i went to a HVX-200 demo here in austin yesterday sponsered by Omega Broadcast Group - special thanks to allan barnwell for setting it up & letting me take home the footage:

http://www.omegaaustin.com/

got some greenscreen footage for you guys... i don't have alot of data transfer, so i don't know how long i can keep the clips on my site... if someone else can host them, that would be great and i'll put more clips up. there is a 8sec DVCPRO-HD greenscreen clip & a 21sec H.264 of water splashing on a hand (slo-mo)...

clips shot by dan parsons.

edit: clips moved here

Great !

what were the HVX settings Danny ?
It looks very sharp, clear, clean.

Great !

what were the HVX settings Danny ?
It looks very sharp, clear, clean.

i sent an email to dan parsons (dp who shot it) asking him to post that info. all i remember about the water stuff was that it was warm-balanced (white balance on blue sky) and had a 1/500 shutter speed. if i find out more info, i'll let you know.

Thanks for the PNG. Seems pretty easy to key. This was done in Vegas using chroma blur and chroma keyer effects. (back ground is a random pic):
http://www.savvyproductions.com/imagekeyed.png Although it is hard to judge from a still cause the moving image could still potentially have "dancing edges" . But, things are looking really good for greenscreen with this cam.

there are more clips in that package to check out.

I used AE to apply the Keylight filter and with very little tweaking got this:

Now I've had very good results even with DV using Keylight, but it always required more tweaking than this clip. Oh yes, this clip is without bluring or chocking the matte.

I'm willing to help mirror the files on my server, but I would really appreciate it if someone could make a WMVHD file for the PC viewers to see.

Stevet

01-10-2006, 08:11 PM

Is there a secret to making this MXF file work with AVID Xpress Pro HD 5.21 for PC?
It errors when loading with some sort of XDCAM error. I can't remember exactly?

Thanks

Also, please someone make a decent WMV file for those (including myself) that can't view this MXF 720P file?

Mr. Blonde

01-10-2006, 08:21 PM

Steve....copy the mxf file into: "Avid MediaFiles\MXF\1" folder and then open the Media Tool under the tools bar. Select the drive to which your mxf\1 folder is stored on. Then you should see all the MXF files in the media tool bin, drag the mxf into the regular bin, then down to the timeline. =)

Stevet

01-10-2006, 08:29 PM

Thanks man!
I'll have to try this.
I'll let ya know.

Apparently there must be other AVID overhead code that looks in that directory?
It's odd it errors when reading from another directory.

Is there any way I can get this clip in AfterEffects 6.5?

dougspice

01-10-2006, 09:08 PM

Yeah, just export it out as a Quicktime. I'm playing with one of these right now in Color Finesse... holds up pretty damn well, I have to say. I'm even pulling secondaries off the sky in that bottle-toss clip, grading the sky different from the rest, and it's pretty solid. Oh, sweet sweet color resolution, how I've missed you!

Mr. Blonde

01-10-2006, 09:50 PM

Here's a key that I took off of the footage, resized to fit in here also. Here's an idea of what you can do in a matter of minutes. =)

[QUOTE=Mr. Blonde]Here's a key that I did off the footage, it's a bit squished for some strange reason but here's an idea of what you can do in a matter of minutes. =)

did you resize to 1280? i had to when i made the H.264 clip... the DVCPRO clips are 960 X 720 but open in FCP at 1280.. took me a while to figure that out (never encoded DVCPRO files before).

Great shot!

First head shot I've seen that's actually in focus and lit well.

Maybe not as sharp as the H1, but the skin colors are terrific... filmlike.

No artifacting that's gonna hurt chromakeying that I can see... far as I'm concern, it seals the deal for greenscreen work.

Thanks!:thumbsup:

Oh. I think DV Filmmaker has an MXF converter on their website. Just do a search for "mxf import" or "mxf converter", maybe also for avi? You'll find tools that will do it. Some are free.

Wish the bandwidth would reset so I could see the entire clip of course, but the stills look great.

Dmitry Kichenko

Yeah, thanks. I've tried importing one of the clips before though, and it spit out errors. I've installed an update yesterday, let's see if it works now.

Mr. Blonde

01-12-2006, 05:10 PM

Kichenko, might that be Russian?

Dmitry Kichenko

01-12-2006, 05:14 PM

Born in Russia, then moved to Ukraine, then here to Canada, hehe.

As to Avid - it still gives me errors. The footage won't get previewed in either of the monitors, and exporting as a reference file to check the playback in QT doesn't help either. I'll blame this on my relatively old Athlon based PC.
So.. It'd be nice to have someone render out a TIFF sequence :).

Ah Dmitry, harasho. My family's from Yalta and Kursk. =)

As for Avid, do you have version 5.2.1? It's working perfect for me, if you need help, I can tell ya how to get it working.

