I have been using FCX HD to make movies, but I am attempting to upload a movie now to blogger and YouTube. I have a video that's just under five minutes but tops out at about 1.75 MB -- apparently too big for either of these sites. Obviously lots of movies on YouTube are longer than five minutes, so I'm obviously exporting it as too large a file. Which export format or procedure is going to give me the most manageable online file with the best quality? Thanks for any advice.
