I want to use Windows Movie Maker to make a youtube video...? HELP!?

well i have the same problem then i figured it out if its a file that big its either not going to work or it takes a while because i remember when i tried to use it there was 1 that was 49,000mb and it took like 5 hours just wait a awhile or what u could do is right before u go to bed leave the computer on and do it and then when u gt up the next morning and check it if it doesn't move than try contacting windows
