Audio - Video out of sync during

[hcmrah]

Having sync issues with the AV after processing a blu-ray disk. Have done around 25 blu-rays (newer movies I might add) and on all of them the the audio or video is out of sync during playback. Any suggestions?

AV sync issues during the rip (MakeMKV messages), or actually getting out of sync during playback?

I have noticed that a lot of players (Kodi on Android, for example) cannot keep audio in an MKV file synchronized for long periods. It isn't too bad on short videos (20-25 minute TV show episodes), but the longer it goes, the further out of sync things get. Same video in other players has no problems.

And it isn't just the output of MakeMKV - everything I rip goes through handbrake, and is output as both MKV and MP4 files (different targets). The raw MKV file and the processed MKV file will have sync problems, while the MP4 plays fine in Kodi.

Check the MKV file with other players, to see if the same issue exists. VLC is my primary "on computer" player, and it helps find a lot of compatibility issues.

It is out of sync during playback. I use VLC and PowerDVD 14 on my desktop for play back. I stream it to my New Samsung SUHD TV using Mezzmo Beta to Roku. Playback on all devices, has the same result, the video and audio are out of sync.

Does it get worse as playback continues? That is what I'm experiencing, but it does NOT happen in VLC on the PC... That seems to stay in sync.

It seems to stay the same through out the entirety of the movie(s). Does not matter which playback device...TV, VLC or Power DVD 14, the results are the same, out of sync.

During the rip, did MakeMKV log any AV Sync messages? You should make sure they're enabled in your preferences; Preferences->General, "Show AV synchronization messages" should be checked.

Did not have that checked off in preferences, will try another blu-ray, rip it and see what I come up with.

Tried another blu-ray, same results, checked the log and it did not generate one, none for that matter. Checked all the settings, will try ripping another see what happens.

Debug logging has to be turned on in the preferences, or the log is just what you see in the log window. With debugging on, more detail is saved, and it is put into a specific file on your system. The FAQ in my signature explains how to turn it on and where the file will be saved.
