HD Black Magic Codec

jkrepner wrote on 6/29/2005, 8:53 AM
Hey gang, hoping someone can help.

I've got some footage that was captured directly from an HD telecine using the Black Magic codec.

I've copied the footage to my harddrive, installed the Black Magic 4.8 codec, but I can't seem to get anything to work with it. Vegas 6.0b sees the AVI as an audio only file, Premiere Pro Tryout version tells me that it is an unsupported compression file, and Windows Media Player tells me I need the correct codec.

I'm going to upgrade to Service Pack 2 on the suggestion of the Deck Link support team. I hope that helps, but I'd rather not do so unless I know that'll fix it. I think these files were captured by Premiere, using the Decklink SDI card.

Anyone have similar experiences they can share, or give me a pointer or two.,

Thanks.

Jeff

the BM codec would be a QT file, not a AVI afaik....

SP2 would make things worse , not better ...

How did you install BM codec ? I just dropped the file into the root of c drive and it works ..

check with g-spot to see what the file really is ..

QT? Interesting. I don't want SP2, I've only heard bad things about it.

Um, I downloaded the ZIP file and ran the installer. What do you mean you "dropped" it on the root of C?

Thanks.

it used to be that you could just download the BM core file as one file - you didnt have to install anything, now it is a MSI installer ....

but it is for quicktime wrapper ...

do you have a sample of the file or did you check it as i suggested ?

Note that there (on an apple) is some incompatability between different BM codec versions and color depths -- all you get is a black screen in some cases in Shake.

The BMD installer also includes their capture / media player. See if you can play the file with that. And yes they do seem to create .mov files. The SD file I captures did open in Vegas and it (Vegas) reports the codec as 2yuv. Capturing SD through Decklink using Vegas I get the codec as Sony YUV.

The Black Magic HD deal is based on Quicktime. if you have the files with an *.avi extension that would be the first issue. I could load up HD Black Magic files with no problems in Vegas 4 so I would'nt see any problems with Vegas 6 doing it.

And without any installer you would just take the "BlackmagicCodec.qtx" and drop it into XP where ever the Quicktime files (not the install directory, the system files) are - for me that is "C:\WINDOWS\system32\QuickTime"

SP2 runs fine for me, but this is a clean install on a new system. My older system is running SP1a still.

BJ_M,

I ran GSpot and it tells me that it is an OpenDML AVI. It sees the file size of 1920x1080, FPS: 23.976, the biterate and the Qf data. Stat: Codec NOT installed.

Farse,
When I ran the BM installer I didn't end up with any utilities/players as far as I could tell.

Filmy,
I did a search for "BlackmagicCodec.qtx" and copied it to my Quicktime folder. I can now view the file (sort of) in my quicktime viewer. Sort of as in, it won't play, but I can click around and see frames. Not sure if it's a harddrive throughput issue or not, it doesn't even pretend to play.

Vegas and Premiere still don't like footage, which is .AVI. Should this have come as .MOV from the lab?

I'll relay my info and try and get more details as to why this AVI and not MOV.

Thanks for your help.

Have you tried changing the extension to .mov and seeing what Vegas does?

Don't know why that is, I downloaded the package from their site and it installed a icon on the desktop to the deck controller which is also a player.

farse,

I got a link from BM tech and they had me reinstall the Decklink (after I installed SP2) and I now see the controller icon on my desktop. And yes, I can now play uncompressed HD from the decklink player, Quicktime 6.5 & 7, Premiere Pro, and Vegas (sort of).

Vegas allows me to import the HD file, but as soon as I park the playback head over it, Vegas goes away... no error message, nothing, just vanishes. If I double click the file in explorer within Vegas or try to view the clip in any way, Vegas vanishes into thin air. When I open, I get the message asking me if I wish to use the autosave project.

Premiere Pro seems to work well. Could it be that these files are 23.97 FPS? I didn't see a template in Vegas for 23.97.

Thanks guys, 95% there! I'd hate to resort to Adobe.

(p.s. I still can't seem to confirm if whether or not these HD BM files should be .mov or .avi. You guys tell me one thing, the lab the other, and BM didn't mention either way.)

there is one Telecine Transfer place (BonoLabs) that specifically says they ship BM AVI files to PC users , they use all MAC equipment and I'm not sure really what they are shipping ..
They also call them QT BM uncompressed files..

I had a client use them and I had a mess getting the files off mac formated drive for some reason and just ended up running them through Fusion to targa or CIN files I seem to recall. At least the Mac drives had QT files though, which SHOULD be the same thing they should ship to PC users .. I strongly suspect they are just uncompressed AVI with perhaps a odd header - evidence from your G-SPOT reading , which bears this out .... And has nothing to do with BM at all - unless that is the source of the header problems ...

load the files into AE or Fusion and just save them out as something else- myself I always prefer dealing with seq. frames from film sources.

B_JM,

You win the prize! It is BonoLabs and they have been great to work with so far.

Are you saying that Vegas would be happier if these files came in their native quicktime format? I don't care if they are TGAs, kodak files, or Microsoft Word Documents as long as they play!

I can get them to play in Premiere and I would assume AE. I can always convert to something that Vegas plays nice with.

Thanks.

honestly QT is slow to use in Vegas, if you can load the files into AE, Premiere or even Quciktime Pro, save them out as targa, uncompressed AVI, huffyuv (RGB) or something along those lines that does not use QT in vegas to decode them ..

BM also works fine in vegas - but 1. recompressing them to BM is very slow, 2. you deal with the native slowness of QT files in vegas.

I know all the hoopla about the quality of BM, BOXX also has a quality codec (as others) for QT .. but lossless compressed or uncompressed RGB files - well you check if any diff.

You could also move up to a 16 bit or floating codec, but vegas will always output 8bit anyway .. and compatability of greater of 10 bit in vegas you would have to deal with ..

if space is an issue - you can frame serve them from premiere to Vegas also ..
