Working with DVC Pro 50 in Vegas 12

[andrewgerm]

Good day all
I have searched about for a solution to this, but seem to be finding conflicting answers.

I have a few files in DVC Pro 50 format, in QuickTime containers.
When I drop these into Vegas, I am getting 4 audio tracks, and no video. If I try view them in QuickTime, I get video and no audio.

MediaInfo says they each contain 1 video stream DV and 3 audio streams all PCM.

From what I can gather, Vegas can support DVC Pro.

Do I need to purchase an additional plugin? Is there one available for download? Or am I missing something?

I have the very latest QuickTime player. Everything i srunning on Vista 64 Premium.

Any input would be appreciated.

The only Quicktime option that comes to mind on Windows PC is the Raylight brand or Calibrated brand DV50 codec plugins, both of which cost $$.

A free option would be to use matrox vfw codecs (vegas can use them) , but it requires that your video be AVI wrapped . If it's mov wrapped it will bypass the VFW system
http://www.matrox.com/video/en/support/windows/vfw_software_codecs/downloads/softwares/version1.0/

So you can do the re-wrap in ffmpeg , but you have to specify -vtag "dv50"

ffmpeg -i input.mov -vcodec copy -an -vtag "dv50" output.avi

This works ok on an older version of vegas on DVCPro50 MOV files , and you can batch process if you have a lot of them with ffmpeg. You can mux audio too if you want by using the -map command, or just import the audio separately as you're doing now

The other option is to encode to some intermediate format for editing

Or if these options are too much hassle, and you frequently deal with these files, one of the plugins Cornucopia mentioned might be worth purchasing

i'm guessing it's the apple mov container screwing up the import. if you could re-mux it into an avi container it should work.

Thank you all for the replies.

I think it is Apple MOV wrapped, so will try ffmpeg and see how that works.
VLC see each audio as a track, but importing as is, and getting the audio, I think this should be a viable solution.

Will try those first, and maybe I can write a script if used more often, or look at the suggested plugins.

Once again a very prompt, and helpful reply from these forums.

Will post my results once I try this, in case it helps others.

Good day all
Just an update on my attempts.

I have re-wrapped the files using ffmpeg (grabbed the latest version of that too while I was at it). Also grabbed the latest Matrox codecs.

Taking the new AVI file, I could lay that on a video track, and then drop the original MOV file into Vegas. This produced 4 audio tracks (one was silent, as I think Vegas was confusing the video stream as audio, due to codec issues). These all lined up perfectly, and I am able to play the video successfully.

The three audio tracks play to present all sounds (music, dialogue, effects) in syn with picture. There are a few issues with some of the frames in the video, but I'm sure I can work around those somehow. When it comes ot anything where I can't work around those corrupted frames, I guess I'll have to look at some other plugins. But that's all fine for now.

Thank you all again for the very quick, and helpful responses.

What do the corrupted frames look like ?

If you open the same AVI in vdub are the same corresponding frames corrupted ? (check in vdub with file=>file information to see what VFW decoder is being used, it should be the same as the one in vegas; to do that in vegas right click the clip and check properties)

If it's an issue with the matrox DVCPro50 decoder - An alternative free DVCPro50 decoder is in ffdshow, you have to enable it in the VFW configuration (not the directshow configuration) . To do this , you must also temporarily disable the matrox codec with vcswap (find the entry and right click and click disable) . Now again check with vdub file=>file information to see what VFW decoder is currently being used for fourcc "DV50" , it should be ffdshow

[andrewgerm]

@poisendeathrayThe best way to describe them, is to say that there are some large blocks that appear corrupted, while the rest of the frame seems okay. I am able to work around these in this particular case, but obviously it's not good for future.


I have not had a chance yet to test the other files (I have about 10 of the DVCPro 50 files) so will check those soonest, and grab vdub. I have the latest version of the Matrox codec, so if the other files are corrupted, I will try ffdshow.


I am able to view the video stream of the original files via VLC, and those frames are not corrupted as such in there.


Thank again, and will post feedback when I get to the files tomorrow.
