There was an ffmpeg drag-and-drop GUI that let you create ffmpeg commands visually instead of having to remember all the right arguments. Inputs, filters and outputs are all nodes in a graph, and then you connect them together. When done you would export it as an ffmpeg command to run.
As an occasional user this was a lot easier to use than having to remember all of the commands, and it did it all without hiding the complexity from the user.
Unfortunately it looks like they tried to monetize it but then later shut down. It doesn't look like they posted the source code anywhere.
