer them an industry standard format that they understand. Keep in mind that there is an XDCam EX "VTR" (DDR?) that outputs VIDEO, not just a file. For my broadcast clients, this is a field leveler.
Bo Smith February 14th, 2009, 12:51 AM 1) SDHC w/o SxS = .mov 19/25/35 flavors:

Thats all I needed to know. Mayonnaise jar I keep under my bed, prepare to hold part of my pay check for the next few months.

I agree -- the ability to deliver a format that has wide acceptance ON media that's well understood is certainly worth $1000. No hassles about "HDV" or "ProHD." Just say SxS.
And, no issues of Sony vs JVC either. :)
For other's of us -- there is no need to spend the money because all we want is high-quality footage at the lowest possible cost. In fact, for those of us that have been using other SDHC camcorders we are used to working with "clip-based" timecode.
Shaun Roemich February 14th, 2009, 09:04 AM And, no issues of Sony vs JVC either. :)
Which brings us back to the "old" days:
When you showed up with a Sony BVW507 dockable head, no one looked to see if your dockable recorder was Sony or Ampex. You said Betacam, they got Betacam, they edited Betacam. Unlike VHS-C: "well, it's VHS tape, but in a smaller case. You'll need an adaptor to play it... oh, and you can only get 40 minutes on it. Did I mention you need an adaptor? Actually, no, I don't have one you can borrow. I actually don't need it for my workflow and I'm not sure where to get one or which brand to suggest".
Andy Tejral February 14th, 2009, 09:19 AM no one looked to see if your dockable recorder was Sony or Ampex.
While I certainly haven't made an exhaustive study, all the Ampex Beta equipment I've seen just had the Sony label pried off and Ampex written in in crayon. Well, maybe not but it was clearly a Sony product.
Shaun Roemich February 14th, 2009, 09:35 AM Really? The Ampex stuff I'm used to seeing extended a good 2 inches over top of the body, whereas the Sony branded stuff was nice and sleek, because THAT makes a difference in image quality... <laughs>
I'd be interested to know if you get a DEFINITIVE answer on the Ampex branded stuff...
Andy Tejral February 14th, 2009, 10:21 AM I'd be interested to know if you get a DEFINITIVE answer on the Ampex branded stuff...
Still not definitive but, from wikipedia...
"Ampex, Thomson SA and Philips each sold rebranded OEM versions of some of the Sony VTRs and Camcorders at various times in the 1980s and 1990s. Other than nameplates, these models were identical to the Sony models."
But yes, JVC cameras were largely compatible with Sony decks--though I think they needed an adapter--JVC decks slapped right on without. Same with Ikegami, I believe.
Simon Denny February 15th, 2009, 03:39 AM Has anyone had a play with this camera yet?
Chris Hurd February 15th, 2009, 12:18 PM Yes. See http://www.dvinfo.net/conf/1010873-post140.html earlier in this thread.
We'll put up a review shortly.
Claude Mangold February 15th, 2009, 05:35 PM Andy is definitely right. It's just re-badged.
We have an Ampex CVR22 standing around, but the operating manual says "Sony BVW 22P"
And our BVW 75P has a manual saying "Ampex CVR75"
Looking forward to the review of the JVC 700 !
Clint Harmon February 15th, 2009, 05:38 PM The HM700 looks to be causing quite a stir.
I have not seen anyone on this thread mention anything about importing to Premiere on a windows based NLE. Does anyone have any input on this?
The JVC press release and other forums I have read online refer to using Apple and FCP. One article even started "One must be married to FCP...to use the HM700"
Did JVC alienate us non apple people?
Tim Dashwood February 15th, 2009, 05:42 PM Does anyone know what the second file format extension is when using the HM100 or HM700? ...What does "ISO based" mean? On the HM700 page it states that it can record to XDCAM EX compatible .mp4 files only with the optional SxS recorder. What is the extension going to be when shooting to the SDHC cards?
The two extensions available are .MP4 and .MOV. These of course are just containers for the XDCAM EX codec which is the only codec the HM700 records in. You can write XDCAM EX in the .MOV container to SDHC cards on a out-of-the-box HM700. If you want to write .MP4 you will need to add the KA-MR100 SxS module that unlocks the ability to record .MP4 to SDHC or SxS.
