I’ve been playing with the idea of moving all my compositing work to the Blender compositor, but compared to other professional compositing software such as, Nuke, After Efftects, or even Combustion or Shake, it is slow, slow, slow. Like really slow. Unusably slow.
Just loading a clip and playing it back from a viewer in a UV/Image editor is painful. I’m pulling the images from a dedicated high speed RAID over thunderbolt with a xfer speed of >500 MB/s, or 1 gigabyte every 2 seconds. So, my hardware is not the problem. I do this kind of thing in other software as a daily, nay hourly, part of my regular work.
Here’s the setup:
Step 1) In the compositor, import a movie clip.
Step 2) connect it to a viewer node.
Step 3) Display the viewer in a UV image editor window.
Step 4) Ensure your “Timeline Playback Controls” have playback synced for “Image Editors” and scrub the timeline.
Step 5) Slowly shake your head at the playback speed.
What gives? Am I just not getting how to set this sort of thing up in Blender? Prefetching frames and playing them back in the Movie Clip Editor seems okay. This is the kind of performance I would expect in the compositor, but far from it.
