Subtitles Editor

This editor allows you to make edits to SubRip Text (SRT) files with subtitles - shift the timestamps, do a linear correction, or translate them to another language.

Features

Colorizer for SubRip Text (SRT) files.
Shift all timestamps by a specific time value.
Renumber frame sequence with specified start index.
Reorder frames based on their sequence number.
Linear correction by mapping two existing time stamps to new values.
Translate subtitles to different languages.
Only subtitles in selection are affected. If there is no selection, all subtitles are affected.

Usage

Use command Subtitles: Shift and enter offset time to shift subtitles. The format is "HH:mm:ss,zzz". You can use negative time if subtitles are too late.

With Subtitles: Renumber, you can renumber the frames using the sequence with specified start index. After selecting this options, enter the start of the sequence (usually 1) and it will be renumbered accordingly.

The command Subtitles: Linear Correction prompts you for two timestamp mappings. The input is in form "original timestamp -> new timestamp". Pick one point from the beginning of the movie and second one from the end of the movie to get the best approximation.

Use command Subtitles: Translate to translate subtitles to another language using Google translation service.

With Subtitles: Reorder, you can reorder the frames based on their sequence number. This can be useful if you want to work with translated and original subtitles at the same time. You can first translate the subtitles (which will replace the original ones) and append the original subtitles at the end. Then, you can reorder them so you will have translated and original frames near each other.

Updating Supported Languages

The languages that can be used for translation are published by Google in Google documentation. The extension uses languages defined in src/languages.json file.

To convert the published table to JSON:

copy the table from Google documentation (https://cloud.google.com/translate/docs/languages)
replace ^(.*?)\t(.*?)(?: $.+$)?$ with \t"$2": "$1",
remove the last comma
wrap the result in curly braces
save it as src/languages.json
