Heya. So I've been capturing a fair amount of BF3 gameplay lately, with the intention of editing it then uploading it to my youtube channel. However, I've run into a bit of a problem with Sony Vegas. It seems, when I add text to the video, the playback will suddenly go all choppy and black and jerky, like someone's turning a TV on and off really fast. it only happens when text is being displayed during the video It happens alot when a lot of text (different video tracks containing different texts) are displayed at the same time, to the extent where the video is unrecogniseable. Just wondering If anybody else had the same problem, or if there's something I can do to fix it.
