I'm continually blown away by your work! I have a question, though: Is there a way to set up Blender to render through this directly rather than exporting a video and adding it to the image input?
Hmm, I'd usually just plug in the video I want rendered into the image input and render out the result as either a png sequence or a video file, it's material shader based so the input video has to go "through" that process somehow :)
