Comment (by seahorse41):

 No that does not solve the problem.
 {{{
 > ffmpeg -i 20150204_1037_beaverDam7_rec_5472.MOV -c:v h264 -s 640x360
 -c:a mp2 test2-ea-1.mov
 > ffmpeg -i test2-ea-1.mov -ss 12 -t 8 -c copy test2-ea-2.mov
 }}}

 The aud/vid sync goes bad in the second file: test2-ea-2.mov

 Even if that solved the problem, it would lose audio quality if I re-
 encoded the audio. I would end up remapping later the original audio track
 back in to whatever re-encoded video I made.
