Hi there. Works pretty well for me. Can confirm the CPU usage, but not a real issue imo.
However I'm struggling with one thing: Since it's a video filter, I can only apply it directly to the camera source. This means once I've applied it, it's applied to all the copies of the camera source too. Since I would like to use the camera in another scene, but without the background removal, I'm running into an issue here. Applying the filter to a group or a scene doesn't work, since that only allows for effect filters. Do you have any suggestion on how to bypass this? Thank you very much!
