Motion design studio and frame renderer

OPUS 5.5 + FABLE 5.5 built me a motion design studio, and one function renders all 5,400 frames of the film... two models build the editor, you drag the timing, and every frame in every format comes from the same call brief → draft → drag → render → ship Dario's Opus 5.5 builds the editor in Claude Code: layers, a canvas, an inspector, a timeline, and one function under all of it, renderFrame(project, t) Fable 5.5 drafts the scenes and the first timing from a real brief: 12 references, 2 fonts, 214 words of copy and a logo then a person takes over. choose, drag, refine every decision lands in project.json as a slider value or a keyframe, so it survives the next edit drag the damping from 0.35 to 0.62 and the number changes in the file. nothing gets re-prompted the preview scrubs that one function and the export loops over it. there is no second renderer to disagree with the first a 60 second film at 30 fps is 1,800 frames. the same project fills 16:9, 1:1 and 9:16, so that's 5,400 frames and nobody animates the square cut again the agent placed 38 keyframes, and a person moved 27 of them by hand that's 71% of the timing coming from a human eye. the first guess held on 11 the editor gets built once, and the eye is still needed on every film. one renderer makes the preview equal the export, and it doesn't make the film good one function, 3 formats, 5,400 frames, and 27 of 38 keyframes moved by hand ↓
