How to deal with audio sync when encoding from Variable Frame Rate video?

[Logan9778]

Hey guys,

I've tried about everything I can think of to encode x264 video from a VFR mkv file. Audio sync is always off by about a second or so.

I use MakeMKV to turn the VOB file into MKV's (They're short cartoons). This gives me an MKV with the video, audio, and subs.

I then use DGIndexNV to make .dgi files for frame serving.

I then load the .dgi into AVSPmod to filter it and send it to Simple x264 for encoding.

I can load the avs file into MPC-HC, and it plays perfectly. But after I encode the file, and mux the new x264 video with the old audio file from the DVD, the sound is off.

Never have messed with a VFR video, so I don't know what I'm doing wrong. Help Appreciated!

Here is my mediainfo

and my avs script (avisynth+)

TFM(mode=0,order=1,pp=7,micmatching=0).TDecimate(mode=1) #TFF.
Prefetch(8)

Dgi file shows hybrid interlaced/3:2 pulldown with interlaced opening credits and soft telecine 3:2 main video.



EDIT: Well, I'm trying out TMPGEnc Works 7, and after a few hours of kicking it, I think I finally got it near what I want. I can only set about half the x264 options I want though.

Doesn't seem near as good as what the Community has made.
