Hi Steve,

Looks like it will do the DVCPRO50 but not HD.

Best,

Hi Jan,

Yeah, this looks like a possible HDD solution for the SDX900, SPC700, or SPX800 - and a partial solution for the HVX. Hopefully by the time the HVX ships someone will develop a portable HDD with a big hard drive that will handle all of the formats, resolutions, and frame rates that the HVX shoots. I'm excited about the possibilities with the HVX for the broad range of television and video projects I do. I'm just hoping the accessories will be available to maximize the potential of the camera.

Thanks,

Jan:

What do you think is the bottleneck -- FireWire or the hard-disk speed? I'm guessing the hard drive -- laptop drives, which is what CitiDISK uses, tend to have slower rotational speeds to reduce heat build-up.

As a side note, I for one wish to apologize for being so hard on Panasonic for its P2 pricing. Although I am still convinced that it's overpriced, I think we should all gain some perspective. Grass Valley recently unveiled Venom FlashPak, a solid-state storage "film magazine" solution for the Viper FilmStream (PDF fact sheet here (http://www.thomsongrassvalley.com/products/cameras/venom/pdf/venom_fs.pdf)). What the brochure doesn't mention is price -- $59,000. So I guess expensive is a relative term.

Hi folks. Clicked on the link and it looks good but I couldn't find a price. Anybody know where to get one and at what cost? I googled and could only find reviews and MSRP for the DV version. They said it was cheaper than the Firestore but couldn't find out how much cheaper or where to get one. Anybody?

The site had a listed price of

$679.00 - 40gig
$729.00 - 60gig
$779.00 - 80gig
$849.00 - 100gig

Here's my question however? Keep in mind I'm not as technically astute as some people.

The HVX's p2 technology holds at the most, 8gig's. for about 2000 dollars.
Why the exceptionally high price? Is it because citidisk's storgage drives can't handle as much bumping etc...

I'm still not sure why P2 is the way of the future?

Hi Trevor,

Simply put, it's a question of the relatively high cost of solid state memory (no moving parts in a P2 card) vs. the relatively lower cost of hard disk recording (that is, somewhat delicate and fragile moving parts).

The advantages of P2 cards over hard drives are that solid state memory requires much less power to operate, has a tremendously high tolerance for g-shock, and is exceptionally quiet; all because there are no moving parts. Also, the internal array of SD flash memory cards that make up P2 memory are made with zero-fault tolerance, which means that they're 100% perfect. These are the primary reasons for the seemingly high cost, which is dropping all the time, of course.

Trevor Trombley

Ok, that explains some things.

On to my next question.

P2 cards are much like a mini harddrive. There's no compression, correct?

If so, cameras like the Thomson Viper filmstream produce image quality at 4:4:4. which is a direct transfer to the harddrive from the CCD's.

If that's the case wouldn't the HVX 200 be able to produce the same 4:4:4 image quality on the P2 cards. Although at this time I doubt 8 gigs is hardly enough storage space to hold something with that much information.

What's the skinny on this?

Chris Hurd

By definition, all digital video is compressed. Compression is a function of the video format, not the P2 card. The card itself is format-agnostic. It doesn't care what the video format is; it'll write what the camera tells it to write (as long as it's an H-series P2 card which can handle the throughput of high definition video).

The video formats which the HVX200 uses are DV and DVCPro, compressed at a 5:1 ratio and writing at 25 megabits per second; DVCPro 50, compressed at a 3.3:1 ratio and writing at 50 megabits per second; and DVCPro HD, compressed at a 6.7:1 ratio and writing at 100 megabits per second. The P2 cards bundled with the HVX can write any of these formats, but it's important to understand that yes, they are in fact compressed, otherwise it wouldn't be digital video.

Trevor Trombley

Hmmmm, that says a lot.

So when exactly does the camera do the compression? After the image has passed through the CCD's it can either be compressed to the DV, DVPRO, DVC pro 50, or the dvc pro HD formats?

