Right so I am trying to render the leftovers from my livestream, the livestream program have me out flash video file(19.794fps, 1280x720, 390kbps) which I then converted to mp4 (25fps, 1280x720, 1409kbps) and wmv (25fps, 1280x720, 7384kbps) files.
So I started working on the output files one at time hoping I would get different results, but ended up with the same results.
I've had CCCP for the longest time, even before actually installing Vegas itself, and I could render 2 mainconcept files before this one just fine. Although with this one, Vegas wouldnt even recognice the mp4 version before installing quicktime.
And no, I havent updated any drivers recently. I know its not a driver thing because know what? If it was a driver thing, you would not be seeing that flicker, if your drivers are installed correctly.
