I have a few avi videos that are encoded with the mp4v fourcc codec. I have Sony Vegas Pro 8 and it will not open the video part. It will bring the files into the file manager, but when I drag them into the project timeline they only show the audio track as if there is no video track at all. There is no error message at all.

I would like to be able to resolve this without converting the files.

If it helps, they were encoded with ffmpeg –  fredsbend Jan 14 at 20:29
    
You might want to consult with sonycreativesoftware.com/support/technicalsupport.asp please read their knowledge base first to see if your issue has already been covered. –  filzilla Jan 15 at 22:52
    
@filzilla Searching that site for mp4v yields no results. –  fredsbend Jan 15 at 23:16
    
He can still open a trouble ticket with Sony Creative Software. –  filzilla Jan 16 at 17:30

I resolved this issue by installing VLC. Apparently VLC has some necessary codecs that Vegas Pro uses.

After installing VLC I was able to import the video and use it normally with no hindrances.
