add_video_keyframe
Add an animation keyframe to the current AgentCut video project. Keyframes can animate text-layer position, scale and opacity or animate the video frame's position and scale. Use multiple keyframes at different timestamps to create motion, fades, zooms and pans. The visible preview and timeline update immediately.
