I just thought that some active applications can be changing behaviour of the Sony Vegas. And the antivirus was the first suspition.

But… I’ve got the same here. Checked my Project again… and now Nod32 exclusions didn’t help. So… I remembered that I’ve been closing bunch of programs before adding Sony Vegas to the Exclusions list.

Now I did the same, and closed programs one by one. When I closed “UPS Assistant” levels stopped moving back to zero. O.o. Shocked. That’s it. When I leave it running, the slider moves to zero, when I close it, everything works just fine in Vegas.

My guess now is, that the “UPS Assistant”‘s code is checking every 3 seconds for some information using the non-safe methods and somehow updates wrong GUI element Id.

Now, if you don’t even have this program running by any chance, try closing any apps that are in Windows Tray. Maybe you’ll find your 49.9% bastard 😉

Good luck!

I think I’ve got it. It’s freaking NOD32 antivirus. Added Sony Vegas directory to the Exclusion list and it’s not moving to 0 anymore! I bet you have it too… Here is image of Advanced Settings of NOD32:

Same here, only difference is video levels fall down (drop) to 0 (zero) percent. Every 1-4 seconds. Nothing I’ve tried helps. Only solution is to use Sony Vegas Movie Studio HD 11. That way there are NO levels to move to 0. And no useful features too…

It happens without any plugins…

Windows 7, 64 bit. Happens on Vegas 9, 10 or 11. Reinstalling never helps.