Wow. Sorry JVC, but it looks like someone dropped the ball on this one. ONLY native FCP recording without an extra $1500? Would it have really killed you to have added another format, such as MXF? Wouldn't that have opened up the horizons a little instead of limiting them?
What I really don't understand is why the smaller camera has this option, but the larger one does not?
It isn't really native to FCP since you can download the free open-source Perian XDCAM EX codec (http://blog.lib.umn.edu/mcfa0086/discretecosine/164630.html) for Quicktime and play these files on any mac. For Windows Vista or XP you can use XD Decode (http://www.calibratedsoftware.com/QXD.asp) codec for Quicktime to work with XDCAM EX .MOV files. I still have to test this myself but the EX1/3 camp seems to give this software a thumbs up.
BTW the "MXF" indication on the engineering sample of the HM100 will likely change since the recorded container was still MP4.
...what is the extension going to be if we shoot in 25mb or 19mb mode? Is it still .mp4 or something else? XDCAM EX is used no matter what the bitrate. However the firewire port on the camera will output a HDV stream if you are using 19Mbps for 720p or 25Mbps for 1080i.
Yes PC's can use QuickTime - HOWEVER: Those of us who use Avid know quite well that it cannot import timecode from quicktime files. xml files are also included for each .MOV clip that contains all of the meta data including timecode. Presumably you can just import these xml files and relink them to the converted media.
The fact that no one from JVC has chimed in yet shows me that it looks like our assumptions are right: if you want to record anything with the Sony codec, you have to buy the Sony hardware. That doesn't do me any good and at that point I'd rather buy the Sony EX Camera, it looks cheaper at that point, plus you can use the SD workaround and shoot just as cheaply.XDCAM EX aside, Sony's EX series doesn't really have any ergonomic similarities to the HM700 or the lens selection, but they do use 1/2" chips instead of 1/3". There are pros and cons to everything. JVC representatives will chime in when Chris or I send an email request for clarification but they don't sit around all day watching our forum!
...mxf is used by Avid, Adobe Premiere, After Effects, Canopus Edius and others as the file format for editing the Sony MPEG 2 codecs, among other codecs. So it isn't just Avid that they're possibly leaving out. JVC licensed XDCAM EX from Sony which uses the MP4 container. XDCAM HD uses MXF. I'm sure there is an easy way to move from one container to another, I just don't know specifically. Avid MC3 does support XDCAM EX as does Premiere Pro CS4.
The Sony EX cameras write an .mp4 file inside a proprietary folder structure. It's an mpeg2 codec, that writes to an mp4 container. Sony Vegas will NOT import that .mp4 file and it needs a rewrap to MXF. Thus it appears to me that NONE of these NLEs understand the XDCamEX codec and ALL need a rewrap.
...ProRes QT files apparently will drop into anything, though it is unknown to me if it will drop in with timecode in NLEs other than Avid.
The whole thing is a mess.It certainly is confusing but the benefit of Sony's success with the EX series cameras is that it is in the NLE manufacturers' best interest to support XDCAM EX.
Anyone know how many minutes a 32GB card will hold of the highest setting?
It should be around 2 hours on a 32GB SDHC card using 35Mbps. It is a Variable Bit Rate codec so that time may extend if the material is "simple."
However, according to Tim Dashwoods first post here:
http://www.dvinfo.net/conf/jvc-pro-hd-acquisition-systems/141123-specs-new-gy-hm100-prohd-camcorder.html
The GY-HM100 will record 19, 25 and 35Mbps to SDHC cards.
This also includes the ProHD formats and 1440X1080 and 1920x1080 interlaced formats.
Wouldn't it be reasonable to think the HM700 would record these all to SDHC, even though the SXS recorder may add additional options? It would be reasonable to think that because there are no technical limitations. It seems to me that this is simply a condition of JVC's XDCAM EX licensing agreement with Sony (who also just happen to manufacture and sell SxS media.)
I do find it interesting that the HM100 can record to SDHC in all flavors without the SXS. It makes me wonder if Sony is twisting JVC's arm to sell SXS.Occam's Razor at work! That would seem to be the most logical explanation.
