Can open/edit h264 in Movie Studio 6, not 8 Pro? MrEdit wrote on 12/15/2008, 7:26 PM ...i don't get it source is a .TS file converted to h264 mp4 using ArcSoft Media Converter. Files open and editable in Movie Studio 6.0b. In 8 pro "vegas could not open any of the files" or whatever. Import doesn't work. What's the deal? Have Quicktime Pro installed. Back to post
