Video compression settings for iPad 2?

I'm trying to encode video for the iPad 2.

I'm using 1280 x 720 a 5mbps and it seems to be working well. The source footage is 1920 x 1080 HD.

I'm now trying to put some PAL 720x576 files on the iPad 2 and it won't let me.

Where can I find out which video sizes the iPad supports?

I know 1280 x 720p is one of them. Anything else?

Thanks for that..

Somewhere below it says that the data rate needs to be no more than 2.5Mbps. As a test I rendered something out at 20 Mbps and it worked.

I find it strange that it worked and that both the iPad and iPhone 4 played it back flawlessly.. Would you know if possibly iTunes is optimizing it somehow?

Is 20 Mbps even possible on an iPad / iPhone? This is almost Blue Ray Quality I think. Well 35Mbps is Blue Ray.

iPad & Apple TV can play the following video formats:

•H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats

•MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats

•Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format

Is that what it does are you sure?

All I did was encode a 20Mbps file and synced it to the iPad 2. There
were no alerts telling me its downconverting.

I'd really like to know if it is downconverting though..
