Is there an effect to reduce the frame rate / posterize time (as after effects calls it) - with out changing the length of the clip / for live sources?
Perhaps I missed it, but I only find effects to blur btwn frames. The best work around (kinda) is to use a step sequencer to turn on/off a freeze frame effect. Which isn’t exactly great and has limited speed control options at best.
With video files I know you can just play them slower. Basically trying to replicate a video feedback set up I had with a hardware mixer and a camera - reducing the fps on the feedback input to keep it blinking out of control.
