Who else is excited for GPU accelerated compositing nodes!? Me too, except! They still only work in a limited implementation in blender. In this video I show you a workaround to be able to do light footage compositing using the real-time viewport compositor.

In the tutorial I forgot to subdivide the plane a bunch. You should probably do that for best practices.

Get Blender 3.5 Alpha with the realtime compositor here: https://builder.blender.org/download/daily/
