Brian hit the nail on the head with this one.
I use Compressor to encode most of videos that I post for client preview. A trick that I use if I’m pressed for time and need a quick and simple solution is found in QuickTime Pro.
Command+Option+S
This will compress for email. I doesn’t give you any control other than Small, Medium, or Large. As you switch you’ll see the changes QT makes in frame size, framerate, audio sampling rate, etc. Be aware of your needs and the adjustments that QT makes to get the estimated file size.
After you make the selection QT will compress and add it to an attachment in Mail. Drag this attached video the the desktop or other folder.
Not sure if this would be useful to you though. Good for quick client previews, but I doubt I’d use it for a vid that’s going to remain on a site.
