What is Videomass?

Videomass is a GUI designed for FFmpeg enthusiasts, who need to manage custom profiles to automate conversion/transcoding processes even with multiple files in series (batch processing).

It is based on an advanced use of presets and profiles in order to use most of the FFmpeg commands without limits of formats and codecs.

It features graphical tools for viewing, analyzing and processing multimedia streams and downloading videos via youtube-dl and/or yt-dlp.

Videomass is Free (libre) Software, created and maintained by Gianluca Pernigotto (jeanslack); it was written in Python3 using the wxPython4 toolkit; it is cross-platform and works on Linux, MacOs, Windows and FreeBSD.

Videomass Logo and related artworks are created by Gianluca Pernigotto (jeanslack) and by KDE/Breeze Icons.

It includes libavcodec - the leading audio/video codec library.” FFmpeg is a Trademark of Fabrice Bellard, originator of the FFmpeg project. FFmpeg is free software and is licensed under the LGPL or GPL.

What is youtube-dl?

youtube_dl is a command-line program to download videos from and a few more sites (actually, the list is long). It requires the Python interpreter, version 2.6, 2.7, or 3.2+, and it is not platform specific. It should work on your Unix box, on Windows or on macOS. It is released to the public domain, which means you can modify it, redistribute it or use it however you like.

What is yt-dlp?

yt-dlp is a youtube-dl fork based on the now inactive youtube-dlc. The main focus of this project is adding new features and patches while also keeping up to date with the original project. The project development page can be found here.