But this brochure is even more confusing. If you look at the boxed table on page 3 under 35 Mbits, there is an asterik by 1440x1080 60i and 50i that references the note ".mov only"
Which totally contradicts the specifications page that listed 1920x1080i as .mov only and no reference by 1440x1080.
So it is a clear as mud...
I think you've discovered a typo in the spec page. The 1440x1080 spec is there to provide backwards compatibility with HDV (via firewire.) I don't think it is officially part of the XDCAM EX spec so that is why it is Quicktime only.
EX1 does 16GB per hour (@ 35Mbps.)And so will the HM100/700.
Thanks, Chris, for clearing that up. So, unless we pony up for the SxS adapter, we're stuck with ProRes QuickTime files.Not ProRes. XDCAM EX codec is used whether the SxS adapter is attached or not.
...It would seem then that the JVC camera offers what the Sony cameras do, _plus_ the Quicktime wrapper option.Exactly.
Information has been very slow on this camera, I'd be very interested to see some footage or even some stills! ...Tim, didn't you spend some time with the camera? Did you post some kind of review of the camera? The Panasonic camp instantly flooded the boards at the other forum with tonnes of info, footage, stills, etc.. The JVC camp seems pretty laid back about the new camera details. Where's the goods!?
...I've seen the specs and photos of the camera already, what I'm referring to is hands on details...I'd like to hear some honest impressions of the camera. We're not laid back about our press coverage. In fact I can guarantee no other publication will have as in-depth coverage of the HM700 as we will or asks the questions we do. Unfortunately analyzing footage, making sense of our many photos of the internal menus, testing the formats across platforms, waiting for technical confirmation from JVC and writing an in-depth review spanning 5 pages (without the photos) takes a few days. Chris is in the process of formatting my article for the website, inserting movie files and pics and uploading. Trust me, you won't be disappointed.
On another note does anyone know if JVC uses the same technique with the CCDs as they did before when the cameras (HD100s) started suffering from the split screen effect? And does anyone know what the native sensors size is? are they 960X540? 1280X720? I know they mentioned that H/V offset is used... so just wondering!?I've been told that the CCDs are once again 1280x720 but the red channel is offset horizontally and the blue channel is offset vertically allowing more than 900 TV lines of resolution (full 1080P.) We'll have source footage available shortly.
I'm wondering if either the 100 or 700 will output downconverted SD. I still have clients that want DVCAM or DV, and I'd really like to feed it to a deck from the camcorder instead of trying to encode DV in an NLE. My little Canon HV20 will output to DV from HDV, which is very convenient at times.
The HM700 will downconvert to DV NTSC or PAL via firewire (something the JVC HDXXX cameras are not capable of doing.)
Still hoping for 1/2" CCD's and AVC Intra from JVC.
Keep hoping. 1/3" is well established with JVC and Mpeg2 isn't going anywhere anytime soon.
Steve says:
"From working with camcorders that write to SDHC cards I've found:
a) Timecode resets to zero for each clip."
Say it aint so!!!!!!!! Anyone?The HM700 (and HM100) have full control over the TC generator. You can preset the TC and record in FREE RUN, REC RUN or REGEN just like a tape based system. The other neat thing about the HM700 is that you can record in Continuous Clip mode which will append each new clip to the last giving you one big clip at the end of the day (split in 4GB chunks for Fat32.)

The JVC press release and other forums I have read online refer to using Apple and FCP. One article even started "One must be married to FCP...to use the HM700"
Did JVC alienate us non apple people?
Not at all. That is simply confusion based on JVC's press materials that tend to "beat around the bush" with regards to the format.
It's been discussed quite a bit already in this thread but here are the basics again (just so everyone gets it.)
The codec used with the HM700 is XDCAM EX at bit rates up to 35Mbps.
The wrapper/container used on a new "out-of-the-box" HM700 is Quicktime .MOV and it can be written to SDHC cards.
The addition of the KA-MR100 SxS module will allow the ability to write XDCAM EX to SxS cards in the MP4 container, but will also unlock the ability to write XDCAM EX to SDHC cards in the MP4 container.
