When I encode a video using H.264 and make it larger than 720 x 450 the video will not play on an iOS device.
Is this normal?
Is there a size limitation on iOS devices when playing them in jwplayer?

I have seen instances where "digital copies" of purchased movies are played on an iOS device that are clearly larger than 720 x 450
We have instructional videos that rely heavily on being high resolution because of clarity and we want them to also be viewable on an iPad. We also do not want to have multiple resolutions of the same video. We are tying to find that "sweet spot" between clarity, mobility and efficiency(production).

Are the larger files that are played on the iPad played in the browser on the iPad though, mobile Safari, or is this through the built in video player on the iPad?

we tested them in safari (jwplayer) & the built in Quicktime player and they both fail.

Ah, got it. If they both fail, then it has to do with the resolution.

I'm looking for an official statement on the maximum resolution supported on ioS to ensure that that is the issue and not something else happening while encoding.

The iPhone can play MOV and MPEG4 videos with a maximum size of 640×480 and only allows the Base Profile for H.264 (See Apple’s own instructions for the specifics). If your desired video is bigger than that, please read the instructions below for how to adjust the code to use hi-res videos whilst keeping iPhone compatibility
iOS has a limitation in this area. It needs to be smaller.
