[FFmpeg-user] mpeg2 filesize reduction: reduce video, enhance audio, codec selection

[Beeblebrox]

Answering some of my own questions here,

For Q_#4, I could have used ffmpeg
ffmpeg -i concat:M2U00210.MPG\|M2U00211.MPG\|M2U00212.MPG\| -c copy
video1.mpg
but is there any difference in resulting quality vs "cat"?

Final ffmpeg command looks a little better:
"$ ffmpeg -i video1.mpg -c:a libfaac 'volume=2' -c:v libx264 -preset slow
-crf 28 video1-out.mp4"
Is libfaac the right choice? Video-out as mp4 correct?

Regards.
