From what I can tell, this is XDCAM EX video, which is encoded in MP42 codec in an MP4 container. Vegas Pro won't even look at it. Says the file cannot be opened. How can I fix this? I can convert it (I've done Handbrake and VLC already to test), but I'd rather not, because I actually have tons of these videos and converting takes lots of time.

mp42 is the container ID, which Mediainfo wrongly calls a codec id. It refers to MPEG-4 Part 14 spec for containers.

XDCAM is actually a Sony variant of MPEG-2 video. I've worked with XDCAM natively in Vegas, which were in MOV, I believe.

You can use FFmpeg to rewrap these files.

ffmpeg -i video.mp4 -c copy video.mov

Looks like MOVs only work on Macs. The command below also worked.

ffmpeg -i video.mp4 -c copy video.vob

(You'll have to switch to viewing All Files (*.*))

  • I upgraded to version 13. Loaded the original MP4 completely and without issue. It was fast too. Thanks again for all your help.
