If I am not wrong, Apple imposes a limit of 200 mb on the size applications can have. I am planning to include some videos in one of my apps and the videos include several large segments of 10 or 20 minutes.

If I encode these videos for ipad (720p) and for iPhone 4 (1024x768) do you guys have an idea of how much space a minute using one of these encodings will consume? 

In other words: how many minutes will I be able to store in (lets say) 190 MB for iPad and for iPhone 4?

on the iPhone 4 I have to consider the case of packing the application with both formats (3GS/3G - 480x320) and iphone 4 (1024x768).

Consider two apps: one for iPad and another one for iPhone.

thanks.
