Comment (by Cigaes):

 You can use the {{{setsar}}} filter to for the aspect ratio for the stream
 that does not have it.

 It would be interesting to know how you arrived there. You should post the
 exact command line that you used to produce {{{test3.mov}}}, along with
 its full output (at default log level, that should be enough).
