M2TS fine, MKV not so fine.

[sixleaf]

Hi (brand new here so im doing my best to stick to the rules)

Trying to simply take video and main audio track from a m2ts (used anydvdhd to grab it) and put it into an mkv for more media player compatibilty etc. No recoding. I did this once with a VC-1 Bluray and it went perfectly - tsmuxer to split out the 2 tracks and then mkvmerge to mkv and it plays 100% perfect.

Problem is the only other bluray i own is h264, and tho it demuxes fine into a .264 when it comes out the other side of mkvmerge the video and audio drop in and out of sync. I *think* the video speeds up and slows down momentarily every now and then and thats what causes it.

EDIT: Forgot - In mkvmerge it says it cant tell fps of the 264 stream. I tried using both "23.976" and "24000/1001" but no help.

I know that the source is fine cos i played the m2ts back start to finish in powerdvd and its all peachy.

Am i doing something really stupid? (Oh, tried playback in both VLC and KMPlayer)

Cheers!

bump? Ever solve this problem? I have the same problem. I've tried a few things but to no avail. I'm pretty certain the problem comes from the muxing since if I remux the files to a .ts file using tsmuxer, there are no audio video syncs. I don't like this solution since .ts doesn't support the subtitles I can play. The problem is also system and player independent (tried on mythtv in linux and media portal in windows and got the same problems).

Any help would be appreciated.

I don't have a solution for you but I can tell you this that TsMuxer always says it can't get fps info on h.264 in my experience, that is normal AFAIK

Also they say that PDVD ignores frame overlap so it plays video just fine that other player can't

Are you using the very latest TsMuxer?, it fixes overlapped frames

Thanks for the reply. What I meant to say is that when muxing with tsmuxer that there are no a/v sync issues however when I use mkvmerge then there are. I'd prefer to use mkv since I can use subtitles.

Are you saying you can't use TsMuxer and watch your movies w/ subtitles in PDVD?

Are you playing .m2ts files or Blu Ray compliant folder structure ISO's?

No. That is not what I'm saying. Like the original poster I am "Trying to simply take video and main audio track from a m2ts (used anydvdhd to grab it) and put it into an mkv for more media player compatibilty etc. No recoding."

When I mux into the mkv container, I'm getting audio video sync issues with certain movies. I remuxed into a ts container to check whether the problem was in the original demuxing of the movie or if it arose from muxing into the mkv container. Since the ts played fine (without audio-video sync issues), I think the problem is in the muxing into the mkv container.

You just wrote, "I'd prefer to use mkv since I can use subtitles"????

You don't need to use mkv to have subtitles