Premiere Pro CS4 natively supports XDCAM EX MP4 files. I downloaded the trial and imported them easily. It seems that XD Decode (http://www.calibratedsoftware.com/QXD.asp) will allow you to import XDCAM EX .MOV files on a PC but I am in the process of testing this.
On the Mac you don't even really need FCP installed if you download and install the open-source XDCAM EX codec (http://blog.lib.umn.edu/mcfa0086/discretecosine/164630.html). This even works with Sony's XDCAM Transfer software.
Joe Carney February 15th, 2009, 06:10 PM is the HD SDI output 10bit 4:2:2 or still 8bit?
Tim Dashwood February 15th, 2009, 06:32 PM is the HD SDI output 10bit 4:2:2 or still 8bit?
Good question Joe. I can't find any info on that. When I get a production model in my hands I'll have to shoot a smooth grad chart and see if there are any differences when capturing at 8bit or 10bit.
Steve Mullen February 15th, 2009, 09:06 PM Additions to the "basic" clarifications:
The codec used with the HM700 is XDCAM EX at bit rates up to 35Mbps.
The wrapper/container used on a new "out-of-the-box" HM700 is Quicktime .MOV and it can be written to SDHC cards.
Within the .MOV wrapper will be long-GOP MPEG-2 with PCM (not MP2) audio. This can be imported and edited natively in real-time by FCP, and from my experience other Apple NLEs should be able to do the same.
Since some Windows NLE will also import .MOV and can edit MPEG-2 natively, these NLEs should also be able to edit the .MOV files.
Media Composer likewise should be able to "import" files, but will transcode to DNxHD.
I'm saying "should" because there are a whole flock of frame-sizes, frame-rates, etc. that need to be checked one-by-one.
1440x1080i will only be available via .MOV.
And, it appears that there will be no functional difference (i.e., timecode) between SDHC and SxS cards, which makes the basic 700 -- and 100 -- really good buys.
The addition of the KA-MR100 SxS module will allow the ability to write XDCAM EX to SxS cards in the .MP4 container, but will also unlock the ability to write XDCAM EX to SDHC cards in the .MP4 container.
You gain access to the entire XDCAM EX workflow from a JVC camcorder.
You can use all the tools (Sony Clip Browser, etc.) that are available for XDCAM EX.
You can use the current XDCAM EX workflows available for most NLEs. Just don't confuse the XDCAM HD (.mxf on optical disc) with XDCAM EX (.mp4 on cards).
If your NLE does not support XDCAM EX, you can use the Sony Clip Browser to convert files to another format.
===========
Still an open question:
The word "codec" has multiple meanings. Of course, we know both the .MOV and .MP4 MPEG-2 data are compatible with an XDCAM EX DEcoder. That's the definition of a format.
However, many different encoders -- of widely differing quality -- can be used to generate a compatible data stream.
Therefore, one also needs to know -- are different ENcoders (or different firmware) used for writing .MOV files when the SxS Media Recorder is not present and when the Media Recorder is present and the 700 writes XDCAM EX to SDHC and/or SxS.
Tim Dashwood February 15th, 2009, 09:46 PM I've attached a frame grab of the file structure on the SDHC card that contains both Quicktime wrapped and MP4 wrapped clips. As you can see the MP4 clips are in folders for each clip and follow the same structure at the EX1/EX3.
The Quicktime .MOV files are all contained in one folder (even though each of my samples are of different frame rates or dimensions) and xml files with the pertinent metadata are located in a folder beside it.
You may also notice that all the files have "DASH" as their prefix. The HM700 has the ability to make a 4 character prefix for the files. "CAM1" would have probably been ideal but I used "DASH" just so I knew those were my files.
Clips 1 through 4 were recorded as Quicktime. I then switched the camera to MP4 mode recorded clips 5 and 6, and then switched back to .MOV for clip 7.
I've also attached frame grabs from Media 100 Producer and Adobe Premiere Pro CS4 (Mac) showing that the XDCAM EX Quicktimes can be imported on a basic Mac system that doesn't have FCP installed, but does have the free open-source XDCAM codec (http://blog.lib.umn.edu/mcfa0086/discretecosine/164630.html) installed. Media 100 doesn't seem to support the codec natively but instead prefers to transcode it into its own codec. Premiere Pro does seem to support it natively on the Mac as a .mov.
