Keyframe animation works on video, not just stills.
Load a clip, toggle Animate, and keyframe the whole effect chain along it — clean at the start, hammered by the end, a tracking error sweeping through the middle. Export applies the animation frame by frame.
- The timeline replaces the transport bar on video. Same play button and scrubber, with the keyframe track underneath — the playhead is the video position, so scrubbing it seeks the footage and there aren't two scrubbers disagreeing about where you are.
- Length and frame rate come from the clip, shown rather than editable, since the source dictates both. Keyframe times stay proportional, so a preset saved from a still applies to a clip with its keys spread along it.
- Everything that worked on stills still does: keys hold parameters you didn't touch, editing while parked on a keyframe updates it in place, and per-keyframe easing is unchanged.
