ok so i've been working on a video i would like to upload...the video will sometimes freeze in the exact same 2 places, and i switched out clips to see if that was the problem...but it wasn't, b/c it still freezes in the EXACT same spot of the song...and everytime i try to upload this video to youtube, iMovie "quits unexpectedly" after like a minute of trying to upload it, i don't know if there is a bug or something like that...does anyone know why it keeps quitting? PLEASE HELP...it's sooo annoying! and i have no idea what to do!!!
