Trimming

Use `` with a negative `from` value to trim the start of an animation. ## Trim the Beginning A negative `from` value shifts time backwards, making the animation start partway through: ```tsx import { Sequence, useVideoConfig } from "remotion"; const fps = useVideoConfig(); ``` The animation appears 15 frames into its progress - the first 15 frames are trimmed off. Inside ``, `useCurrentFrame()` starts at 15 instead of 0. ## Trim the End Use `durationInFrames` to unmount content after a specified duration: ```tsx ``` The animation plays for 45 frames, then the component unmounts. ## Trim and Delay Nest sequences to both trim the beginning and delay when it appears: ```tsx ``` The inner sequence trims 15 frames from the start, and the outer sequence delays the result by 30 frames.
