It should work on a Captivate without problem.this is awesome! thank you.
-now kind of off topic, but will this work on the SGS Captivate as well, or should I have one of the dev's in their forum answer that for me?
The setup of a boot animation is common for Android devices. I've used boot animations that were initially meant for other phones (HTC EVO, etc.) without problem.
It might look a little odd, however, if you use something meant for a different screen resolution. This is set up for a 480x854 screen (with 240x422 images). Our screens are 480x800. I don't know if the phones would scale or crop the animation, but just a heads up. It sounds like this still looks good, however, on our screens.
