LeGen

LeGen is a Python script that normalizes video files using vidqa, transcribes subtitles from audio with Whisper, translates generated subtitles using Google Translator, saves subtitles in .srt files, inserts subtitles into .mp4 container and burns subtitles directly onto videos using FFmpeg.

This is very useful for making it available in another language, or even just subtitling any video that belongs to you or that you have the proper authorization to do so, be it a film, lecture, course, presentation, interview, etc.

Usage:

To use LeGen, run the following command:

python legen.py -i [input_dir] --model [model_name] --dev [device] --lang [language_code] --crf [crf_value] --maxrate [maxrate_value] --srt_out_dir [output_dir_for_srt_files] --burned_out_dir [output_dir_for_burned_files] --overwrite --disable_srt --disable_burn --only_video

The available arguments are:

• -i/--input_dir: Path to the folder containing the original videos (required).
• --model: Path or name of the Whisper transcription model to use (default: "medium").
• --dev: Device to use for the Whisper transcription (options: "cpu", "cuda", "auto"; default: "auto").
• --lang: Language code to use for the subtitles translation (default: "pt").
• --crf: CRF value to use for the output video (default: 20).
• --maxrate: Maxrate value to use for the output video (default: "2M").
• --srt_out_dir: The output folder path for the video files with subtitles embedded in the MP4 container and SRT files. (default: legen_srt_[input_dir]).
• --burned_out_dir: The output folder path for the video files with burned subtitles and embedded in the MP4 container. (default: legen_burned_[lang]_[input_dir]).
• --overwrite: Overwrite existing files in output directories.
• --disable_srt: Disable .srt file generation and do not insert subtitles in the MP4 container of $srt_out_dir.
• --disable_burn: Disable subtitle burn in $burned_out_dir.
• --only_video: Do not copy other files present in the input directory to the output directories. Only generate the subtitles and videos.
• --only_srt_subtitles: Only generates the subtitles. Do not encode the videos or copy other files.
