__What interleave settings should I use to mux my AC3 in NanDub? This is by far the most difficult task for some people. It seems as though we can't have a magic set of numbers that will work for everyone. This is mostly trial and error in order to find the right values. So below is a few common interleave settings for muxing AC3 (preferably using NanDub)-
code:--------------------------------------------------------------------------------
90ms/90ms
120ms/120ms
500ms/128ms
500ms/64ms
160ms/160ms (Works well for 5.1 384kbps)
128ms/128ms (Works well for 5.1 448kbps)
96ms/96ms
80ms/80ms (Works well for 2.0 192kbps)
64ms/64ms
250ms/64ms
160ms/60ms
160ms/2frames
500ms/3frames --------------------------------------------------------------------------------
First value above is for preload. Some users have reported choppy playback if using the NanDub default 500/1frame setting. There has been some discussion in the forums and the general consensus for most users is that the values must be multiples of 32(i.e. 64, 96 or 128). One of the values above should work but it will take some patience testing them.
Also worth noting, Acaila kindly pointed out that certain interleave values above might only work for a specific AC3 bitrate. A 448kbps AC3 seems to work nicely with a 64ms/64ms setting but audio drop outs might occur with this setting. I tested 96ms/96ms and 128ms/128ms and they both worked very well on a Fortissmo II and TB Santa Cruz card. For a 384kbps AC3, try an interleave of 160ms/160ms.
__What effects might I see if I've used the wrong interleave values? The most common problem seen if wrong interleave values were used is to have jerky pan & scans during playback. Watch a movie closely when the camera pans from left to right or vice versa, it should be very smooth. An easy way to tell is to watch your ripped AVI without audio and then watch the same clip after you have muxed the AC3, you should not see any difference in regards to smooth playback.
As mentioned above, the wrong interleave settings could cause the audio to stutter during high action scenes(ie. Drop outs as mentioned above).
If your settings are really out of whack then you might not hear any sound at all.
