currently i have a 16:9 edit in my timeline, once exported and placed on a DVD i have this annoying line. I want to export an uncompressed self contained film and then re import into a timeline as a single 16:9 movie not an edit with a thousand shots as now. Once i have a self contained film in the timeline i can add a mask. currently i would have to add a mask to each individual shot. The problem is that at the moment when i export to quicktime it changes the film into a 4:3 image. When i re import that image into my 16:9 timeline it remains 4:3.