So that means the viper Film stream. Or even the reel-stream andromeda. doesn't even go through the cameras compression functions? It skips the DV, DVPRO, DVPRO50, DVPRO HD formats and just gives you a raw 4:4:4 image?

Yep, the camera acquires the image via the CCD sensors and then processes it with internal firmware for specific enhancements: gain, edge enhancement, color correction, etc.. And then compresses it with the appropriate codec as it sends it on to the stream of video output.

So that means the viper Film stream. Or even the reel-stream andromeda. doesn't even go through the cameras compression functions? It skips the DV, DVPRO, DVPRO50, DVPRO HD formats and just gives you a raw 4:4:4 image?

Cameras like the Viper are a different type of animal. The viper acquires the image data and packages each frame into an uncompressed / raw image file and it continuously sends out individual raw frames. All processing of the Viper data is done in post. Other camera systems provide uncompressed image capture, like the Reel Stream Andromeda modification for the DVX100, which has it's own add-on firmware placed into the DVX that takes raw CCD data and streams it out over a USB2 port to be interpreted by a capture application on a host PC. The CCD in the DVX samples images at 4:4:4, but internal processing degrades the resolution and color information down by a great deal and then it is encoded in 25Mbps DV format, which is almost a total insult to the capabilities of the DVX100. Hence the reason the Reel Stream Andromeda project took off... It's an aftermarket hack job of an add-on that allows DVX100 owners the chance to grab that raw 4:4:4 CCD data before it's butchered by the DVX100's internal processing.

There are various levels of compression and types or formats of compression and not all of the top-of-the-line camera systems are uncompressed. Sony's HDCAM SR can be set to various compression levels and color space levels (up to 4:4:4) or uncompressed images up to a maximum output bandwidth of 800Mbps.

The HVX200 will almost definitely capture raw data at 4:4:4 and with the full pixel count of the internal CCD block (whatever that my actually be). However, it will be processed internally and sampled to the correct output resolution and color space for the selected format. DVCPro formats are 4:2:2 color vs. the 4:1:1 of DV or the 4:2:0 of HDV.

As Chris Hurd already said, P2 cards are format agnostic. If you plug one into a PCMCIA slot on your computer, it just looks like a standard PCMCIA storage device and you can put any type of file on it you wish.... The HVX camera won't understand what an excel spreadsheet or an MP3 file is, but you can put them there. You will be able to record DVCPro50 and DVCProHD-100 (as well as any other format you have access to) clips to the same card and access them from any computer that is equipped with a PC card slot. Technically, the maximum bandwidth for a P2 card is about 640Mbps (80 megabytes) per second. This is actually a limitation of the 32bit PCMCIA Type II Cardbus interface and not the RAM itself. It would actually be possible to construct a Type III P2 card which is a tandem Type II slot and interleave the data I/O and achive nearly double the throughput. However, don't hold your breath for that... Right now, there isn't any reason to do such a thing and 32bit PC cards will probably be obsolete by the time that reason does present itself. And don't get too excited over P2 bandwidth just yet, solid state SD memory (on which the P2 cards are based) is much slower to write to than it is to read from. So even if you can dub video off the card at 80MB/sec, chances are you can only write to the card at 15 to 25 MB/sec, which is still plenty fast enough for recording live DVCProHD streams, it's going to be a while before P2 or similar technology is ready to record HDCAM SR or similar types of data. I think we'll also have some grumpy HVX200 owners initially who will find that copying video back to a P2 card won't be much (if at all) faster than 1X speed for DVCProHD100.

