An edit that survives export
Unlike preview speed controls, this tool changes the file frame rate. Frame positions and start offsets remain intact. A two-second animation at 2 times speed becomes one second. Time-remap values are adjusted with the new time base.
Reverse the exported animation
Reverse wraps the original artwork in a time-remapped composition. The first output frame matches the last source frame, and the last matches the first. You can combine it with a speed change. Browser playback is checked with lottie-web; verify time-remapping support in your target native player.
Expressions need preparation
Expression-driven motion can depend on elapsed time. Bake expressions into keyframes before changing speed. Stale editor metadata is removed after retiming so it cannot restore old timing when imported.
