Avi lossless file
from mediainfo

Alignment : Aligned on interleaves
Interleave, duration : 42 ms (1.00 video frame)
Interleave, preload duratio : 500 ms

It is my understanding that 42ms is how long each frame is. Does this in any way delay the audio?

When i encode my avi to hevc using staxrip - no delay at all in the audio edit section - the new encoded file audio is somewhat 1 frame behind the avi file when comparing both audios waveform on virtualdub. The new file, if i use vdub to delay the audio by 42ms then the audio would match the avi file.

Therefore it got me thinking 42ms interleave duration does something. If not is there a reason staxrip is delaying the audio without my permission?
