# Engine routing

1. Read the scene layers and required capabilities from Canonical Video IR.
2. Route kinetic typography, 2D graphics and data visuals to HyperFrames + GSAP.
3. Route complex compositing, tracking and VFX to After Effects.
4. Route simulation, product visualization and 3D scenes to Blender.
5. Route WebGL shaders and interactive procedural 3D to Three.js.
6. Use Premiere Pro for editorial assembly and FFmpeg for media processing and delivery.
7. Verify engine availability. Never silently substitute an unavailable required engine.
8. Record the selected engine, reason, dependencies and output contract for every task.
