I've been shooting handheld 720p with the 20mm inside dimly lit basketball gyms.

iMovie 11 stabilization is pretty easy to use, but my concern is that it's cropping to accomplish the stabilization, so it must be doing some upscaling to render back out to 720p. Is it worth the trade off?

edit: i should mention in the sample most clips are not stabilized, i just did a clip here or there. just an example of the type of shooting i do.

iMovie stabalization can work wonders and I'm surprised to see the processing power in such a cheap application. It won't work on everything and sometimes if there is a lot of camera movement (not talking about panning) you will find artifacts creeping in.

You can scale the amount of stabalization and I have yet to see degrdation of image because of it, apart from places where there is so much shake that the software has to "guess" about what's where. In those cases you get a sort of "focus" hunting on parts of the image. In that case it's a question of trade off.
 
Well if it is anything like running the image stabilization in After Effects then it is probably cropping some of the image. From the looks of your video without stabilization the stabilizer probably isn't cropping much. Is it worth the trade off? I think so, makes the shot look nice.

Maybe pick up one of these http://www.amazon.com/CowboyStudio-...1_fkmr0_3?ie=UTF8&qid=1299189934&sr=8-3-fkmr0 It will help you stabilize your shots when in a run an gun situation. They are cheap and they get the job done on a budget.
 
Do you have one of the OIS lenses? What was you f-stop and ISO??
If you are not shooting 720 60p for slo-mo then you would get
better quality shooting 1080 24p and then editing that in a 720p timeline.
Then any cropping and zooming will not be as noticable.

Agreed, shooting in a higher resolution would definitely help to preserve the image quality.
