 Compare with the output for a video just created with ffmpeg:

 {{{
 |  + Video track
 |   + Pixel width: 320
 |   + Pixel height: 240
 |   + Interlaced: 2
 |   + Display width: 8
 |   + Display height: 3
 |   + Display unit: 3 (aspect ratio)
 |  + Codec's private data: size 46 (H.264 profile: High @L1.3)
 }}}

 This video does not contain any aspect ratio information. Therefore,
 ffmpeg does not print it.

 The same probably applies to the MOV file, but I do not know the tools to
 examine it.
