Hi, I am rendering video using sony vegas 11 and after the render, I have these flashes and glitches in the video. Each time I render, they are in a different spot. Sometimes there are multiple glitches, sometimes as few as one. Sometimes it looks like the video was on tape that had a bend in it. I have tried to render the same video about 9 or 10 times. The glitches are never in the same place twice but I have zero good renders. Any ideas as to what may be causing this?
