Been away on vacation for a couple of weeks but just wanted to give an update: I have been having an email dialogue (of sorts at least) with Canon USA Sr. VP and General Manager Yuichi Ishizuka on the issue. I'll let you know what his response is hopefully by the end of the week.

Thanks for keeping us posted. We are behind you.

Thanks for doing this. :)

Please make sure to mention that people are buying the camera for this feature. When compared to the Sony competitor, the HV20 has better low light capability, thanks chiefly to the 24p mode. Reviews and Canon itself tout this feature. They need to make it so we can actually use it without jumping through overly-laborious hoops!

Thanks Peter for taking the time :)

I agree, while you have their ear ask exactly how the average guy is supposed to edit the much touted 24P footage... otherwise it's really not much of a feature... just marketing hype.

It's great that it's there, and I'm sure sooner or later there will be patches for the major NLEs, but if they could have made it easier to edit, sure would have been nice. Since apparently "flags" would do this, it's a glaring omission.

I've shot some 24P, but other committments have prevented my trying to download all the software for the free windows workflow and try it out... I used to shoot 30F with an old Panasonic and really liked that footage - no stinkin jaggies/zippers/whatever you want to call 'em to deal with as each frame was a complete progressive "picture", not half a scan. I would love to be able to get the same thing with this cam, and that's one of the reasons I bought it...

I'm speculating to some degree, but it would seem like progressive should help eliminate some of the infamous "rolling shutter" as well... sort of frustrating it's not more easily accessable!

Saaaaaaalude!

Me and looks like a bunch others appreciate you staying with this.

It would be great to get it taken care of during capture, all this sending out and getting back huge AIC or ProRess files really isn't the best/most efficient use of my time/resources.

Keep at it, Peter!

best,

Last week I also emailed Canon about the lack of pulldown flags. Here's tech support's response:

"In the USA as well as many other countries the Canon HV20 offers a
selectable shooting mode which uses true 24 Frame progressive shooting
to give your video a more cinematic look. These frames of video are
recorded onto the tape or output via the HDMI, IEEE1394 or composite
terminals by adding a "2:3 pull-down" to convert the 24 Frames in 30
Frames to be compatible with Televisions and monitors. This is the same
industry standard system used to show "Hollywood" movies on Television.
Most consumer software packages are capable of editing this video in the
same way as any other DV or HDV video. However some high end customers
have requested the ability to import the video into professional video
editing suites and applying a 2:3 pulldown to the footage which allows
the individual 24 Frames to be extracted.

In HDV (one of the many recording formats of HD video), Canon uses 2
systems of recording 24 Frame video. In our Pro 3 CCD products when you
are using the 24 Frame mode, we record the 24 Frames directly to HDV
tape (there is no 2:3 pulldown). This means that when you import the
footage to an editing system, the footage is already 24 Frames and can
be placed directly on a 24 Frame timeline. This is true 24P recording.
The other system is applies a 2:3 pulldown to the 24F video and records
it as 30 Frame on the HDV tape. We use this system in our consumer class
camcorders.

Since the Canon HV20 is a consumer class of camcorder it does not
include a feature to record 24 Frame video directly to HDV tape. By not
including this feature, frame extraction is somewhat more difficult,
requiring that the editor manually identify the 2:3 pulldown, then the
editing program can extract the 24 Frame video. This process varies from
one editing program to the other and may not be available on all
programs.
These requests are being noted and forwarded on to our product
development department to determine the feasibility to add this feature
to the HV20 or a future consumer model.

However, at this time, there are no plans to modify the HV20's feature
set in any way."

that's sort of discouraging...
i got the exact same reply, verbatim.

we seem to have frustrated them to the point of developing a form letter for us and our demands...

What's wrong with a form letter? Wouldn't you rather have a situation where everyone receives the *same* reply, as opposed to each person getting a different explanation? I mean seriously, wouldn't that be a heck of a lot worse, if they were saying different things to different people -- can you imagine the confusion and frustration created if the reply was *not* the same for each person?

