in windows movie maker just go to save to my computer and its a automatic re formating and thats all you got to do if you use

sony Vegas later on you have to go to file then render that take a while to do though
@ last step of wmm - save/publish to computer, wmm displays the options

- Best quality for pc playback in wmv (auto)

- compress to xx kb (seldom chosen)

- Other settings:

---%26gt; avi (saves in big files - not soooo good for youTube)

---%26gt; wmv quality (Hidef, Dvd, vhs, etc depending on final destination)



*depending on ur choice, wmm displays:

on bottom left: the format- wmv or avi, resolution/display size (choose higher- it's better)

on bottom right: the est. movie file size - youTube limit is still 100mb? choose quality nearest 100mb
