Problem when/after muxing M2TS file

[architectofpain]

Hello.

I recently ripped a Blu-ray disc using AnyDVD HD as I wanted to sync a different audio track to it. I demuxed the disc using both ClownBD and TsMuxer (after I saw this problem). I got the tracks synced up, and muxed the files into an m2ts, again using TsMuxer.

The source files play properly, and the video looks fine but after I mux, the resulting m2ts plays back with a lot of glitches. I've tried it in MPC-HC as well as Windows Media Player.

I'm curious if anyone could tell me where I perhaps went wrong, and what I could do to rectify it?

Regards.

Glitches? Exactly how? How often?

But compare the frame rate/fps in the source m2ts with the new m2ts using Mediainfo. Are they same?

Change to view->text in mediainfo and copy everything and post here also so we can check and see if we can find anything.

I don't know if there's a technical term but it looks like the image is kind of 'breaking up' or freezing. They are pretty consistent.

I'll remux, check the frame rate and post that here.

Thank you!

Nope. I have no idea.

[architectofpain]

I did think of one thing. The audio track that I muxed in there was something I'd first stretched in Audacity (it came from a DVD that had a different frame rate to the BD) and then synced to the BD in Sony Vegas. Could something from either of those steps have perhaps triggered the glitchy video?

[Baldrick]

I don't think the audio will cause playback freezes.

Maybe try reauthor with something else. But I don't know anything as simple as tsmuxer.

If you don't need a m2ts can you try make a mkv with mkvtoolnix.

[architectofpain]

I tried to create an mkv with mkvtoolnix last night after posting that, and it too caused the same freezes.

If it's not the audio track, it must be either something in the ripping process or a problem with the BD itself. I doubt it is the BD since playback of the original files (in my PC, PS4 and blu-ray player) has been flawless.

[Baldrick]

If you just try remux with another audio track does it play ok then?

[architectofpain]

I've remuxed it without my newly synced audio and it still plays with glitches.

Would converting the audio from wav to ac3 perhaps make any difference?

[Baldrick]

I doubt that.

When you load the source M2TS into TSMuxer, is the "Remove pulldown" feature available? If so, enable it, and try demuxing and/or remuxing this way.

[PuzZLeR]

Posting back to say that I was also going to recommend that, using TSMuxer from my last post, you disable "Continually insert SPS/PPS" but that would break blu-ray compatibility if going back. Pulldown is only really necessary for SD at that fps (which would be strange if it was encoded as such in the first place).

Remove pulldown is greyed out. I wonder if disabling "Continually insert SPS/PPS" would have any effect if I did not plan on writing the resulting m2ts to a BD-R. I don't actually have a blu-ray writer so I was planning to view it via an external media player in the meantime.

I'm believing that there are blu-ray properties in your M2TS file that are creating issues with non-blu-ray playback, such as delimiters, time codes, etc. Yes, try different combos with SPS/PPS and SEI/VUI timing and see what happens. (Hang on to your source for now, just in case.)

Thank you for the post. I believe that is what fixed it. I made sure "Continually insert SPS/PPS" was unticked and "Do not change SEI/VUI data" was selected and that seems to have fixed it. I will watch the video carefully when I get a chance, to make sure though.

Thanks to everyone who offered their expertise with this issue.

[PuzZLeR]

Glad, at least for now, that it's working.

Many blu-ray elements, normally for blu-ray playback on the disc and hardware, such as deliminters, small GOPs, timing codes, pulldown, or even levels, etc, are not meant for playback on other means, or not decoded properly by other playback software. Sometimes such properties need removal, or a re-encoding of the stream if they can't be removed.

I think I understand that. From the sound of that, even if I was able to burn this to a BD-R and play it I might still have needed to go through those initial steps after demuxing.

Thanks again.
