animation driven by useCurrentFrame and interpolate

A programmatic animation pattern in Remotion that maps the current video frame to style values using a declarative interpolation function.

In Remotion, a React framework for programmatic video creation, developers drive smooth visual transitions by combining the useCurrentFrame hook with the interpolate helper function. The hook retrieves the exact timeline position of the rendering engine, while the interpolation function maps this frame number from an input range (such as frames 0 to 20) to an output range (such as opacity values 0 to 1). This mathematical mapping eliminates the need for complex CSS keyframes, allowing developers to precisely orchestrate multi-stage fades, translations, and spring-based animations directly within React component styles.
