Audio encoding HELP!

[gurabli]

When using the AC3 file for the final movie, just mux, what should be selected in the audio option?
1XAC3 ?
What does the "Frames" mean in the roll-down section?
What to select from 1 to 30? What are the differences?

HELP!:confused:

[TheWEF]

1xAC3, 1 Frame interleave interval is correct (default, choose the same in the audio encoding window later on) .

Can You help me to understand what Frames interval means?
Is there a guide somewhere?

in an avi (= audio video interleave) audio data is interleaved (interwoven) with the video data.

x frames is the interval for audio interleaving (e.g. 1Frame @ 25fps , 1000/25 = 40ms).

the smaller the interval the more file overhead, but high intervals often cause playback problems.
