I have a scene with a fluid simulation and I want to know if the result is better with or without the Vector Blur node.
Is there a way to render a video where Blender first renders the image and exports it to a file and then adds the compositing nodes and exports the image to a different file?
This way you will get two video's at the end, one with compositing and one without.
This would save a lot of render time because you only have to render it once.
