Why is the viewer node in the compositor mode so slow in blender? It seems as if it is only capable of refreshing single frames, but not the whole video.
Is there a way speed up the process?
edit1, explanation:
I'm working on a very short chromakey clip. In order to preview the results I either have to step very quickly through the frame-timeline, or render the final result to a file. Latter option is also very slow, therefore I would rather prefer a quicker preview option.
