automatically translate subtitles to a different language using LLMs

Auto Subtitle

Automatically translate subtitles to a specified language using GPT4.

Setup

sudo apt install mkvtoolnix
conda create -n subtitle python=3.12
conda activate subtitle
pip install -r requirements.txt

Usage

1. Start the program

   python auto_subtitle.py

2. follow the dialogs/prompts for:
   1. selecting a language
   2. selecting a video file
   3. selecting one or more subtitle files

Then the program should start the translation. When done translating, the subtitles will be merged into a copy of the video file saved at output/<video_name>.mkv.

Notes

• llm_log.txt contains the current in progress translation
• if llm_log.txt has partial content that matches the current translation (checked by comparing timestamps), then the program will pick up from where it left off
• completed translations are cached in the sqlite database file translations.db