Well Canon didn't exactly anwered our question, did they?
Didn't Peter just request adding the flag information about pulldown so that inverse telecine can be done a bit easier? I don't think any of us here have expected them to add that "24 frame mode" to HV20.

I think it's neat that the form letter refers to us as high-end customers. :)

I agree Chris, a form letter in response to our Emails is a good thing, it's good to actually get a response from one of these companies. Looks like I'll need to keep using AE to remove the pull-down which isn't a huge deal, just one more step.

Euisung! Holy cow! Glad to see you posting here, so are you an HV20 owner too? And yeah, we aren't asking for 24f as the form letter seems to suggest, though if they wanted to add it I don't think anyone would complain.

I talked to the (only) two Canon video reps in the US about the problem at a Multimedia workshop last week in Portland. The short answer: It's not our problem, we will not change anything on this camera or it's firmware...

No news yet... but hold on to the idea of a form letter. I think we may need to create one of our own. ;-)

Hi Wes, great to see you here too. (oh the good thing about using real names in the forum :)

Yep I'm the proud owner of HV20. This cam is such a joy. Too bad I don't have enough time to use it as much as I'd like to. I'll check out the clips of your site and learn a thing or two about this camera.

They need to be hit in the pocketbook or they won't do anything. Of course they'll say it's not their problem as long as the camera is selling.

If we post reviews to Amazon, et al (I bought my HV20 there so I can post a review; I don't know if that's a requirement) warning people that they can *shoot* 24p but good luck actually viewing 24p with any kind of ease, other than straight off the tape into a HDTV, perhaps word will get around about this problem and Canon will be more motivated.

It is a good company that keeps everyone stating the "official" line on any given issue. It's at the VP and GM level where possibilities are entertained. If a simple, cost effective improvement is possible that substanially improves on the botom line and extends the product lifecycle, our request will be granted. On the other hand, if it is perceived that this improvement causes loss of sales to higher-end equipment...

Just for the record, my friends at Canon USA, I bought my HV20 at the same time as my XH A1:-)

Cineform's Aspect HD HDLink add on for Adobe premier makes pull down pretty painless. It performs the pull down as it captures the video in m2t format on your computer. By the time it's done capturing it's in 24p and ready to go. Just import the video into a 24p work space and start editing. I tried it with a little 15 min video I shot at a park and it worked really well. Just plug the camera in, fire up HDLink tell it to pull down, and hit capture. When I was done capturing I checked the properties on the captured video it was at 23.97 fps so I'm pretty sure it's that easy.

Not to be busting balls on this issue, but I would be cautious as to what you guys are asking for....

why, because the HV20 is a " consumer " cam, that Canon put a not so consumer function, 24P.

When Canon puts that function on a " pro " cam they know that the pro has the knowledge and equipment/software to handle the function and without having to worry about folks writting in for added functionality...

So, if too many folks raise cane to get more functionality out of a consumer cam because some folks' choice of editor doesnt work friendly with 24P, Canon will just drop the function on future consumer products.


Don't think they'd do that??? Well they did it with their still Camera's...

Canon dropped RAW from all of their consumer P/S still cameras, with much
angwish amoungst it many supporters.... why, because Grandma wasn't using it and many folks just didn't have the software to handle RAW photos....

Canon did put in 24P functionality for the HV20... it works great, looks great and all anybody needs to utilize the functionality is to use the correct workflow... and Canon isn't going to lead anyone down that path... they know the Pro shops have the hardware/software, they also know the consumer just needs to step up to the plate and adjust their workflow to utilize the function...

Presently there seem to be two very capable work flows, and they support both Windows and MAC....

The easy way is Cineform, it don't get any easier than this and then there is the free software effort that seems to work just fine after you get all the components in place....

I just hope that Canon doesn't decide to par down any functions that may be on the Engineers table for the HV30, due to folks not accepting workflows where they may have to shell out more $$ or work a little harder in the free workflow arena.

