Body: <p>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". </p>
  
  <p>Error Message:</p>
  
  <blockquote>
    <p>Video will be resized from 1280x720(1.00PAR) to 176x120(1.21PAR) to meet format constraints.</p>
  </blockquote>
  
  <p>Anyone know of a fix to this? Looks like my encoder is MainConcept MP4 Video. I'm using CS6. Thanks!</p>

Comments.Text: Could you elaborate on how you are choosing the container and video codec? An overview of the steps you're taking would help answer the question. Because when I choose the `H264` output module in the After Effects renderer I get a `.mp4` file with no PAR (Pixel Aspect Ratio) errors.

  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](http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC) is a wikipedia entry which contains a table on h.264 level dimension constraints.
