Synced subtitles still out-sync #48
Comments
Thanks for filing an issue. It's likely that your video contains splits / breaks in the middle -- unfortunately, this project is geared toward the common case when there's extra stuff present / missing from the beginning or end of the video. I want to extend the algorithm to handle these cases (I believe it is possible), but I'm afraid I don't have the cycles at the moment. See #10 for more details. |
@BramFr since you posted, there have been a number of improvements to subsync -- I know this issue is super old, but I'd love to hear whether it's working for your case after the recent improvements, if/when you have time. The latest version can be grabbed via:
If the sync still doesn't work, I would love to try to investigate further. It's now possible to build a tarball containing most of the data I need to investigate (without violating copyright), as follows:
The resulting test archive will be named |
Thanks for reopen this case.. After few try

@BramFr really appreciate your taking the time to take another look! Bummer about the test archive -- not sure exactly why that's happening. Possibly a problem with |
@BramFr I think I figured out the issue; creating the test archive should work now if you install from the
Please let me know if you have a chance to try to make the test case and whether it works -- would love to take a closer look if so. |

@BramFr I think I see what is happening here. Those subtitles look like they're the 1st choice from opensubtitles.org, but they seem to be mislabeled -- perhaps they are for a different episode of that TV show. I'd love to know if these ones work, if you have a chance to try them instead. (You'll be able to see that the text content differs significantly from the ones you attached.) manifest.s02.e09.airplane.bottles.(2020).eng.1cd.(8121898).zip |
sorry indeed wrong test i`ll find another one. Every subtitle came from bazarr (automatic) |
Gotcha. I need to see whether I can convince SubZero / Bazarr folks to use subsync as a tool for picking out already synced subtitles out of a batch of candidates; could potentially help filter these kinds of cases where the metadata is bad. And please @BramFr no need to apologize -- it's thanks to these kinds of test cases that I can continue making improvements, so I really appreciate the time you've already spent so far. |
i found one :)
The first 5min`s of this file "en.srt" is good. After 5min i get a intro with a black screen. After that subtile is out of sync. This file "en2.srt" already out-of-sync from the beginning. Man.with.a.Plan.S03E13.iNTERNAL.720p.WEB.x264-BAMBOOZLE.mkv.2020-03-17-06:52:55.tar.gz |
Forget about it, this srt is toast |
@BramFr unfortunately it looks like I need the exact video (and not just the speech trace) to debug, and I'm afraid I'm having trouble locating it. One workaround would be if the mkv has embedded subs -- that would serve as a good proxy. If the following command succeeds, I can debug by looking at the resulting extracted subs:
|
Stream map '0:s:1' matches no streams. i`ll send you a mail trough gmail with the episode. |
I've got another exemple of out-sync. Subsync detect -0.8 offset instead of -3.840. |
In my case, Bazarr downloads a subtitle that is actually in sync but then ffsubsync decides to unsync it by a tiny bit. Trying to figure out why. I'd like Bazarr to sync all subtitles regardless of score so I'm trying to figure out why it doesn't just leave this one alone.

@smacke do you have a update? Do you need any more information from me? |
Command:
subsync walking_dead_10x03.mkv -i walking_dead_10x03.srt -o walking_dead_10x03.nl.srt
Unsynced sub:
Synced Subs:
It seems the original subs are complete wrong. Looks like a different episode. But after the sync its looks alot better. But still few sec out-sync
When i`ll try another file: man with a plan s03e9
Unsynced:
Synced:
This one is complete out-sync. The first one must start around: 00:00:02,200 --> 00:00:04,100