I installed XD Decoder (http://www.calibratedsoftware.com/QXD.asp) on Windows XP and was able to open the Quicktimes in Quicktime player without issue. I assume this means that any Windows application that supports Quicktime will work with these files but I'm downloading the Premiere Pro CS4 demo for XP now and will have some more answers soon.
Harry Pallenberg February 15th, 2009, 10:18 PM Thanks for the large post of answers a page or so ago.. and for the file info above... looks like we're getting closer to some grabs, reviews, footage..
Thanks for all your hard work.
Tim Dashwood February 15th, 2009, 11:21 PM I installed XD Decoder (http://www.calibratedsoftware.com/QXD.asp) on Windows XP and was able to open the Quicktimes in Quicktime player without issue. I assume this means that any Windows application that supports Quicktime will work with these files but I'm downloading the Premiere Pro CS4 demo for XP now and will have some more answers soon.
Success! I was able to import the Quicktime files directly into Premiere Pro CS4 on Windows XP without the need to transcode. The properties of the imported .mov clips properly report XDCAM EX as the codec and all of the sizes and frame rates seem to work. (The gray bars are the watermarking done by the trial version of XD Decoder.)
Steve Mullen February 16th, 2009, 12:49 AM "Within the .MOV wrapper will be long-GOP MPEG-2 with PCM (not MP2) audio. ... and from my experience other Apple NLEs should be able to do the same."
Confirmed -- .MOV files can be imported and edited as native MPEG-2/PCM in real-time by iMovie 09 and can be imported into OS X Media Composer. MC will transcode to DNxHD.
PS: Note that Media 100 still will not directly edit 720p30. If you import 720p30 -- it will convert it to 720p60. While this will work, the transcoded file will be twice as large.
Tim Dashwood February 16th, 2009, 01:12 AM ".MOV files can be imported and edited as native MPEG-2/PCM in real-time by iMovie 09 iMovie08 wouldn't accept the XDCAM EX Quicktimes. I guess I need to go pickup iLife 09!
BTW iDVD08 accepts the XDCAM EX Quicktimes just fine.
David Heath February 16th, 2009, 04:20 AM I've been told that the CCDs are once again 1280x720 but the red channel is offset horizontally and the blue channel is offset vertically allowing more than 900 TV lines of resolution (full 1080P.) We'll have source footage available shortly.
Interesting, though I think that should really have the caveat "...more than 900 TV lines of luminance resolution ...". With a 4:2:0 recording system, it shouldn't make much practical difference, except maybe for more colour aliasing than a non-pixel shift system.

Tim, 08 restricted import formats more than does 09. I'm shooting 720p30 H.264/AVC (not AVCHD) with a DSLR-type camera whose files QT played fine, but 08 wouldn't import. With 09 they import and I can edit them natively -- no convert to AIC.
No luck with the MPEG-2/PCM file with: Vegas 8 Pro, Studio 11, Avid Xpress Pro, and Canopus 4. The PCM audio imported fine, however. Don't yet know if it's the lack of an MPEG-2 codec or the 35Mbps data-rate. Expect a download of "XDCAM EX" codecs will be the solution.
Uli Mors February 16th, 2009, 07:52 AM Tim, just to understand you right:
In your example (screenshots of the media) there were those typical SxS folders (Dash0005) - did I understand you right that these folders (ex1 like) are only generated when KA-mr100 installed?
Or wayaround: out of the box the hm700 can only write quicktime movs, correct?
Thanks
Uli
Brian Ladue February 16th, 2009, 12:34 PM The HM700 (and HM100) have full control over the TC generator. You can preset the TC and record in FREE RUN, REC RUN or REGEN just like a tape based system. The other neat thing about the HM700 is that you can record in Continuous Clip mode which will append each new clip to the last giving you one big clip at the end of the day (split in 4GB chunks for Fat32.)
So, are you saying that the timecode will not restart for each clip? I remember reading someones post earlier and they said that cameras that record to SDHC cards restart timecode for each clip? maybe i read that wrong. Can you clarify? Thanks

Yes you are correct.