Anyway, P2 is a huge leap forward and a chance to finally move away from tape (for certain types of productions). It won't be for everyone initially, but as capacities increase and prices drop, more and more people will convert and not just to P2 but other solid state alternatives and just like records, cassette tapes and soon movies on VHS, DV tape will become a thing of the past with only a select few using it. Panasonic's advertised prices on P2 cards are shocking, but they have several partners already licensed up so we can expect to see cheaper alternatives from common memory card makers to help bring those prices down. The third-party alternatives may not show up until next year, so early P2 adopters who buy with the HVX will probably have to pay through the nose, but it may be worth it. I know that if the HVX lives up to most of the hype and delivers decent HD image quality, I can probably pay for it and 2 or 3 P2 cards in just a few months, possibly with just one good paying gig, which may not be too hard if I'm the first one on the block in my town to own his own HD camera.

Wow, you certainly know your stuff Jeff.

To think that in ten years time we'll probably have consumer priced camcorders that can produce the same results as the Thomson Viper.

The possibilities will be endless.

That would be nice. :) I think the underlying electronics, sensors, etc... will all be there. A camera on the level of the Viper will probably be in reach of the "prosumer" or the moderatel budget indie filmmaker in the next 2 years or so in some form or another -- probably home-built solutions at first. However, there still remains the issue of quality lenses and accessories. Look at the Drake camera right now, it's one of the first that can qalify as something like this. Home-built, but still far from cheap. In 10 years, who knows... I have been in the high tech industry long enough to know it's foolish to speculate about such a far off time. But I can say for sure that when the time comes and cameras that rival the CineAlta or Viper are within reach of the savvy consumer or prosumer, just think of what may be available on the high-end. All things keep improving and camera companies aren't going to cut their throat and kill the high end... The high end just keeps improving along with everything else.

The possibilities will be endless.

Aren't they always? :)

Thanks for the reply to my post about the citidisk. Those prices are only slightly lower than the Focus but my question still remains, anybody seen the the street prices or where to get one? The reviews I found sure trumpeted the thing as a lower cost alternative to the Focus drives but if nobody has them for sale ... I couldn't even find them on B&H last I checked.

I am interested because moving to a tapeless acquisition would be fabulous but, although I am a very proud and happy Panny DVC 80 owner, I am still not convinced about this P2 "miracle" due to the high cost, proprietary and, at least at this time, limited capacity nature of the medium. And, as nice as Panny can be in terms of listening to their users, I can't see them offering a P2 camera that let you output to a third party's storage device since they would loss money on their proprietary system.

Now, however, if there was a way to marry a P2 to a firewire cable then kick out to a third party hard drive/storage device similar to the Focus or other makers, I would stand in line with everyone else for the new camera. But doesn't something like that already exist where you can plug in a PCMIA card into a notebook and then plug a firewire cable?

here are some firestore alternatives for sale online. they are slightly cheaper and support dvcpro. the only issue i see is their specified capture rate of 12MB. that's a little too close to 100mbps which doesn't include audio. might only be good for dvcpro50 and lower.

And yet, that's exactly what they're doing, since they recruited Focus to develop a DVCPRO-HD-compatible FireStore...

That may very well work. Needs to be tested to see.

I predict that there will be several alternatives to P2 with this camera. Right out of the box you will be able to record HD straight to a computer, or straight to a DVCPRO-HD tape deck, and never even have to see a P2 card. Others will develop other alternatives as well, that's a safe bet.

This is where a LOT of people seem to be getting confused and hung up on issues with P2.... First of all, there is *nothing* proprietary about P2. It is a standard PCMCIA Type II storage device and works in any standard Type II PC card slot. It is a very loosely licensed format and we can expect to see several third party P2 offerings. I'm guessing that PC storage cards will need to have a firmware flag identifying them as "P2 Compliant" in order for the HVX to use them, but that's minor.

