I might be a little confused. Currently there are three main end-user
video-processing instances in Kdenlive:
(1) Clip Monitor & Timeline playback
(2) Preview rendering
(3) Final video rendering
Exactly which one(s) of these is Movit GPU library supposed to apply to?
Movit provides a set of filters (effects) that process the video frames on
the GPU instead of the CPU.
These filters are usually drop-in replacements of existing (CPU) filters,
which means that movit doesn't actually provide additional functionnality,
but rather computes the same result differently
