Comment (by Francesco Bucciantini):

 Found the culprit. It's the mute audio that makes it going on and on
 forever. Basically BlankClip() generates a mute audio, but length=0 makes
 it go on forever. Now, this shouldn't really matter 'cause

 1) The video is 2 frames long anyway (frame 0 and frame 1)
 2) Once it goes through AudioDub() it should really follow the video and
 NOT keep going forever and ever
 3) The container is .mxf for which audio and video must always be of the
 same length, so ffmpeg shouldn't really be doing what it's doing
