I think that AME uses profile 5 = by default so one has to go in = the
settings and change to 4.1 for the ipad to recognize the = vid.

I forwarded this message to one of = my coworkers who works on the AME presets for iPad. Here's what he = said:



"Evan is not wrong that an iPad may fail to = recognize an H.264 stream encoded at Level 5.

However, if Evan is = referring specifically to AME's iPad presets, his advice is incorrect: = it is not necessary to change the level. The AME presets are built to = Apple's specifications and use Level 3.0 or 4.0, depending on the target = resolution.

If Evan is not referring to the iPad presets and is = simply advising that AME could set the level on H.264 output to 5, then = that's true but the behavior is conditional. AME will load the last = preset used when adding new output items, or when switching formats will = load the preset for that format which most closely matches the source = footage. It's very possible Evan is putting himself in a situation where = AME automatically loads an
H.264 preset that uses Level 5 (though = worth noting that AME does not come with any such presets; the highest = it goes is 4.2; he may have created such a preset = himself).

Regardless, users can assume that the iPad presets in = AME CS6 are safe to use for those devices; we designed them to Apple = specs and tested the output on the devices ourselves.