Dmitry Kichenko

01-12-2006, 05:52 PM

Yeah, that's the version I have. I followed all the instructions I found in various posts here on the board but none of them got it working. I heard that Avid may not behave as expected with CPUs other than from Intel (how descriminative, hehe) so I thought it might be that.

Mr. Blonde

01-12-2006, 05:57 PM

I'm running an AMD64 with avid and everything is fine....hmmm. Here's the way that I do it....

1.) Copy the MXF files to drive:\Avid MediaFiles\MXF\1

Use the Copy function rather than Move. You can copy the contents of the video and audio folders from the P2 card to the MXF\1 folder - they can reside in the same directory.

2.) Once copied over, go to Tools, Media Tool. From the window that opens, select the appropriate drive path where you copied the MXF data files. This will create a Media Tool bin containing the MXF files.

3.) Finally, select and drag the MXF files into the project bin from the media tool bin and then drag them down from the project bin onto the timeline.

Justin_Kirch

01-12-2006, 06:02 PM

for the love of god, can someone just make a pc version for those of us who don't have avid or anything else....or just get the clip up again. can someone host the clip again please?

Dmitry Kichenko

01-12-2006, 07:40 PM

Blonde - I went through various revisions of the same instructions on this board multiple times. None of them helped.
The one you pasted was in the post Isaac linked to. Besides, the "Copy, not Move" suggestion is for those copying off the P2 card, not from HDD to HDD.

Ok kids. Here's my composite in Shake 4.0 using Keylight. I was very impressed with the HVX. Seems as though the blue channel is the noisiest. Stay away from blue screens! Keep in mind that this clip has been compressed for the web.

Haakon

01-12-2006, 11:35 PM

Wow, bgundu... that looks awesome. I don't suppose you can "squeeze" the other clips that came from the zip? A bunch of us PC users still haven't seen half this stuff.

Mr. Blonde

01-13-2006, 12:29 AM

Nice Bgundu. Can't wait to get my HVX and do some indie Sin City flicks! =)

Dmitry Kichenko

01-13-2006, 12:48 AM

Squeezing won't do. We need the original footage, not the Sorenson video compressed clips.

The video indeed looked nice, and that's even with all the soft edging and little despill. Nice :).

Bgundu - was the grain on the background added artificially or is it just the grain from the actual greenscreen that just wasn't keyed out well? It looks to me like noise from the greenscreen.

EDIT: After messing for a while with the older screen grab, I came up with this:
http://www.gleb.zerobrains.com/dmitry/images/HVX_key_3.tif

Still not quite happy with hair and the left side of the face, but as the clips prove, when the frames are in motion, the fine details aren't as noticeable.

I'm not interested in keying anything, I just want to see the stuff. The compression bgundu used on his key looked fantastic, and PC users can't see the "original footage" without some kind of conversion.

PLEASE convert the original clips with Sorenson, and if you need hosting space/bandwidth, I will be happy to provide.

Thank you in advance.

P.S. - Is anyone able to read the metadata and determine what detail level was set for these clips?

hey haakon... i have the original footage - DVCPRO files that were unwrapped from the mxf files (can't give you metadata info) - and i have Squeeze 4. i'll convert it for ya... if... you can tell me what happened to shannon's thread - the one where he came asking permission to speak. i came home last night and found the thread deleted and you are the only one who commented (on the 4 cam test thread) that he got banned... for what? pm me if you have to - it seems no one is talking or asking about it...

01-13-2006, 04:00 PM

Ok kids. Here's my composite in Shake 4.0 using Keylight.
Bob

Hey, Bob, thanks for posting the clip in Sorenson! While H264 has its uses, I think that good old Sorenson does a fine job, and doesn't jack up the gamma. I used it as well for my 3D tracking test.

Great key work, I see you addressed that thin dark line on his shoulders/ears, which is simply lack of fill light to counter the green spill, quite nicely. Most of the key examples I've seen with this clp kind of let that slip by or over choke that puppy. :) I can't access the raw footage, but when I took that tiff of a frame into AE I just breathed a sigh of relief. It will work as advertised.

Anyway, based on this and other examples I've seen, the HVX will be best in class for keying, period. Sure, hook up your Canon to your, ah, "portable" HD-SDI NLE if you want, but for out-of-the-box, in-the-field keying goodness the HVX can't be beat. And this is with HD material and higher compression... that DVCPRO 50 will simply rule the SD world for inexpensive key sourcing.

My biggest fears until recently were with the HVX having A.) too soft a picture with detail set very low (as my Z1 was... anything less than 10 was way too soft) or B.) some trace of edge enhancement still visible at those low detail levels. Edge enhancement is a matte killer... simply unusable without massive choking or extensive hand work.

