multiAVCHD makes weird things with subtitles! Need help!

[ghostp]

Hello folks,

I'm standing in front of a problem which finding a solution for it costs me already hours without success.

Here is what happened.

1) I have loaded a bluray movie (fps 23,976) into multiAVCHD
2) I have added some subtitles (same fps)
3) I have reauthored everything and burned the disk with imgburn

So far, after playing the movie on my standalone bluray-player the subtitles somehow are out of sync, means they're to late. It seams like multiAVCHD resync the subtitles.

Any ideas?

And they are in sync before you author?

You can also try author with bdtoavchd or avchdcoder or bdrebuilder.

Hello and thank you for our answer!

Yes, the subtitles are in sync before I author! That is weird!

I would like to author them in bdrebuilder but I don't know how to add them! The subtitles are in srt, idx or sub

Did you test the subtitles first to see if they were in sync before you burned the video?I have been using multiavchd for years and it never puts my subs out of sync,it doesn't do any resyncing on subs,subs don't have fps so it could be the original sub is out of sync to begin with.

Believe me, it's weird. I have extracted the subtitle into idx, sub and srt and did two tests as follow:

1) Author srt with multiAVCHD --> Subtitles out of sync
then
2) Author srt with DVDFab --> sync is perfect

The thing is though, I'd like to Author it with multiAVCHD because I can change the height of the subtitle which can't be done in DVDFab.

I use MultiAVCHD, I've had some weird errors over the years, and I too have had issues with subtitles, from time to time and for no apparent reason. Sometimes (rarely) out of sync, sometimes advanced subtitles is chosen but it defaults to quick processing (still looks ok), sometimes they don't work at all (due to error in .srt, like, an empty line or weird character).

Are you compressing video or audio using MultiAVCHD or are they already compressed to proper size? Tried using FFms2 in settings? I had sync issues using (an updated) FFms2 and importing HEVC-movies - which I can't blame on MultiAVCHD as it is too old to properly support HEVC. (hevc sync issue disappeared after I disabled audio processing for the film)
But for other files FFms2 have worked better than Directshow. I have no clue why, but at the moment I'm using a virtualized Windows 10 installation.

One solution I've tried is SubtitleEdit and export as bluray sup subtitles. I play them and the film in a player supporting .sup-subtitles to make sure they are in sync and look proper. I then import the subs to MultiAVCHD and create the menus.

SubtitleEdit will allow you to change font and size when creating sup subtitles. http://www.nikse.dk/subtitleedit/
