springTiming()

A timing function for <TransitionSeries> based on spring().

SlideTransition.tsx
tsx
import {springTiming, TransitionSeries} from '@remotion/transitions';
import {slide} from '@remotion/transitions/slide';
 
const BasicTransition = () => {
  return (
    <TransitionSeries>
      <TransitionSeries.Sequence durationInFrames={40}>
        <Letter color="#0b84f3">A</Letter>
      </TransitionSeries.Sequence>
      <TransitionSeries.Transition
        presentation={slide()}
        timing={springTiming({
          config: {
            damping: 200,
          },
          durationInFrames: 30,
          durationRestThreshold: 0.001,
        })}
      />
      <TransitionSeries.Sequence durationInFrames={60}>
        <Letter color="pink">B</Letter>
      </TransitionSeries.Sequence>
    </TransitionSeries>
  );
};

API

An object with the following properties:

config?

A spring config, see spring().

durationInFrames?

Stretch the timing curve of the animation to a fixed duration.

durationRestThreshold?

At which point the animation is considered to be finished. Default: 0.005.

reverse?v4.0.144

Reverse the timing curve.

Recommendation: Set a low duration rest threshold

The default durationRestThreshold is 0.005 (same as spring()). This means that if the animations has progressed 99.5%, it is considered to be finished.
For a transition, this can lead to a slightly noticeable cutoff of the animation:

To avoid this, set a low durationRestThreshold, we recommend 0.001.

Consider that this will also increase the duration of the animation. If you set a fixed durationInFrames, the animation will feel faster because it for longer it is not considered to be finished.
