I've been trying to loop a robotic arm extending out and then retracting back in. It's a 2 second animation. However, on frame 01:24 there's a stutter that shows blurred movements for a split second of the arm that occurs neither in the frame before or after it - it's like it's jumping back even earlier in the timeline for a single frame and then loops the rest normally. The flicker is becoming quite distracting.
I'm relatively new to After Effects and I've been fiddling with this for days, scanning the forums and looking at tutorials and all sorts of things, but I just can't seem to fix it. I'm sure it's probably a simple solution and I'm just not understanding something basic about loops but I'm quickly running out of time and it still isn't working. Does anyone have any ideas?
