Converting .MOV files

Tehre are a few ways you can shorten the d'load time for a movie on a web site. Basically you want to do whatever you can to drop file size but maintain quality.
You may need some sort of video editor or something similar. Quicktime Pro will let you do some manipulation as will Cleaner.
One thing to so is make sure the image is only 320x240. Then maybe drop the frame rate back to 15 or 20.
Size is also determined by the file type. QuickTIme movies (.mov) are good tho pretty big. MPEG's (.mpg) are usually smaller as are RealVideo (.rm) files, though .rm files tend to look pretty bad.
Or you can try a WIndows Media (.wm) file and see if that helps.
I'm not familiar with .asf files so I'm no help there.

D'load time can seem shorter if you set the files up to stream. Then you don't have to wait so much before the show starts.
I hope this helps.
