Diet-Video

This is a fork of the original video-diet that is no longer being updated.

This project aims to reduce the spaces of your videos and audios encoding it on hevc.

Why video-diet?

The answer is easy. I have a lot old-movies/videos and music/audios taking a lot of space in the hard-drive. So I'm always short on disk space, the by accident discover de hevc codec. when i need to shrink a video of 3GB to upload it to Telegram, the convertion take my 3GB movie and returned a 300 MB with the same quality 😱. So I decided that I would convert all my video and audio files , but they are a lot, so I build this tool for it.

Installation

$ uv tool install .

This installs the diet-video command. To run it from a checkout without installing it globally, use uv run diet-video.

FFMPEG

For Linux

In any linux machine you can get it from your favorite package manager.

For arch:

sudo pacman -S ffmpeg

Ignoring files on the folder

This option ignores all the .mp4 files on ~/Videos

diet-video folder ~/Videos --ignore-path ~/Videos/subfolder

This option ignores all the files on ~/Videos/subfolder

AV1 Support

To use AV1 instead of hevc add --codec av1 to the commnads above and that will use libaom-av1 instad of libx265 to encode the files

Note

The video conversion can take some time. Depending on the original video properties; the conversion time can be longer than the video.

For developers