I remember reading someones post earlier and they said that cameras that record to SDHC cards restart timecode for each clip? maybe i read that wrong. Can you clarify? ThanksAs far as I can tell it won't reset to 00:00:00:00 in REC mode as long as you stay in that particular shooting mode (720 or 1080.) In my test clips the timecode I preset to 01:00:00:00 continued generating from clip to clip until I switched from 720p to 1080p, and then it reset to 00:00:00:00. Keep in mind this is a pre-release one-of-a-kind engineering sample so everything is subject to change by the time the camera ships.
Jeffrey Butler February 16th, 2009, 09:28 PM Well, this thread has been a lot of fun, having just gotten back around to read it all.
I for one, need little more info to want one of each, the 700 + 100. The 700 will even prevent me from hopping ship to a 5D. Seriously. I know the application is different, but having just shot for a month last September with 2 breadloaf EX1's, I was very ready to find some better image quality...looks like I just did. And, I can keep with the form that I've come to love.
So I've got an HD250 in excellent condition w/ the 17x Fujinon lens upgrade....I think I need to talk to Scott Cantrell or Terri Nixon.
Maybe you really want a 250? =)
Jeffrey Butler February 16th, 2009, 09:31 PM And thanks for the major effort you put into simply discussing this latest round of products, Tim and Chris...
Joe Carney February 17th, 2009, 12:44 PM I hope the low light capability on these are good. I'm in the process of specking out new HD cameras' for my church and these could be an affordable alternative to the EX3s'. They want to move to an Apple/FCP based editing system anyway. For my Church, 8bit 4:2:2 is perfectly great, I need 10bit for my upcoming feature this spring.
Brian Tori February 17th, 2009, 01:56 PM Tim,
You stated that you were able to import .mov files into Premiere CS4 on Windows XP without issue. My question is, do you have to use XD Decoder to do this, or, will Premiere import these regardless without having to render? Is XD Decoder only necessary if you want to playback files using Quicktime player?
David Johns February 17th, 2009, 03:29 PM .... it was on display at the Broadcast Video Expo in Earl's Court, London today. Apparently the only one in existence, it was flown over from America on Friday. I didn't get the chance to do any serious testing with it but it was 'live' on the stand, plugged into a large monitor and available for anyone to pick up, sling onto a shoulder and play with.
The sensors, they tell me, are indeed 1280x720, scaled up to 'full' HD. It was heavier than I expected, oddly but entirely comfortable on the shoulder, seems to be very similar to their existing tape-based models so far as I could tell.
There's been a bit of flip-flopping within JVC about what lens it will ship with over here and at what price. The sales people on the stand say the latest is that it'll come as standard with a 16x Fujinon lens that's used on their current 200-series units - and will have a lower-than-I-expected street price of around £5,000 + VAT (sales tax).
For a few hundred pounds more (£6,300 list price, ie less than that on the street), a wider Canon 14x lens will be available. Interestingly, the SxS option module was quoted as only 500 euros; that's about £450 at current exchange rates. That may be only the case if bought as a bundle with the camera though, I wasn't quite sure on that point.
The LCD screen is (relatively) vast and so far as I could tell in the less than ideal conditions of a trade show, quite clear and crisp. Menus were easy to navigate with the big silver button on the side of the camera and did't involve many button presses. Apparently the final version will have a customisable "favourites" menu of sub-options that can be clicked through to very quickly though it wasn't available on this engineering preview model.
The JVC rep I was chatting to has promised to sort out a loan unit for me as soon as the production models hit the shelves in March (it was going to be at NAB but the've brought the date forward)
Regards
Dave
Dennis Stevens February 23rd, 2009, 12:12 PM Sorry about the newbie (but basic) question:
If I record at 1080p24 to the SDHC cards, how long can I record to say a 16gb card? A few minutes? An hour?
I've never used the SDHC, but I love my JVC HD100, but the HM700 is very tempting. I'm sooooo ready to never use tape again.
Shaun Roemich February 23rd, 2009, 12:25 PM According to my calculations, at 35mbps you should get 1h5m out of a 16GB card. 1h30m at 25mbps.