As for price, yes P2 is expensive - especially with Panasonic's prices. However, take the price of P2 cards into consideration with the costs of your current workflow... They may make sense, or maybe not. I have shot nearly 300 DV tapes with my DVX100 since buying it and I have purchased DV tapes by quantities of 50 at a time for about $5.25 (Panny MQ tapes only in my DVX) per tape plus a little for shipping. Actually having purchased a full 300 tapes and I'll probably buy at least another 50 tapes before the HVX200 arrives, that adds up. I tend to archive all my video separately on DLT along with the rest of my project workflows as it is, so archiving DVCPro off of P2 won't cost me any more in the long run, it should just give me higher quality video to start with since most all my video is upconverted to fit my workflow before it lands on DLT anyway. So, I've already spent (in about 18 months) on tape what I would spend for an 8GB P2 card at the current full MSRP. I don't re-use tape with my DVX. Never even tried it. I learned with my previous cameras that after recording to a tape and then capturing from it a time or two, that if I try to erase and re-record to it, drop-outs became a lot more possible, but using a tape only once I think I experience a drop-out maybe once out of every 20 hours or so of video I shoot and it's probably even less frequent than that. Anyway, moving to P2 will provide a media that will cost no more within my workflow than DV tape over the period of about 3 years (considering two 8GB P2 cards), plus it will give me DVCPro50 and HD capability. So, is P2 really expensive?

For others who don't have a comprehensive backup solution in place already, there may be more of an impact in regards to cost and setting up a P2 workflow. However, I have to ask how everyone archives their work? Does nobody else actually archive their final projects or even in-progress versions of their stuff? I know a lot of people send their final back out to DV tape for archival (just add more DV tape costs into the mix). Most of what I do sees final delivery on DVD, and archiving back to DV tape makes little sense. Most of my internal workflow for CG and animation is already 1080p as I have been trying to future-proof my work as of the past 2 years. So, I keep my archives on DLT since most of my work has to be down-rez'd to DVD. When HD-DVD/BluRay come along, I can re-encode off my DLT master for the new format and already have HD content available. Having a camera that brings me closer to my internal working resolution with less upconverting is a no-brainer.

For someone who has been trapped entirely in a 720x480i miniDV world, stepping into an HVX200 and P2 workflow will be a big change. But this person will also be taking a step up. It's not that Panasonic has raised the price level of their next prosumer camera... They have actually lowered the price of entry into their professional line offering DV50 and the same HD formats used by the Varicam.

Craig, thanks for the links. They were just what I was looking for. I'll keep savin' my pennies.

Barry, if Firestore (or anyone else for that matter) will be releasing a more economical work around, I'll stand by my word and stand in line for the new Panny :) I may not have the computing prowess for HD but hopefully I will for up to DVCPRO50. Plus I am still trying to get a straight answer if Vegas can handle the Panny HD codec.

And Jeff; didn't mean to get you so upset buddy. I guess I am really very price sensitive since I am still trying to prove to my wife this will actually turn into something besides a very expensive indulgence at the moment. And I see I was mistakenly under the impression that P2 was a proprietary format but thank you for correcting me.

Hehe. No worries, I wasn't upset. I just type fast... Usually faster than I think and that gets me into trouble sometimes. But usually, before I know it, I have written a novel. :)

Anyway, every budget is different and this camera will make great sense for some, but not for others. I'm pretty sure that this is my next camera, but I will wait until it's here and I rent or borrow one to decide for sure. I think that this camera would be a logical upgrade for DVX100 users who could benefit from using DV50 and the ability to shoot HD (with reportedly better quality than the current HDV camcorders), all for a not too unrealistic price. But depending on your workload or type of work you do, it may be more realistic to stick with owning a cheaper camera and renting something even better than the HVX200 for special events/projects.

As for P2, it's not proprietary as we have already said, however it is a format that (as far as camcorders go) has only been adopted by Panasonic. We also still don't know the full details yet on whether or not any capable PC card storage device will work, or if the HVX200 will look for other firmware flags or settings that will force us to use actual P2 labeled cards. Either way, I wouldn't worry about P2 as a new format. PC card storage is standard enough that it shouldn't be a completely dead-end product and if Panasonic can get enough memory card makers to jump on the bandwagon, we'll have plenty of purchase options and lower prices as the format establishes itself.
