When I import a video and put it on the timeline, and the audio once i export the video and watch it, the top and bottom of the video are cut out, and when i go to safe margins and try to fit it in them as best as possible it leaves spaces on the right and left sides with nothing i can do about it, is there anyway to have it automatically fit to the margins? Also I plan to Compress the video before i export it, its rendering now, what woudl be the best format to compress it in? Thanks Alot