I agree with what ray bell said dont stir the pot up to much they gave you great cam that you can get for less then a 1,000 bucks and for 200 or so more you add on the cineform and get the 24p pull down so for about 1200 added in with audio adapter to hand xlr inputs about 1,500 buck you got pretty good HDV camera with great image , but it woul be nice the HV30 had the flags and gain control and one xlr input :)

peace n luv


Martin

I concur, the 24P mode is very nice, but its also not an absolute necessity to get great video from the camera.. Standard mode works just fine for most shooting as I see it. If there is something that you will capture that will benefit from the 24P mode, then you'll have to get the software needed to be able to effectively edit that video..

Canon provided a great feature in a consumer format camera, if you want to manage 24P without the software, get a higher end camera, whose cost will probably be more than just buying the needed software to manage the video from the HV20.

I think that part of it boils down to how 24p is presented by Canon though. They are touting 24p with this camera, which is great. What they aren't telling you is that it's extra $$$ to work with that format because they do not provide a means by which it can be easily worked with. The fact it's there in a format that pretty much none of the major NLE's can deal with natively is a bit of an eye raiser to me. Canon says you can shoot 24p which is correct, but where do they say anything about what you have to do to actually "work" with 24p? Nowhere that I've found. No list of available applications to support their implementation of it.

It's just a tad misleading on Canons part to push the 24p thing so highly and yet not to have a way to offer folks the ability to do anything with it properly.

--Steve

I agree with what you are saying Steve. That was my gripe from the start...that their advertising this as true 24P was kind of misleading. I did however take another look at their demo footage for the HV20, frame by frame and to my suprise the pulldown was not removed. If you look at some of the motion where the woman goes to take a seat at the bar it (ghosting/blending) jumps right out at you. I was wondering why the video did not have much movement overall ...like their upper end cams demos.

For those concerned about Canon dropping the 24P because of user complaints...I highly doubt it. What Canon did was raise the bar for other brands to catch up. I suspect within the next year or so other manufacturers will start to introduce this feature (and then some) in their brands. If they (Canon) were to pull it out of the HV30 then it would be their loss (R U Listening Panasonic?)

As an enthusiast/hobbyist, I am perfectly happy editing the footage from this camera in a 60i timeline.

I had no illusions about what this camera is when I bought it---an affordable high-def *consumer* cam with 24p. This camera is targeted towards me in this regard.

It's great to push the envelope with consumer gear, but I don't expect it to have pro level features that the target market for this camera won't need or appreciate.

If one needs those features, I suspect they should be looking at the prosumer gear.

I would hate to see Canon pull this feature from future cameras just because it is more trouble than its worth.

Ray, what you are saying is a legitimate concern, especially given your example of their not including RAW mode in their "enthusiast" G7 still camera. However, see the next paragraph and I think panic about their doing this with 24p is not warranted yet.

Until better sensors are developed, we should not see 24p in the HV20 as any kind of "pro" feature. It's a consumer feature in the truest sense. Its function for consumers is not to emulate a filmic look, but to enable shooting indoors without the use of lights. This is the sole reason many educated consumers are buying the Canon over the Sony. When you switch to 24p, especially with CINE mode on, indoor shooting suddenly becomes possible in regular light! This is a tremendous feature of the camera. Who wants to use a camera-mounted light, or turn on all the lights in the room, when shooting family, friends, a party, etc.? This is not how consumers want to use a video camera.

It's implemented poorly, however. First, it drives me NUTS that I have to do something like 14 button presses to switch from 60i P mode to 24p CINE mode, and another 14 to go back again. These are the two modes where the HV20 shines for a non-pro who just wants to record memories. Good light, and low light. (Perhaps this is again fixable via firmware, to be added to the quick-access menu, but I'm not holding my breath.)

Second, to have this mode which is so useful and not have it work with editing software is even worse. And if they can fix it with firmware, they should. This is a new model. This is an important feature. They should make it work better than it does.

