I have a RPi 3 B+, UTV007, Arduino Nano (clone), and 266 LED setup. Things are working fine, but I notice a very slight delay. Just wondering what the likely cause is. It's probably a frame or 2. There is no smoothing in the config. I would guess that there is a frame of delay (if not more) in the grabber. However, I also thought there might be a smidge of delay from the Pi to the Nano. Could that be the case? could I get a frame of speed back if I went with a logic converter rather than using the Nano? There must be a way to sync it all up. I wonder if I can delay the picture on the TV and then delay the audio on the new receiver that the Black Friday elves will bring me. Any thoughts? FYI: I am an After Effects animator, so I create video and deal with timing (in a creative visual sense) all day. This delay might ruin the Ambient light for me. Thanks!
