Audio but no video -mystery solved

JackW wrote on 2/21/2015, 12:08 PM

Any ideas as to why I have audio when bringing this into Vegas 13 but no video?
The file plays in Windows Media Player with both.

The tape was sent by a client, so I have no idea what it was shot on, whether it is camera tape or a copy, etc.

try opening in vlc player or handbrake, then save as/render to mp4...

Thanks for the quick suggestion. I've opened the captured file already and rendered to mp4 in Handbrake. That works fine. Problem is that the client wants the file as an ave on a flash drive. The video is old -- 12 years -- and not very good to begin with; rendering to mp4 and then re-rendering to avi leaves it in worse shape than the original.

I guess if all else fails I'll have to go the mp4 route, but that leaves unanswered the question of why the avi file won't open with video in Vegas. Perhaps someone can answer that from the MediaInfo analysis.

You could render in something or other app to .avi or at least better... than an mp4 class.. if you need to then bring separate renders of audio and video streams back into VegasPro for a combined file back to .avi.

According to the media info printout, your video is DV, using the dvsd codec. That is the most Vegas-friendly format there is.

Go to the Preferences, and make sure Vegas is configured to use its own DV codec.

If you have an earlier version of Vegas installed, try opening it in that.

I'm not sure I ever remember reading about someone not being able to open DV video.

Mystery solved -- a senior moment.

The Vegas window inadvertently became partially minimized, not much but enough to prevent the video timeline from showing. Several share this computer so I'm willing to assume (to preserve a little dignity) that someone else did this and I failed to notice.

Truth be told, though, I probably did it myself!

Thanks for your responses.