Many factors will influence a decision on which camera to buy. I place keying high on my personal list, and keying from the cameras built in recording media even higher. Add over and under-cranking, shooting 1080 for FX plates, and the first ever in a prosumer camcorder ability to do true single frame and interval recording, I am 100% sold.

Thanks to danny dale, we FINALLY have these clips in a PC-viewable Quicktime (Sorenson, not h.264) format for viewing. I really appreciate him converting these for us since there is so little PC-friendly footage available and no one has risen to the occasion of converting anything else.

Here's a quick test in AE. Definitely not as nice as keying 4:2:2 source but decent enough. Would look great when converted to SD.

Isaac_Brody

01-14-2006, 01:12 PM

Danilo, do you have the M2 file for that footage? A jpg file adds exta compression and it would be best to key the source material.

Danilo Del Tufo

01-14-2006, 01:16 PM

Yes, you can find the originals here, also the footage (149 megs in dvcpro)

http://homepage.mac.com/WebObjects/FileSharing.woa/64/wo/JUl1zyLJUTVnV2nb.1/0.2.1.2.26.31.97.2.35.0.1.1.1?user=kevinwild&fpath=H1_GreenscreenTests&templatefn=FileSharing34.html

I've seen some new footage from Canon Xl H1, a night city...guys it's incredible the detail! Also the colors are very good.

Dmitry Kichenko

01-14-2006, 01:18 PM

First of all, it's a JPEG file, so I can't say we can be too objective in the comparison.

But if it's not the compression and it is the HDV artifacts around the ears and on the neck, then HVX200 easily wins. It's kind of to be expected though. 100mbit HD... 25mbit HDV..

Shaw - decent enough? Where did all the hair go, what's up with his ears and neck?

Danilo Del Tufo

01-14-2006, 01:20 PM

For Example: H1Greenscreen1080i_8bitUncomp3.pct in the link that I've posted.

Shaw - decent enough? Where did all the hair go, what's up with his ears and neck?

Good question. It's not great but it would work if you had to use it. Decent enough meaning it is what I would expect from a straight key of a 4:2:0 format. I would normally throw a matte choker on as well but I wanted to see what sort of details I could retain in the hair. A choker would go a long way in improving this composite.

Danilo Del Tufo

01-14-2006, 01:36 PM

Yeah...I'm on the pc too, but you can open with quicktime, but it's impossible to open with Photoshop I think...

Isaac_Brody

You can open pict files with quicktime and then export them as tiff, photoshop, or any other variant. How about the keying gurus try out the DVCPro-HD file?

Here is a relatively fast key:
http://www.gleb.zerobrains.com/dmitry/images/XLH1.Key.1.tiff
The hair was pulled with Keylight, and the rest with Primatte.
Clearly the problem, as expected, is the artifacts produced by the interlacing and less colour information as compared to DVCPRO. Deinterlacing will inevitably bring the overall quality down.. I will try it tonight though.

01-15-2006, 06:08 PM

Before getting into keying, here is a bit of comparison of what the two cameras are capable of in terms of luminance and chroma information:

HVX200 (http://www.gleb.zerobrains.com/dmitry/images/HVX.ColourSpace.Comparison.1.tif)
XL H1 (http://www.gleb.zerobrains.com/dmitry/images/XLH1.ColourSpace.Comparison.1.tif)

Unless I'm missing something the Canon is a LOT sharper. (Too sharp for human faces I think)

Of course, once you get output from HD-SDI the Canon trounces the HVX for greenscreen. Sharper, 4:2:2 and uncompressed.

So far I'm seeing the HXV as a 720p camera. We're not seeing anything that shows more resolution when shot at 1080p. You'd think there'd be a test of that by now, is there?

re: the colorspace - We all know 4:2:2 is there on the HVX, but is it really capturing it enough to show against the other cameras? If I can't see it is it really there? (Adam Wilt to the rescue?)

And what are you going to record that on? The world is about little tradeoffs, this one meand that you have to go to uncompressed for record, and that is generally possible in the studio, but how do you capture those back grounds and frankly that means the entire time line kicked up the storage a couple of notches.

If you're doing a lot of greenscreen you're usually in a studio. And yes... you'd be recording to a fast raid (build your own for $1k to $3k these days) via Kona (add up to another $3k). I agree with you entirely, there are trade offs.

This clip here was HDV and it's sharp and very keyable. But it doesn't tell us anything about fast motion. If that 24F isn't really putting nice clean frames together than it could be real trouble just like the Sony.

So far I'm not buying all the HDV bashing other than the fact that it's a pain in the butt to work with on a Mac currently. My one P2 test was EASY - I'll toss you that bone for sure. :-)

Jim Arthurs

01-15-2006, 09:55 PM

I just said very nice things about the Canon resolution in a different thread, now I'd like to point out a few things about this example (going off of the still images).

First, the greenscreen has color ratios that are set up quite well. If someone was to use the HVX alongside the Canon on this shoot, it would be the best example we've yet seen from the HVX and key very, very well.

