Ok, you forgot the Not in your previous message.
Thus, could you post the mediainfo analysis from one that does pass ?

The only difference I see is the video codec ; mpeg-2 for the one having problems, AVC for the other. This is strange, I guess you should be able to get mpeg-2 with LPCM in 5.1.

Can be that the 25 fps video is auto re-encoded by MultiAVCHD into 24 or 23.976 fps with approx. 4% slowdown keeping the same frames. Would mean audio has to be re-encoded to (stretched).

Edit: Maybe you can post MediaInfo of the converted file (which source has the 25 fps mpeg2 video)?

Interesting remark, I hadn't thought of this.
IIRC, to avoid re-encoding, the menu has to be set to Pal24 (or Pal). Otherwise, if set to Ntsc, Pal videos are re-encoded.
MultiAVCHD can also do the opposite : accelerate 24 fps to 25 if Pal speed-up is ticked in settings (I guess it has no effect if menu is set to Ntsc).

Thank you detroit1, but actually I was asking MediaInfo about your file that didn't pass-thru pcm. Please both source and MultiAVCHD-result.

A heads up to anyone using the subtitle creator in multiAVCHD (and that goes for easySUP and goSUP), the default font Trebuchet MS doesn't support music notes (♪) and probably other symbols.
You may want to go with Arial Bold or Tahoma instead.

Edit: The font limitation may have been restricted to WinXP. Since upgrading my system, Trebuchet works fine for music notes. In fact it is able to italicize them when Arial can't.

Thanks for the remark DoctorM.
The increased reauthored BD issue has been dealt with?

Speaking of subtitles, I've been going crazy trying to add an SRT subtitle file to a BD. No matter what I tried I kept getting sync problems.

Completely out of ideas, I demuxed the subs from the m2ts created by multiAVCHD and compared it to the original text subs.
By the end of the movie the SUP file is 8 seconds off from the original SRT file!
How is that even possible?

Test easySUP and it works correctly. I did not test goSUP. Anyway, bug ho! Create the SUP file separately first to avoid problems.

Did the subtitles concern 24 fps video? EasySup has a 24 fps bug.

Everything I checked shows the movie as 23.976 (left EasySup's setting alone and multiAVCHD doesn't give you an fps option).

What is EasySup's bug so I know to keep an eye out for it? Why should the frame rate matter if the subtitles are by timecode?

Still, multiAVCHD's subtitle creation acted differently than EasySup's.

When you set ouput to 24 fps you'll get 23.976 fps SUP file. You can check this by importing into tsMuxer.

Maybe that SUP timing (or it's interpretation of software/player) does not depend solely on timecodes. Maybe framenumbers are used along the way (or at the end in authoring phase)?
If you open a subtitle file in tsMuxer standalone, the framerate is displayed. Maybe just a header, I don't know. Anyways, in tsMuxer, when you select the subtitle, in "General track options" you have the option to "Bind to video FPS". This comes in handy when the subs have different fps than videostream, but the timings are correct.

But better way to deal with the 24 fps bug is to correct fps with BDSup2Sub, or create SUP from text with eg. SubtitleEdit.

I do a lot of text-editing of subs and thus always create them before importing into authoring software.

I usually edit in SubtitleWorkshop, but I've never seen a way to output SUP format from that (not that it may not). I'll check out SubtitleEdit.

Btw, tested goSUP and found it to be better than EasySUP. The latter was more aggressive with the safe zone than it should have been and the look seemed worse.
Most importantly, EasySUP doesn't seem to have the frame rate problem either.

Since multiAVCHD doesn't give you a place to set the framerate, it probably just read the framerate from the movie wrong.
I find it difficult to believe it is always wrong even though though it had problems the first time I used it.
Pre-rendering the subs with a manual fps is the answer. I just don't know that it is ALWAYS necessary.

Yes, even apart from the 24 framerate bug, I encountered several issuess with MultiAVCHD in some cases. It's generally a great tool, but sometimes does things it's own way, my guess. And pre-rendering is indeed the way to go. My experience is, that if correctly pre-encoded/-muxed files are fed into MultiAVCHD, it does a great job always.
