[FFmpeg-user] Better way to merge audio and video? (ffmpeg 1.2.1)

[John Crossman]

Is the following the best I can do? My current wait for process to finish
seems too long.

*ffmpeg -i audio.mp2 -i video.mp4 -qscale 0 -shortest -strict experimental
output.mp4
*

Also, should I replace  '-qscale 0'  with  '-q:v 0'?
