About This Project

This project

  • uses openai/Whisper from OpenAI to generate video subtitles automatically.

  • adapted some codes from m1guelpf/auto-subtitle.

  • uses the base model from openai/Whisper. Which is multi-lingual and fairly fast. If you want to use a smaller model, you can change the model in main.py to tiny. However, the accuracy will be lower.

  • has been tested on a youtube video of 8 min duration. It took around 2 min to generate the subtitles on my mac (CPU, Quad-Core Intel Core i5).

Potential Application

  • Generate time-stamped subtitles for your video. Would be helpful in video editing.
  • Add subtitles to lesson recordings to learn 3x faster by reading subtitles instead of listening. You might also navigate lectures via keywords.
  • and more...

Installation

Dependency:

  1. ffmpeg: used to extract audio from video
  2. whisper: used to generate text from audio 
    pip install whisper, ffmpeg
# or
pip3 install whisper, ffmpeg

It might take a while to install whisper. Please be patient.

Usage

It's fairly simple, just copy and paste the following commands in your terminal.

  1. Download the project

    git clone https://github.com/madeyexz/whisper_subtitle.git

  2. Run main.py, where video_path is the path to your video file and -LanguageCode is where you choose the language of the subtitles.

    • Currently only -en and -zh is available for English and Chinese subtitles respectively. However if you don't specify the language, it will choose language automatically.
    • If its your first project with whisper (especially with base model), it will take a while to download the model. Please be patient.
    python3 main.py -LanguageCode video_path

    e.g.

    python3 main.py -en video.mp4

  3. Collect the result. The result will be saved in the same directory as the video file and will be named as the video file name with .srt extension.

  4. Play the video with subtitles. You can use VLC or any other video player. Just put the .srt subtitle file in the same directory with the original video and play the video via the video player. Also, check if the subtitle file has the same name with the video.
