Subtitles Generator

Simple module written in Javascript with ECMAScript module format.

Exports one function that uses FFmpeg and OpenAI Whisper API to generate an English subtitle file for a video in a foreign language.

FFmpeg must be installed.

Input:

• The path of the video file
• A valid OpenAI API key
• A comma-separated list of words helpful for correcting specific words or acronyms that the model may misrecognize. The string will be used as-is in the OpenAI Whisper prompt. Should be in English.

Output:

• A subtitle file in the desired language, created in the same folder as the video folder.
