Hi Jennifer,
Later versions of Quicktime misreport the current size of videos in the 844/X codec. So don't worry about that. What version of Quicktime are you using?
You don't want to export as 720*480 from 844/X. That would do the scaling before deinterlacing that Floh warned about. As normal, Floh is right on the money here.
The simplest solution would be to invest in some compression software, like
Sorenson Squeeze. It's $500, so a bit pricey if you never do other compression. But it will do the cropping and encoding for you.
Do you have After Effects? I could type up a quick workflow for that.
Cheers,
Ben
