Thanks, I'll gave it a try.

No, actually, I use ffmpeg most often. What do you use?

Hmm... that's actually the next question I'll ask. 

Since the video frame rate has been increased from 20 to 25, shouldn't we
increase the audio frame rate (or something) as well? I know if the frame
rate is not changed, we can dump the audio them mux it back, but what if the
frame rate is changed?

thanks
