Maximum safe AC3 bitrate
on May 16, 2013 at 11:24:28 pm

Advice on the maximum video bitrate someone can safely use for encoding DVDs is fairly plentiful, but it seems that those recommendations don't mention a max audio AC3 bitrate.

Based on advice I've seen, for the video component I will probably shoot for 7 mbps CBR. But in conjunction with that, is there a max audio bitrate I shouldn't exceed?

Target audience could include less tech-savvy or third-world country users, so broad compatibility is desirable.

Thanks in advance.

I was always told that we need to consider how much space we have available for the audio and have always set my audio for 256, although a lot of encoders automatically encode at 196. My audio settings give really nice sounding audio and I never have problems with the playing of my DVD's.
