Hi Dan,
Yes that’s what I’m looking for. I would like to flexibility of moving markers around to different frames for a stop-motion effect the last frame is frozen until the Time marker gets to the next marker. I would just use Time Remapping and Hold keyframes if I didnt want the option to change the frame and the timing easily. As I’m an expression novice, I’m a bit clueless. Obviously the expression I’m looking for would be much more involved.
