1.8.10 Generating Multiple Invalid Timecodes

[ronblade]

While investigating a remuxing issue with 1.8.10, I have also discovered that all of the Blu Ray MKV I have made with 1.8.10 seem to have multiple, sometimes hundreds of invalid timecodes.

The issue is only made clear when attempting to remux a MakeMKV 1.8.10 file -- MakeMKV displays no notice that anything has gone awry during the initial extraction. Upon remuxing the same file with MakeMKV, I seem to be getting the following notice of timecode errors:

=============

If I use 1.8.7 for the initial MKV extraction, the remuxing displays no such errors, even when using 1.8.10 for the remuxing. It appears that 1.8.10 has introduced this issue when it creates MKVs from Blu Ray discs.

Thank you to everyone for your help on this!

Can you please do the following:
- Create MKV file (001.mkv) from the disc with 1.8.7
- Create MKV file (002.mkv) from the disc with 1.8.10
- Using mkvtoolnix trim both files to about 3 minutes - you'll get 001_small.mkv and 002_small.mkv .
- Confirm that "small" MKV files still exhibit the issues with 1.8.10 - pgs remuxing fails, and timecodes re invalid on 002_small.mkv but valid on 001_small.mkv

Then upload 001_small and 002_small to dropbox and send the link to support@makemkv.com .

Also, please do a following quick test - try processing the 002.mkv with 1.8.10, you'll get "invalid timecodes" message. Then process the produced file again with 1.8.10 - would you get anything?

[ronblade]

Thanks for your quick reply! I have just emailed you the links to the two trimmed files, which exhibit the behaviors I have described.

As for processing the "bad" file a second time through 1.8.10, yes, it seems to report the timecode errors every time.

If it matters, I use the OSX version of MakeMKV for all of my processing, though I have a Windows machine that I can test on in a pinch.

Thank you for continuing to do such excellent work on this amazing piece of software.

I just installed a new blu ray drive in my Mac system and I am getting the same timecode errors with 1.8.10. Still wondering if I am the only one experiencing this issue.

[Woodstock]

A thought - at version 1.8.7, I remember the display of AV sync messages was disabled by default. In 1.8.10, they are enabled by default. Since I turned them on many versions before that (just after I learned about them), that setting has stayed enabled since then. I only noticed the change in default when I installed MakeMKV on a different machine.

On your 1.8.7 installation, go to the Preferences menu, General tab, and make sure that "Show AV synchronization messages" is checked. Then the two installations will be "in sync", as far as error and information messages are concerned.

That would be the true test of whether or not the messages really are JUST because of the version change.

[ronblade]

Thanks for suggesting this, Woodstock, but I have had "show AV synchronization messages" checked in 1.8.7, and however far back that option was available.

Have you used 1.8.10 to remux any blu ray MKV files that you have created with 1.8.10? It seems that these AV sync errors are discovered during the remuxing process, and are only present in files made with 1.8.10.

It's a distinct change that occurred somewhere between 1.8.7 and 1.8.10, and without my system having been changed, I don't know how to further troubleshoot this.

I'm suffering the same issue, but I've only recently started using 1.8.10. I came across this issue in re-saving default MKVs to WDTV profile MKVs using 1.8.10. I have to go through my 200 movies and find which ones have forced subtitles to make them compatible with my WD TV Live SMP, so I would love to know if I should wait or not.

FWIW, my titles save fine.

[ronblade]

Thank you, archangel3740, for being the first to confirm this behavior on your own system. I was beginning to wonder if I was alone in this. Something tells me that most users do not regularly remux their MakeMKV rips, because this is a really easy issue to spot when you do remux (with "show AV sync errors" turned on). It sounds like you were able to avoid a failure message, at least, when you included subtitles, so that is interesting. Due to the introduction of timesync errors in 1.8.10, though, I am sticking with 1.8.7 until this is resolved, and I recommend that you do, too.

I forgot this thread, well actually I thought it was about subtitles, since they were mentioned. I tried remuxing a file with MakeMKV to see if it fixed the MediaInfo variable frame-rate problem:

I thought the error be caused through processing a file modified with MKVPropEdit, so I re-ripped the episode and retried on the clean version and:

So I retried with a file remuxed with MKVMerge and:

The error may have nothing to do with this thread, but the 1ms time code message there may be. Or maybe not, since it's still there after being remuxed with MKVMerge. I thought the 1ms difference in the timecode existed because two audio streams shared the same timecode with the video, but if MakeMKV is reporting it as an AVSync issue I may have been wrong. I should stop posting now.
