Timeline editing: Multi-track support: video, audio, text, images, shapes Trim, split, join, and rate-stretch clips Pre-compositions for complex scenes Keyframe animation with a Bezier curve editor Undo/redo with full history GPU-accelerated effects: All visual effects run as WebGPU shaders - zero CPU overhead during preview: Blur, sharpen, color correction Distortion, keying (chroma key) 25 blend modes Layer masks Export: Real video export in the browser via WebCodecs - not
