Adjust SRT Subtitle Offset in the UI

So, Plex is awesome in many ways. but when it comes to subtitles, functionality is lacking. I won’t turn this into a rant. but one simple additional feature would solve 99% of my problems with subtitles.

SRT Subtitle files are simple text files containing a sequence of subtitle phrases, each of which is preceded by two timestamps for when the subtitles phrase should be displayed and then removed. This timestamp is expressed as hours, minutes and seconds relative from the start of the matching AV file.

In my experience, many subtitle files for the same TV show / movie have different timestamps for the same subtitle phrases. This is particularly true of TV shows which are cut differently (normally to fit around advert and time slots) for more or less every network they are broadcast on.

There are a number of online tools to add/subtract an offset from an entire file, which is fine if the offset is constant, but in many cases it changes throughout the file as cuts are made to accommodate advert breaks.

SOLUTION / REQUEST: A simple option to change this offset in real-time within the UI.

This does currently exist for some types of subtitles, but when using SRT files no such option is available.

Just a simple +/- slider in SECONDS is needed. (NOT milliseconds as in the current implementation which is entirely unnecessary and totally impractical when the subs are 20 seconds adrift)

It actually exists specifically for SRT or other text-based subtitles

So, as I said the real time offset adjustment is not available when I use an .srt file alongside the AV file on my server.

So, if it’s supposed to be there is this actually a bug?

I already voted on issues like the ridiculously small 50ms increment change 4 years ago, and still nothing has changed…, another issue you suggest voting on is nearly 10 years old…

If basic stuff like this is not getting addressed within a ten year time frame, then I think it’s time to move on and get to grips with Jellyfin.

Feel free close this thread.

Is the video transcoding?

Subtitle offset is available only when the video is direct playing/streaming.

If the video is transcoding, subtitle offset is not available.

Hi, thanks for replying, and yes, it’s transcoding. So it’s not a bug, but another feature that prevents very basic functionality from working… and it doesn’t get more basic than “Can I use Plex to play my media files?” to which the answer is NO.

As I said, time to move on and find something that can…
