Comment (by enevills):

 I just gave {{{ -vcodec mpeg4 -qscale 2}}} and it is 1 frame early. Here
 is a screenshot from After Effects CC 2015. http://imgur.com/7w40W8M
 Notice in the bottom right, the playhead is a frame before the waveform

 My command was two frames off. Is the issue with the AAC encoding?

 Same results seem to happen with v3.0.2 and v2.8.6

 Looks like tomorrow I'll be making a 2nd command to offset the video.

 > Do I understand correctly that this is only reproducible with x264 and
 not with {{{-vcodec mpeg4 -qscale 2}}}?
