Hi, so I made a video in hd-720p on imovie. I did this because I didn't want my video to have black lines on it, however now I am not sure how to export the video to get full quality settings. When I exported to divx it came out slightly faster than the original video and glitching, and when i uploaed that to Youtube, you could see black lines on the top and bottom of the video again, which i dont want. Is there any way I can make this video fullscreen without seeing the black pillars, or export it normally without Youtube adding the black pillars and getting full quality? Sorry if this question is hard to understand. I'll appreciate an help, please, thank you.
