alass VS jimaku-player

Try alass or ffsubsync.

I use https://github.com/kaegi/alass to retime subtitles automatically. I've never worked with a file that has the issue you're describing but it does claim to fix frame rate issues.

You need an english softsubbed source, JP subs (kitsuneko), sync them with https://github.com/kaegi/alass, then set up POTPlayer for multiple subtitle files.

Check this project here: https://github.com/kaegi/alass

If you want subtitles for anime, kitsunekko usually has subtitles (and Netflix also usually has native subtitles and you can download them using subadub). The downside with using subtitles from a different source is you need to re-time them but tools like alass make this basically painless in most cases. For movies, Netflix or the DVD version of movies usually have subtitles.

I've used https://github.com/kaegi/alass and sometimes it works, sometimes it doesn't. It's not an easy problem to address automatically...

Video players wouldn't want that in their codebase, maybe if it was available as a C library.

With tools like alass[1] (using it to synchronise against the original language subtitles) it is about as close to solved you can get.

All of the attempts I've seen of using audio information to synchronise subtitles have been awful (some languages subtitle everything, even screams and incoherent shouts -- such as Japanese -- while others only subtitle dialogue and often rework dialogue for the purposes of making the subtitles short enough to be readable easily).

I used jimaku player for a couple of months…where if you find the jsubs file it will plug it in crunchyroll…the creator is also very active on their discord and can answer any questions you may have (as long as it’s not “where do I get jsubs from…lol anything else goes)

Dnt think that exists..but if you use crunchyroll you could use an extensions called jimaku player which allows you to see jsubs next to english subs...but ofc you have to hunt for the jsubs yourself tho...

With crunchyroll you could use jimaku player

Never tried it myself but checkout this extension for crunchyroll. Might be what you are looking for.

The episode number and the exact time for the scene would make it easier for people to help you. Alternatively, you can find Japanese subtitles online, and sync it up with the video file. There's a plugin for Crunchyroll's player you can get that does it. See here.

You can get JP subtitles onto Crunchyroll using this tool :)

Here's the github page for anyone interested: https://github.com/sheodox/jimaku-player

Use https://github.com/sheodox/jimaku-player to use your own subs on crunchyroll otherwise piracy is always an option.

If you have subtitle files (.ass/.srt files) and use VRV/Crunchyroll you can use a tampermonkey script I made a while ago to use your own subtitles on those sites: Jimaku Player
