==== SUMMARY I'll try to keep it short (and skip also the natural appreciation part for all your work, which I do but...): I find the UI of the "Time Remapping" alias Speed Ramp ***EXTREMLY*** not only un-intuitive (bad UX) but even limiting in (possible) functionality . ==== STEPS TO REPRODUCE Try to figure out "Time Remap" without a tutorial -- without being the dev/creator of the UI/UX (Off-Topic but doesn't enhance the situation: while at the same time it's constantly crashing on you, see #437113). Really, I mean it. Put your uninformed uncle/cousin/whoever in front of this, tell him: here is this new feature in kdenlive, please make me this: https://youtu.be/W1SbGOl9YEc?t=308) ==== OBSERVED RESULT A) Under specific circumstances extends the clip (probably it's a feature but regarding UX completely unexpected and unintended) B) With a lot of "ramps" granularity/accuracy gets lost due to weird scaling of the "Time-Ramp"-UI B2) Under certain circumstances cannot click handles in the """graph""" due to overlapping/aids of the UI C) Not even sure if this is intended but you can even reverse time. -- Not anytime soon I would have realised that! (Though the feature at all integrated here really sounds great.) [2] ==== EXPECTED RESULT A graph where I could even have control over the kind/speed/slope of the ramp/function (not only "please magically cramp 2 minutes into 1 minute for me") ==== ADDITIONAL INFORMATION Maybe I'm just ignored but can the master mind behind the UI please explain the benefits of the current "fancy" UI over a regular graph/function which "everybody", I would claim, with a descent educational background would expect and could grasp in an instant. AGAIN: I really appreciate your work and *even* a new/different approach over the "classic" one but only if it brings benefits. The documentation for this feature is a one-liner which literally just and only states: "The new Time Remap feature allows to keyframe the speed of a clip."[1] (Since then a whole *major* release has passed.) ____ [1] https://docs.kdenlive.org/de/effects_and_compositions/effects.html#time-remapping-speed-ramps [2] https://youtu.be/weY57YFPD-g?t=222
