webvtt-to-json

Convert WebVTT to JSON, optionally removing duplicate lines

Installation

Install this tool using pip:

pip install webvtt-to-json

Usage

To output JSON for a WebVTT file:

webvtt-to-json subtitles.vtt

This will output to standard output. Use -o filename to send it to a specified file.

Subtitles can often include duplicate lines. Add -d or --dedupe to attempt to remove those duplicates from the output:

webvtt-to-json --dedupe subtitles.vtt

Use -s or --single to output single "line" keys instead of a "lines" array.

You can also use:

python -m webvtt_to_json ...
