Issues with subtitle syncing - growntomcat - 2024-07-07
When putting particular movies with subtitles on jellyfin, there are moments where the subtitles will completely go off track to a different part of the movie. However when I view the file on my local computer using VLC, the subtitles sync just fine? If it matters, I use MKVToolNix to mix subtitles and video and I export it locally and then upload to my jellyfin.

What kind of subtitles are the and what client are you having issues on? Does this issue happen with all clients?
RE: Issues with subtitle syncing - growntomcat - 2024-07-08
They are SRT files, it's my firefox web client, yes it happens on all clients.

Are the subtitles external or embedded? Are you able to attach the SRT subs to a forum post so we can examine the contents?
RE: Issues with subtitle syncing - growntomcat - 2024-07-08
I believe they are external as I can toggle them on and off. I don't think I am allowed to attach SRT files so I have created a link to the download: https://files.catbox.moe/4g0vb3.srt
I don't think there's anything wrong with the SRT files as they work perfectly on VLC locally.
Also an update on the subtitle issue: It doesnt seem to be going off track any more, but when brushing through the film the subtitles will go off sync about 1-2s and generally when watching it they seem to go off.

I also noticed subtitle sync issues with subs mainly if I continue watching after a certain time. If I start a 25min show 10mins in I can expect the subs to be a second off and have to use the subtitle offset. Seen it with PGS and ASS subs. Also I feel the offset is backwards; if the subs are a second early, I'd expect to use an offset of "+1s" to offset them by +1s but that makes the subs even earlier. It's more like using the slider to tell JF the subs are "currently at -1s", rather than telling JF to offset the subs by +1s. Hope I explained that half-decently.

There are two warnings when I run this sub through a validator.
I placed the subs in a random movie and these warnings only caused the subs to stack or shift briefly. So I doubt they are the issue.
