Thanks, I'll try that, too. I just finished doing it using Kdenlive 
(took about 30 minutes to render on this 2.4GHz i7!) but it has an audio 
glitch toward the end.

Well, ffmpeg was a LOT faster. Also produced a smaller final MP4 (250MB 
vs 266).

Still has the audio glitch towards the end, though. Let's listen to the 
audio-only track, maybe the glitch is in it. Ah, yes, the glitch is in 
the audio track. Tried downloading some other versions of the audio 
track, they all have the glitch.

Oh, well! I have a decent combined video. Thanks for the help!
