Subtitle

Open-source subtitle generation for seamless content translation.

Key Features:

  • Open-source: Freely available for use, modification, and distribution.
  • Self-hosted: Run the tool on your own servers for enhanced control and privacy.
  • AI-powered: Leverage advanced machine learning for accurate and natural-sounding subtitles.
  • Multilingual support: Generate subtitles for videos in a wide range of languages.
  • Easy integration: Seamlessly integrates into your existing workflow.

I made this project for fun, but I think it could also be useful for other people.

Installation

FFmpeg

First, you need to install FFmpeg. Here's how you can do it:

# On Linux
sudo apt install ffmpeg

Run

You can run the script from the command line using the following command:

python subtitle.py <filepath | video_url> [--model <modelname>]

Replace <filepath | video_url> with the path to your video file. The --model argument is optional. If not provided, it will use 'base' as the default model.

For example:

python subtitle.py /path/to/your/video.mp4 --model base

This will run the script on the video at /path/to/your/video.mp4 using the base model. Please replace /path/to/your/video.mp4 with the actual path to your video file.

Models

Here are the models you can use: Note: Use the .en model only when the video is in English.

  • tiny.en
  • tiny
  • tiny-q5_1
  • tiny.en-q5_1
  • base.en
  • base
  • base-q5_1
  • base.en-q5_1
  • small.en
  • small.en-tdrz
  • small
  • small-q5_1
  • small.en-q5_1
  • medium
  • medium.en
  • medium-q5_0
  • medium.en-q5_0
  • large-v1
  • large-v2
  • large
  • large-q5_0

Advance

You can modify the behaviour by using these parameters whisper binary as follows:

./whisper [options] file0.wav file1.wav ...
