Cut twelve frames from a reaction. Slip the sound ahead of the picture. Change what the audience knows before a character speaks. The timing, the camera, the motion, the continuity, the behavior are all working parts of the representation. Editing them changes what the next model receives, what it can infer, and what a coding agent can build. No need to spend thousands of tokens trying to describe what the moving image and synchronized audio already make available.

Reactor generates new video and sound while media strand processing keeps sources, edits, branches, references and results in play. Strands agents work across those representations, code and runtime behavior. Take apart an expensive application. Trace the function that earns its fees. Reconstruct it, run the original and the new implementation against one another, find the differences and keep working. The investigation is already audiovisual programming, and the programming is producing the next generation of tools.

The same production yields structured rich-media specifications for coding agents. Frames preserves visual sequences and their timing. Transcript carries language in context. Skill carries working procedures, code and reference assets into further execution.

A film edit can change how a model understands a scene. A reconstructed interface can become an independent application. A recorded technique can become an executable skill. The work can branch, recombine and continue while its audiovisual production reaches an audience. What used to disappear into model inference or remain trapped inside proprietary software becomes material that can be inspected, edited, reproduced and put straight back to work.
