timeremapping
Time remapping is a technique in video and animation that alters the playback timing of a sequence by mapping input time to output time. It enables non-linear pacing, allowing footage to be sped up, slowed down, frozen, or reversed. A time remapping system assigns a time value to each frame or sample along the timeline, with keyframes marking desired time values and interpolation generating the in-between frames.
In practice, time remapping provides a range of effects, including speed ramps where speed changes gradually
Quality considerations include potential artifacts from insufficient frame sampling, such as stutter or blur. To improve
