I just got a new mba and have been editing my videos via iMovie for Youtube. I was previously using Pinnacle on my ipad and it was MUCH MUCH faster to upload a HD movie 720p to YouTube. (about 15 minutes for 720p vids) What is the best way to upload HD 720p movies to YouTube with a video made in imovie? Should I export it first and use another program to upload to YouTube? Also, if I should export first what are the best settings I can use for HD quality on YouTube that give me the fastest upload speeds? Thx in advance.
