vttdiff

This is a small utility for "diffing" two (or more) WebVTT files and generating an HTML file like this. It was designed for comparing a "ground truth" WebVTT file with WebVTT files that might have been created with different software or services.

usage: vttdiff [-h] [--output OUTPUT] [--include-times] [--width WIDTH] vtt [vtt ...]

positional arguments:
  vtt              The path to two (or more) WebVTT files

options:
  -h, --help       show this help message and exit
  --output OUTPUT  Write output to this file path
  --compare-times  Include cue times in the diff
  --width WIDTH    The default width (in characters) of each transcript in the diff

So you could run it like:

% vttdiff --output diff.html first.vtt second.vtt

Install

You should be able to pip install vttdiff:

$ pip3 install vttdiff

or just run it directly:

$ pipx run vttdiff

Develop

vttdiff uses Python's difflib and is held together by duct tape and baling wire. If you have ideas for improving it please send a PR!
