iPad Video Sizing/Format

I need a full screen portrait video like the following:

What should my export settings be in Adobe After Effects. I know that iPad supports h.264 and up to 640x480. But I need it to fill the 1024x768 in portrait mode.

The iPad will happily play 720x1280 h.264 video.

So, in your situation, you should be able to render your video out at a width of 768 pixels, and with a corresponding vertical size that matches your video's aspect ratio correctly.
