Time shift all subtitles in an SRT file by a given amount

srt-shift

A simple project to shift all subtitles in an SRT subtitle file by some timespan.

The impetus for this project is that I use ccextractor to convert the closed captions from TV shows that I've transferred from my TiVo using kmttg. However on some channels the subtitles end up showing later than they should, off by about a second or so. This is really annoying and easily correctable because the SRT subtitle file is quite simple.

The implementation in this repository is needlessly complex because I'm taking the opportunity to figure out how to write a nodejs utility to do it. I'm initially starting with a commandline utility but I came across electron so I may also explore using it to provide a GUI.

The best tool for the job is probably a simple awk script which I may eventually also create.

Development

Node version

See the package.json for minimum required node version (currently v6) as well as other dependency versions.

The source code is typescript which is compiled into the dist subdirectory.

The entry point is src/main.ts => dist/main.js.

Use npm or yarn to install the package dependencies then build the sources into the dist subdirectory.

• npm install or yarn install
• npm run build or yarn run build

Run the compiled code:

• node dist/main.js

awk version

To be implemented.
