srtedit

A command-line tool for quickly editing subtitle (.srt) files.

Installation

pip install srtedit

Basic Usage

Offset subtitles in milliseconds

srtedit subtitles.srt --offset 1000 -o modified.srt

Will add exactly 1 second to all subtitle elements. Conversely:

srtedit subtitles.srt --offset -1000 -o modified.srt

Will subtract 1 second from all subtitle elements.

Offset individual subtitle element

Use the -s/--select option to select an individual element to offset. Example:

srtedit subtitles.srt -s 1 --offset 2000 -o modified.srt

Will add 2s to the first subtitle element only.

View contents of subtitle element

srtedit subtitles.srt -s 1 --view

Will display the start/end times and the content of the selected element. Omitting the -s option will display all subtitle elements in the file.

Note: The output from --view is not compatible with the .srt format. You should use the -o/--output option when writing any files.

Remove subtitle element

Use the -r/--remove option to remove a selected element.

srtedit subtitles.srt -s 1 --remove -o modified.srt

Edit subtitle element

srtedit subtitles.srt -s 1 --edit "New text" -o modified.srt

Count number of elements

srtedit subtitles.srt --count

Multiple options

You can use multiple options together like this:

srtedit subtitles.srt -s 1 --edit "New text" --offset 1000 --view -o modified.srt

Will set the text of the first element to "New text" then add 1 second to the start and end times and then display the new values to the terminal and then finally write it to modified.srt

Disclaimer

Note that srtedit will select all subtitle elements by default. Omitting the -s/--select option will result in the specified operation (--edit/--remove/--offset) being applied to all elements.

Without specifying an output path, you can use the --view flag in conjuction with any of the operations above to see your changes before writing.
