user3605: I'm trying to export a composition from Adobe After Effects. My Comp is 1280x720, and ideally I'd export with an mp4 container, and h264 video codec. Problem is, After Effects is giving me a PAR error, telling me the video will be resized "to meet format contraints". 
Error Message:

Video will be resized from 1280x720(1.00PAR) to 176x120(1.21PAR) to meet format constraints.

Anyone know of a fix to this? Looks like my encoder is MainConcept MP4 Video. I'm using CS6. Thanks!

user2836: It sounds like you are using a trial version of an encoder that imposes limitations on the size it will export based on the severe down-scaling that it is imposing.

user3592: In AE's "output module settings", with the format set to h.264, click "format options".  Under the "video" tab, make sure "Level" is set to 5.1.
Here is a wikipedia entry which contains a table on h.264 level dimension constraints.
