Just a workflow to interpolate videos (make them have high FPS to be smooth)

Nothing overcomplicated only 3 nodes. If your input video is 24 fps and the RIFE multiplier is set to 2 set video combine frame_rate to 48. I have done 96 fps on the frame_rate when RIFE was set to 4 and it didn't cause any weirdness just got a smooth 96 fps video.

Recipe is: Input video's FPS X RIFE multiplier = frame_rate
