I've done nothing with video except play them from YouTube.
I've noticed that YouTube separates HD1080 video from the audio tracks,
meaning I can't just download the HD1080 vid and watch it comfortably
using my USB sound card. But I can download the HD1080 vid and the audio
track separately.
Ideas? Thanks.
ffmpeg and avconv can do the Job fo you.
for example:

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!
You can also do it in realtime, so you don't have to produce a new video
file, using mplayer.
Assuming the video file is called video.mp4 and the audio file is called
audio.mp3 you can simply use (assuming you want it to play through jack,
otherwise simply ignore the '-ao jack' argument):
mplayer video.mp4 -audiofile audio.mp3 -ao jack
Sometimes the audio doesn't sync up with the video, and then you can
'resync' using '+' ansd '-' keys while playing in order to 'move' the
audio +/-100ms.
I hope this helps.
Kind regards
