The video interface is intended for displaying the interface on an hdmi monitor, and it does that really well.
The video output is clean and records well. I wish that more/every manufacturer would provide that functionallity.
The video-art mode is low-res, unsupported, unfinished, and mostly undocumented (as of firmware v2.0).
I think Xor just thought it was an interesting hack, and kept what he had in the release, but it's sort of borked.
I got it to do some "things" but I was dissapointed I couldn't do basic drawing with it (draw a pixel/line at XY with this color).
It has a some potential, but also is limited by what the embedded video controller hardware is capable of.
Graphics mode also eats up one of the precious few tracks when using it for visuals.
Video synthesis it ain't, so don't buy it for that, but some audiences might enjoy seeing the tracker interface.