Second, there's all kinds of compression and other issues in the image that I remember from my days attempting keys with the Z1.

As an aside, dark hair against green always works, as it becomes a luma key on the green channel, but slap a blonde-haired subject up there and see what happens. Those artifacts will kill your key. Just look at the shoulder area as it transitions from green to grey sweatshirt... de-interlace and see that the problem is built into the image at the field level.

I have no doubt that the Canon tethered up would produce the sharpest images of any of these 1/3" cameras. Ironically, I'm set up to take full advantage in the studio of that, as my VelocityHD just loves HD-SDI and I could balance the compression of the NLE against the file size to find a very nice match. But, that ain't gonna happen. If I need that, I just as well pony-up rental for the 700a I use for interlace capture and get a "real" camera that will blow the little ones away.

The HVX is a terrific balance of features and codec quality that's self-contained.

Again, unless I'm missing something there shouldn't be any deinterlacing going on with the Canon or the JVC. That's a Sony problem... keying that camera has always been a nightmare. None of these should be that bad.

The title of the still images have "1080i" in the file name, and you can see subtle interlacing in areas where the subject is moving...

...I'm saying that after de-interlacing the frame, the HDV codec artifacts are more easily visible and quite nasty.

Having seen the footage and still from both cameras, I'd say that the H1 would be more appropriate as a studio camera with its SDI output. But.. How many of us need a studio-only camera?
Therefore, HVX becomes more of an "all around" camera that can serve multiple purposes without too many trade offs and with relative.. no... good... great success!

I think you were keying HDV right? There was a lot of edge detail there and no weird compression artifacting that I saw. It's Discover Channel HD approved... I'm kinda guessing they Ok'd stuff shot on HDV that was outdoors.

That's a pretty solid seal of approval if that's what you shoot. So great in the studio, great in the field. But 30% more expensive.

I honestly didn't see that much more detail from H1 than from HVX. And besides, looking at the outlining on the neck on the H1 grab, I'd say the greater detail is either a result of the sharpening or the MPEG2 codec.

Discovery Channel does NOT approve HDV. I edit there (freelance) and know the Manager of post.

Which post exactly are you replying to? I presume it's Isaac's post with a link to the source clips. I got it succesfully, let me see if I can upload it to one of the free hosting services.

Dimitry, that looks awesome! Completely believeable.

Has anyone tried keying 1080 footage? This is all 720p, right?

And thanks everyone for putting up the Sorenson clips. The water clip looks amazing!

I am looking for an uncompressed copy of the HVX greenscreen footage for a PC. If someone could post it I would be Grateful

Wowie.

After looking at these HVX clips, I had two thoughts:

1) Professional greenscreen results are easily within a semi-pro's grasp with the HVX.

2) We're going to be inundated with entirely too much unnecessary-yet-beautifully-shot slo-mo from hoardes of wannabe filmmakers. gaaah!

I think that filmaking will be returned to artists again instead of accountants. This will result in a lot of films in the coming years. But this will be a good thing in the long run.

After trying a few combinations of keyers in Shake, I settled on this:
http://www.gleb.zerobrains.com/dmitry/images/HVX_key_2.tif
This took a bit of time to assemble and I'm still not completely happy with how primatte pulled the hair on the left side but overall I'm quite pleased with the result. I added a slight amount of grain to the image to get a bit closer to the film look. You be the judges.
Edit: In case anyone's interested, I uploaded the tree (http://www.gleb.zerobrains.com/dmitry/images/HVX200.keying.tree.2.png).

Dmitry, that is really amazing. I would never know the subject wasn't at that location. Really impressive still.

Wish the bandwidth would reset so I could see the entire clip of course, but the stills look great.

If you look better you defenitely see that is not on that location. The lighting is totaly not wat it should be when he was realy on that location. If I look at the background I see a lot diffused sunlight. In this picture he has many too dark areas on his body to be realy there. No backlight on his shoulders, top of his head is too dark, to much shades for such bright day.
Don't get me wrong. The greenscreen is good but that's all. No way that I should think he was really there.

I believe this was a keying test and not a shot for a feature film I'm paid to work on.

Here's a quick test in AE. Definitely not as nice as keying 4:2:2 source but decent enough. Would look great when converted to SD.

The sharpness of the Canon H1 is amazing. You can see the pores on the guy's face. :shocked:

While the H1 composite is still pretty good, it's nowhere as seamless as Bob's composite with Hvx200 footage.

You can detect the "outline" around the H1 composite... like someone's used a a magic marker around the guy. Dunno whether that's due to different compositers using different compositing programs, or the nature of 4.2.2 versus 4.2.0 color.

My next project will contain at least 80% green screening.

The HVX200 is heaven sent, that's all I can say.:happy:
