Can't add video to vegas - file corrupted

aiki-a wrote on 11/16/2018, 6:49 AM

I'm having troubles with a .mov file that says to be corrupted when trying to add to vegas 13. File doesn't play audio in VLC, so smth's definitely wrong.

I got media info and it shows there are 2 audio channels but I have no idea how to access those or get the file to vegas to actually edit it... Help please (and know that I'm not that advanced :D) :)

I'd try to convert it with ffmpeg.

ffmpeg -i yourmovfile.mov -vcodec: copy -an newfile.mp4

That should convert the container, and drop audio. So you can salvage the video theoretically.

Maybe try to extract the audio too

ffmpeg -i yourmovfile.mov -vn newaudio.wav

and see if it does anything...

I see a couple of problems.

.. Your video is variable frame rate..

-- Your audio may be two channel mono, not a stereo track.

Try converting in Handbrake. You may need to import the result into a surround audio project, in Vegas, then pan to a stereo track

Or, if you can work with a command line, ffmpeg is the preferred option.

Just out of curiosity, I downloaded ffmpeg and tried the above command on a .mov file. It spat out all this text and produced a 0-byte-length output file:

@Red Prince Looks like you can't wrap ProRes in an mp4 container, which makes sense as I've never heard of such a thing. In that case a transcode to another stream format would be necessary, rather than just a rewrap. However a rewrap to the same mov container format might fix something and make the file more compatible.

Thanks, Nick! I have since tried a re-wrap and that did, indeed, work.

The reason I was trying to copy it to an MP4 file was in the hope Vegas would play it faster. But then I watched some YouTube tutorials and found out I could trim off the unnecessary portions and re-wrap the important part in another MOV with ffmpeg. This is because I use the Blackmagic Video Assist 4k to save the output of my camera, and since I am by myself, I have to turn on the Video Assist, then get in front of the camera, get in position and start talking, and when finished, I have to get back to the Assist and turn it off, so there is too much extra stuff at the beginning and at the end of the file. By trimming it, I can keep just the active part of the file and delete the original file without losing any quality.
