My intuitive interpretation has been that `jank` is related to frame dropping but with time perception being constant (like sampling being insufficient yet played at correct times) whereas `judder` also has a sort rubberbanding effect on time, where time is perceptutally compressed or dilated as playback is delayed or "catches up", with frame dropping happening upon e.g a deadline being missed. Here, with frames 2 and 4 being costly to render: normal: F1....F2....F3....F4....F5....F6 jank: F1....F2..........F4..........F6 judder: F1....F2........F3....F4......F6
