Preview not working for pictures/video

My Preview has stopped working properly when trying to preview files in the Explorer or Project Media tabs.
  • For sound, it still works fine (including sound from .avi files)
  • But for any video (stills or moving video, in any file format), the previewed picture/video doesn't appear in the preview window at all - all that happens is that the existing preview picture (from the current timeline pointer) temporarily shrinks by about 50% to the top middle of the preview window for a few seconds (i.e. the normal time of a preview) then returns to fill the preview window. The same happens for Auto-preview or an explicit Start Preview
Once the same files are added to a video track on my project, they then work fine in the project, it's only the previewing that never works... I suspect I've accidentally pressed a key/icon and switched some setting off?

I'm running Vegas 8.0c (build 260) if that makes any difference
 
Preview not working for pictures/video

Not certain if it will work but try opening in Trimmer and then play with the three buttons on the right at the head of this screen. These enable/disable the Preview which can be handy depending on your method of working .

Hope it works - worth a try anyway.

Thank you, that does appear to have fixed it - the Show Video Monitor button on the Trimmer tab seems to have been the difference... very mysterious, as I don't usually use the Trimmer, perhaps there's a keyboard shortcut equivalent which I accidentally pressed? Anyway, thanks again :)

No - what happened is you updated to 8.0c. This is a new "feature" in 8.0c that is ON by default. "Why can I no longer preview video?" is one of the most asked questions as well.
