Bad Scratchy sound

[kirkdickinson]

I am new to MakeMKV. Started on a project to put all my DVD's into a Plex server. I am only about 20 in so far and have been spot checking the files. One project in particular is a mess.

The from about the 5th file generated to the end, the sound is very scratchy. One of the files, "Title04.mkv" appears to be a very short file when I first open it, but is 3.5 Gig and seems to have most of the dvd on it, but the index seems corrupt or something. When I first open it in VLC media player, the index reports 8:50, it plays about 10 seconds of the song while the scrubber quickly runs to 58:56. If I manually move the scrubber, I think all the video is there and the sound is good.

Weird.

This is a dvd of musical performances by a solo artist.

17 files from title00.mkv to title16.mkv

title00.mkv to title.01.mkv are inro things.
title02.mkv is a song
title03.mkv is a making of this recording type segment with an interview with the artist.
title04.mkv is the balance of the songs (about 9)
title05.mkv - title16.mkv seems to contain the same content as title04.mkv, but it is broken up into separate files and those files have really bad sound.

Could you enable debug logging (see link in my signature) and re-rip the disk, and post the log so we can see what MakeMKV is doing?

If you have not enabled any audio conversions (requires "Expert mode" to be enabled and using a non-default profile), the audio should be exactly as it was on the DVD.

Sure thing, I will do that right away.

Thanks,

File is HUGE. Never seen a 4MB log file.

I attached it instead of posting it.

I noticed that the times are different than my system time. Is it going by GMT?

Can't post the log because it is too big. Can't attach the log and when I try to link to it, it says that post has to be approved by admin.

Looking at the log, I see this:

Code: Select all

AV sync in 1 at 0:00:03.893 (1.666ms) : audio gap was filled with silence
AV sync in 1 at 0:00:03.935 (1.666ms) : audio gap was filled with silence
AV sync in 1 at 0:00:03.976 (1.666ms) : audio gap was filled with silence
AV sync in 1 at 0:00:04.008 (1.666ms) : audio gap was filled with silence
AV sync in 1 at 0:00:04.050 (1.666ms) : audio gap was filled with silence
AV sync in 1 at 0:00:04.081 (1.666ms) : audio gap was filled with silence

MakeMKV is trying to keep the audio track synchronized with the video, but the time stamps seem to be really screwed up. As such, the inserted silence would sound like scratchy audio.

We will have to wait for Mike to look at this, to tell if there is a way to disable the track synchronization.
