I have this same question. I used screen recording software and the video is saved as .mov. I try uploading it to youtube but its too long. I've spent the last two long unfulfilling hours researching this forum and other places to no avail. The MPEG software doesn't work...makes the video look very strange and turns the images sideways, pretty useless. I tried using Parallels and transfered the file over to use PC software but crappy windows doesn't recognize .mov files. So frustrating. All I wanna do is upload my #$#$! video! I also tried using imovie but omg its so confusing idk what the hell im doing. Why cant this just be easy...its Mac..its supposed to be easier.
