Video Track No Longer Appears
on Sep 27, 2016 at 7:06:56 am

Vegas Pro 13, Windows 10 x64

Very odd problem. I was working on a single mpg file, editing, adjusting, etc. Everything was working fine.
When I went back to the project the next day, the video was blank. In the timeline and preview. The video track was still there, and the splits still showed up, but no video existed and the timeline showed a blank.

Video track is not muted. Audio track is there and still works fine, including all the edits.

I enabled and disabled any video envelopes, thinking maybe I had accidentally applied something. No luck.

I copied the source file to a new name and added it to the project. It played fine.

I closed Vegas, renamed the copy and reopened the project but the video still didn't appear (that was a hope and a prayer thing).

I spent hours trying to find the culprit. I had the idea that to add and identical source video to the project and copy the edits to the new file but I don't no if that is possible. It would be exactly the same file, but I can't find a way to do this.

I haven't been able to find this problem in a search of the forum. Most cases of videos disappearing have to do with video envelopes. And envelopes address an event, and this is broken into multiple events.

Any suggestions?

Strange yes, but the file itself is the problem. Where you got this mpg file from?

Ah, therein lies a story in itself, but I was given the file by a friend. It's an MPEG2 video and the quality is quite poor. It was doing fine as I worked through the edits. It was done a little at a time. But one day I opened up Vegas and the video track was gone.

It's not a disaster, but a lot of time down the drain if I have to re-edit it.

Hi,

Is it online at all?
Is it black, or blank?
What if you place something to a below-track?
Does the working audio come from the same file?
Can you play now that file (it may be crrupted in some way, say it's on an USB drive and unplugged too early?)
What if you move the file away? (Into another directory)
Vegas then asks for a replecement, you can replace it with the same file, or another -say a backup of the original, just to see that the problem is not with the original file...

Best regards

I'll break down my reply. I think I stated most of this in my original message.

1. I'm not clear about what you mean by "online".
2. The video track in the timeline is blank.
3. If I add the file to a new track it plays fine.
4. The working audio is part of the same MPEG2 file.
5. The file plays fine in any number of media players, including Vegas if I add it to a new video track. I think I can safely say it's not a corrupted file.
6. If I move the file or rename it and point Vegas to the renamed file or a copy of the same file, the same problem results -- no video in the edited video track in the timeline.

Obviously this is not something that has a quick fix or that someone has run across before. Just one of those things. I'll just re-edit the video. Since the audio still reflects the edits it will be a bit helpful. Thanks for your suggestions.

Just for future use, is there a way to time stamp the different edits as I go along so I can locate them in the original source later?

Sorry, I did not read carefully.
Media can be offline if Vegas can't open it. Then there's a "media offline" text on the timeline, but this can be covered by other items depending on timilene zoom, so it may be unnoticed.

Just few more hints:
-the events are not muted accidentally? (Not at track level, but at event level - switches/mute)
-opacity of the venets are not 0% accidentally?

Best regards

Tell me, if you restart Vegas, load the project and immediately render it out or render out a small part, does that rendered video comes out looking ok?

Hi David,

Have you tried....

- Save your project to a new name. Close and restart Vegas and open the newly named project.

- Reset Vegas and delete all cached application data. (hold Ctrl+Shift while double left clicking on the desktop icon, then check 'Delete all cached application data'', then left click on 'Yes'.


Best Regards......George

It says Vegas will reset all my Preferences to default values. Is there a way to save the Preferences and reload them afterwards?