I don't want to go out on a limb and claim that new and better software is on its way to support the HV20 in 24P mode... and please understand I'm a windows user of Adobe products... so having said that, the Adobe software that " might " support the HV20 in 24P mode is still in Beta testing. Adobe claims it is to be released on July 15th.... so I guess we all have to wait and
see if this software will handle it... but even that software wont be a cheap upgrade. The beta software that is being tested won't even support HD video yet, it will be when its released. So the only way that we have been able to work with CS3 product is because folks like Cineform have released the software and we just manually overide the installation and force the Adobe software to accept our HD inputs... so we know that workflow
works and Cineform is working bugs real time... ya gota like them just for that fact alone... much less that they have a product that works perfect now with the HV20....

Black Magic is also working with us on the HV20 with real time capture...
From what I've seen so far the Cineform/BlackMagic solution to live capture
is working perfect.... so those two company's seem to be getting it right....

I guess Canon could have written there own software editing solution, but I think they may have learned the lesson with the still cams...

They make very nice cameras, but they are not a software house....
so they expect you to buy their cams and you choose what editor to use.
A good buisness model if you ask me... that way you get to choose between windows, Apple or whatever and within those platforms you get to choose a company to work your video's with....

I agree with what you are saying Steve. That was my gripe from the start...that their advertising this as true 24P was kind of misleading.

The camera does do 24p exactly like it is advertised. 24p is 24p. How you edit it is a whole other issue that isn't up to Canon. When 24p DV cameras first came out no NLE supported them. People did not yell at Panasonic saying that the camera didn't give them 24p. The camera did give them 24p but there needed to be a way to deal with that 24p which was hard at first. This camera is not much different. It shoots 24p but it is up to us to figure out how to use it. 24p is not supposed to be easy to work with. Even without pulldown issues there are a lot of other complications that go along with true 24p editing. Canon needed to make the style of 24p from the HV20 as easy to deal with as they could in order to make it so everybody who picked up the camera could shoot and edit stuff that had a 24p look to it.

Whats funny is if Canon would have called the 24p something else like SONY did with Cineframe24 or how Canon did with 24F then half the people on this board would be trying to figure out why they didn't just call it 24p. It's 24p because the chip is scanned 24 times per second as true progressive frames. In fact no other HDV camera out there right now can do this without some sort of pixel magic.

Having done the 24p workaround it's not that bad. I was DREADING it the first time. But now it's "whatever." Sure, Canon should have put the flags in there, and I'm sure it was a deliberate omission, but for $950 the camera is a beast, so I can't complain much. I'm not doing any film outs right now so it's really not hurting me much if I don't use 24. De-interlacing to 30 suites me just fine. And if I the need arises, I'll just have to do the 24p workaround.

In fact no other HDV camera out there right now can do this without some sort of pixel magic.You are correct when you say that it does what it is supposed to do. When the DVX first came out there was no NLE support to remove the 24P. We just might br barking down the wrong tree trying to get Canon to add flags etc. It does not hurt to voice our concerns though. If they acknowledge them in our favor then more power to the people. If not then we will more than likely settle for the route that the DVX took and wait for the various NLE's to support this version of 24P.

My original gripe had to do with what I considered misleading advertising. I was upset that Canon's "bar scene" footage was smooth and had no artifacts (ghosting or blending) unlike the footage the rest of us were getting on our own cams. That was until i took another close look. The video was shot in a way where there was not much movement overall and was very short compared to all of their other cams (including the HV10). I can't speak for anyone else but I felt like the footage was trying to mask something by using short pans and cuts with not much movement. The only real heavy movement in that video is when the bartender shakes the drink mix. Other than that there is movement when the woman takes a seat at the bar. That is what caught my attention. I noticed some ghosting/blending. I realized that Canon did not use any special technique to remove the pulldown but they kept it in the footage. So... we are left with the same and now it seems that it is up to us to figure out a way to remove it.

I think if we give it some time, just like the DVX, the NLE's will catch up and find a way to remove pulldown. We know it can be done without the use of flags (Cineform, Steve's .exe file etc.). Though it would have been nice if Canon included a capturing device that did it from the jump.

OK - so here's what's going on: My initial contact with Mr. Ishizuka was to pass along my overall satisfaction with the HV20. I really do feel it's a great camera and expressed that in my email. He responded in kind, thanking me for my email. I then replied with another email raising the 24p flag issue.

