srt-timer simply converts subtitles from one timing to another one.

You downloaded Fear the Walking Dead, episode 03x06, version 720p.WEB-DL-RARBG and you want to have an Italian subtitles. However Italian subtitles are just for the version REPACK.SVA...

Now you can simply use srt-timer for convert the subtitles to the wanted version. First, you have to download English subtitles in both REPACK.SVA and 720p.WEB-DL-RARBG and then you can create repack2webdl.sdiff file with conversion information:

$ srt_timer make_sdiff --strip-original 11 \
> "Fear the Walking Dead - 03x06 - Red Dirt.REPACK.SVA.English.C.orig.Addic7ed.com.srt" \
> "Fear the Walking Dead - 03x06 - Red Dirt.WEB-DL RARBG.English.C.orig.Addic7ed.com.srt" \
> --output repack2webdl.sdiff

strip-original argument removes the preview subtitles that shouldn't be in the final version.

Now you convert your Italian subtitles to 720p.WEB-DL-RARBG version with the created sdiff file:

$ srt_timer convert --sdiff repack2webdl.sdiff \
> "Fear the Walking Dead - 03x06 - Red Dirt.REPACK.SVA.Italian.C.orig.Addic7ed.com.srt" \
> --output italian_webdl.srt

And you're done.

The package is on Pypi, so you can install it simply with pip install srt-timer

For help just type srt_timer --help or srt_timer [command] --help

For all commands, the result is printed to the standard output by default. If you define the output argument, then it's printed to a specified file.

Convert srt file from one timing to another one.

You can use it with a sdiff file like in the usage example or you can convert subtitles directly by providing original-timing and new-timing arguments instead of sdiff argument. In the second case you can also provide the strip-original argument to strip surplus subtitles on the beginning of a file.

Create a sdiff file.

It has two required arguments: srt file with original timing and srt file with wanted timing. Optional arguments are strip-original and output.

The strip-original argument should be number of the last subtitle in the "You've seen previously..." section if it isn't desired in a new subtitle version. If defined, it will trim all subtitles starting before or at the time of the provided subtitle.

Create a sdiff file for the backwards conversion.

This command expects just one argument input - a sdiff file. It will change its information, so it's possible to execute the opposite conversion.

$ srt_timer reverse_sdiff repack2webdl.sdiff -o webdl2repack.sdiff
