From the article:
FFmpeg is a tool almost every Linux user has benefited from, even if they have never typed its name in a terminal. It powers countless media workflows, handling video, audio, image, subtitle, and metadata processing with great flexibility.
The problem is that using it directly usually means dealing with long commands, codec names, bitrate settings, filters, containers, and much trial and error. Frame tries to make that part less painful.
It is an open-source desktop application providing a graphical interface for FFmpeg. Instead of replacing FFmpeg, it wraps it in a native app and offers users a cleaner way to configure common media conversion tasks. The project describes itself as a native media conversion utility built in Rust, using FFmpeg and FFprobe underneath for media handling.



Not a slight against the app whatsoever, but why yet another ffmpeg GUI? Handbrake perfected that years ago
the last sentence in the submission text might explain the ‘why’, at least from the project developer’s pov:
EDIT: i took the time to look and its not realky a gui for ffmpeg. it uses the same libraries but doesnt have the exact functionality as the ffmpeg program.
i feel very silly. i always thought handbrake was an alternative. i never took the time to find out more but never knew it was a frontend for ffmpeg.
