So I have a very peculiar problem with #blender.

I have an over 50k frames long project with render times 1-3 seconds per frame. It is hard to optimize render time further but there is a hope. Project has many places with significant amount of consecutive identical final frames. It would be nice to be able to tell blender, that it has to render the frame once, then reuse it for f.e. next consecutive 200 frames. With my current encoder settings this would mean 20-30fps render speeds on such long consecutive still frames; a few seconds of rendering except a few minutes.

Is something like this possible?