That was Monday and I never heard back from him directly. But today (Friday) I got an email from Canon Support saying Mr. Ishizuka had passed along my message and that they were going to "study the mater right away and determine the most appropriate resolution." The email continues:

"For that reason, I'm asking for your patience and cooperation while we
conduct our research. Once we reach a conclusion, we will again reply
to you and work toward making our conclusion publicly known as well."

The email is signed by a "Customer Relations Representative".

So... I'm not really sure what to make of this. Initially, I thought they were just blowing me off. But on closer look, I think they might be taking the issue seriously. First, it wasn't the form response we've been seeing elsewhere on the issue. Second, what's the reference to "making our conclusion publicly known"? Does this mean they've heard enough about it from all of us that some kind of announcement will be made? Third - "Customer Relations Rep" - is that different from whom other people are getting responses from? (And maybe I'm reading too much into this and they are blowing me off. ;-) )

If I didn't hear back from him this week I was going to suggest that for those who are interested, we send a form email of our own to Mr. Ishizuka. I'd draft something that people can cut and paste and email (or mail) directly to him (of course people can edit the form if they like.) I have to think if he gets a few hundred highly similar emails from different people, he'll see there's some orgranization behind the request and that may prompt him to take it more seriously. (From what I can tell, Ishizuka is the head guy in the US for Canon's Consumer Imaging Products division, which includes all their non-pro camcorders and digital cameras).

However since I did get the support email, I think we should hold off and see what comes next.

Also, I recognize not everyone who reads this thread is in agreement on pursuing the matter further - or at all - with Canon. I understand that. Anything I send or suggest sending would be respectful and cooperative in tone. Still I don't see any harm in letting our concerns as customers be made known. I think it's worth playing this out to see where it goes.

Alright guys - finally got my reply and unfortunately, it's not what I was hoping for:

Dear Mr. Alessandria,

On behalf of Mr. Ishizuka and Canon U.S.A., Inc., we have concluded our review and study of your questions regarding editing video footage with the HV20 in 24p mode.

The Canon HV20 HD camcorder 24p Cinema Mode is intended to give the look of film when viewing on a television set or monitor. We have explored this matter thoroughly and reiterate that there are no plans to modify the HV20's feature set in any way. For true 24 frame production, we recommend the Canon XH A1, XH G1, or XL H1.

Once again, thank you for your interest in Canon products.

Sincerely,
Cathleen Combs
Senior Manager, Customer Support Operations
Canon USA, Inc.

My reply:

Dear Ms. Combs -

I am very disappointed that Canon has decided not to add the flags necessary for pulldown removal when shooting 24p with the HV20. I purchased this camera specifically for the 24p feature. As you know, without those flags, removing pulldown and editing the HV20's files as 24p is not currently possible with most of the major NLE software packages. It seems strange Canon would include such an exciting feature like 24p, but then not give its customers the abilitiy to take full advantage of that feature.

My disappointment notwithstanding, I do appreciate you and Mr. Ishizuka looking into the issue. I remain an appreciative Canon customer and was sincere when I said the HV20 is a great camera.

Best wishes,

Peter Alessandria

So where do we go from here? I am considering posting Mr. Ishizuka's email address here for people who want to send their own email on the issue. But I don't want it to be used to harass or disparage him or Canon. What do you guys think?

I am considering posting Mr. Ishizuka's email address here for people who want to send their own email on the issue. But I don't want it to be used to harass or disparage him or Canon. What do you guys think?

I think "no". I don't see anything good coming out of posting Mr I's email address publicly.

That being said, I've felt this letter writing campaign and cries of false advertising were way over the top since the very beginning, so feel free to take that into account.

But no, I don't see what would be accomplished by having people write to him directly. The camera functions exactly how they intended it and, for people who want to reverse the pulldown, there are plenty of options.

For true 24 frame production, we recommend the Canon XH A1, XH G1, or XL H1.



