Hello again.
I've been encoding from dvd to x264 with mencoder. The movie I encoded was NTSC telecined so I removed the telecining using pullup, softskip, and harddup and encoded it to an avi file. I also ripped the subtitle tracks using -sid # -vobsubout file
Then I came across that nice issue mkvmerge has with vfw.
So I riped the raw video stream using mencoder ... -ovc copy -of rawvideo and then used MP4Box -add raw.264 -new movie.mp4 create an mp4 out of it.
The problem is if I use mkvmerge with the vobsubs and the mp4 video the subtitles are out of sync.
If I use --engage allow_avc_in_vfw_mode and mux the avi everything looks fine.
How can i fix the sync of the subtitles? Should I rerip them using some special parameters with mencoder or do I have to manually set a delay factor in mkvmerge? Or did I somehow use MP4Box incorrectly?
I tried doing:
mencoder DVD-SOURCE -oac copy -ovc frameno -of rawvideo -o /dev/null -ofps 24000/1001 -vf pullup,softskip,harddup -sid 0 -vobsubout testsub
but this did not help.
If I now do my video encoding with -of rawvideo instead of using the default avi container and rip the subtitle streams along with it will they be guarenteed to be in sync?
If you encode with -of rawvideo does -oac copy still work to ensure that A/V syncing issues do not occur?
Exactly what parameters (fps, reversing telecine/interlace, etc..) affect subtitle sync.
Will these things also create syncing issues for ripped dvd style chapters that are usable in the mkv format?
