user5484: I have a ~70mb (3 minutes long) m4v video that I need to get to a much more reasonable file size for playing on a site that will primarily be accessed via iPad.
I don't know if it matters, but the video will need to play automatically upon page load.
I've read through a few tutorials for doing this with Quicktime, however I think I'm missing something..
From the Export pop-up menu, there should seemingly be an option to choose "Movie to QuickTime Movie." I have only 480p and iPod/iPhone/iPad options(which I believe would result in a viewing frame that is too small).
How can I proceed with web-optimizing this file in Quicktime? (Or is there a better solution? I tried Sorenson Squeeze, but that had a large watermark..)

user2598: To add on to AJ's answer, Vimeo has a dedicated page on their preferred compression settings; Youtube has the same.
Check these out for some more specific information on which bitrate/codec to choose!

user1950: You need Quicktime 7 pro to get the full export options. Quicktime as it currently stands is a gutted shell of its former self. Can I suggest you use mpeg streamclip. Free, very widely used (by many professionals too) and a great tool for transcoding. 
That is unless you're handy with the command line, in which case you want ffmpeg.