This response clearly confirms that Canon in no way wants its little consumer wonder camera to compete with the professional level cameras they are selling for 4 times as much.

So you end up paying Cineform $250 to add the pull down they didn't want to add.

I am considering posting Mr. Ishizuka's email address here for people who want to send their own email on the issue.No need to even consider it, because I wouldn't allow such thing here to begin with. DV Info Net operates on certain standards which make this place different from other message boards on the web. If the desire is to launch a crusade upon Mr. Ishizuka, that will have to be undertaken elsewhere on the Internet. I think David Garvin's post above has summed up the situation well, and we're probably at the end of the road for this thread. Thanks in advance,

Well I hope my post made it clear I didn't want a crusade - just an opportunity for customers to express themselves in a respectful manner. I suspect he'd welcome that. Canon prides itself on such things.

I just called Canon about the pulldown flags. The guy told me that it's up to the application to "force" the pulldown, even if the flags are not there (which takes Vegas out of the picture because it won't do it if the flags are not there). I explained to them that the flags are missing and that other camcorders that support 24f do have the right flags, and he said that because this is a consumer class camcorder, there are NO planned updates to address this issue and he said that the pulldown is done correctly when playing back to TV, which is the main playback medium that Canon is interested in regarding the HV20 and 24f.

In other words, they won't fix it, and there is a good chance that future models will have the same limitation too.

The HV20 does not record 24F like the XL H1 and XH cameras (in which 23.976 fps progressive frames are recorded to tape and no pulldown flags are needed). Rather, it records 24fps in a 60i 2:3 pulldown to tape.

However, the XL H1 and XH cameras do send pulldown 60i via SDI...I'm curious if anyone has confirmed whether or not there are pulldown flags in that stream? I don't know, but guess I'd be a little surprised if there are.

I'm just happy that there are all these options, other than waiting for Canon to make a change. Cineform, though it cost around $300, is THE BEST one step pulldown removal for the PC. $1099 + $299 = still cheaper than the H1, G1, A1! Plus, you can do so much more with it, like down convert to 720p or 480p, de-interlace your 1080p stuff, and for all those who are saving up for the Intensity card, can use this codec on HDMI capture.

The new FCS 2 has a new self-contained option through Compressor 3, no extra cost with Final Cut STUDIO. Even the free JES program is an excellent one step process for Final Cut Pro (if without Compressor).

As a result, the pulldown removal threads have become dead in the water to me. The software companies are making the adjustments. Although Canon did it dirty, this camera has been selling like a hotcake. They are in no hurry to spend resources on a product that is still in such high demand. Let them have it! I'll be busy making movies!

That being said, I've felt this letter writing campaign and cries of false advertising were way over the top since the very beginning, so feel free to take that into account.

But no, I don't see what would be accomplished by having people write to him directly. The camera functions exactly how they intended it and, for people who want to reverse the pulldown, there are plenty of options.

I think the claim of the HV20 being a 24p camcorder is indeed false advertising. It does not record 24p. And the 30fps video that the HV20 does record can not be correctly converted to 24p without residual interlacing every fourth frame, no matter what process you use. 'Interlaced' is not 'progressive.' The 4th frame problem is quite apparent to my eye during playback. And I was also hoping to be able to key elements I shot with the HV20. But they are ruined by this lingering 4th frame interlace.

Who would expect a "24p camcorder" to not record 24p, and to have no option for 24p playback? To me this is like claiming a TV is HD that doesnt actually come with an HD tuner. It is instead called 'HD ready' meaning it is capable of HD when you buy a separate tuner. Just like the HV20 is '24p ready' but you have to buy more stuff to actually get 24p out of the recording.

But before you tell me how I just dont know what I am talking about (for the thousandth time), please read here-
http://dvinfo.net/conf/showthread.php?t=99792&highlight=HV20+24p

How do you remove pulldown?

After I remove pulldown I don't see any evidence of interlaced frames.

As I mentioned on your other post this is the same way the DVX implements its 24p footage (with the exception of flags). This method has been used for many years and the HV20 is no different.
