Master motion-designer playbook for composing premium films with compose_motion — the decision process, optical composition, rhythm, restraint, transition craft, the physics of premium motion, worked examples with the reasoning exposed, and the failure modes to avoid. Read this BEFORE composing any motion piece (launch film, product reel, title sequence, brand sting).
Cut and animate to the music — get beats/onsets with analyze_audio, then land cuts and zoom/scale punches on the beat.
Plan and place B-roll cutaways over an A-roll talking track — from the media library or generated (BYOK).
The non-negotiable way to work — build every edit ON the Kaestral timeline via MCP tools so the user watches it happen, and render only with Kaestral's own Export. Read this before any editing task.
Apply modern short-form caption looks — word-pop, karaoke highlight, bold-boxed, typewriter — sized and placed for 9:16.
Give a clip or project a cohesive designed look — extract the palette, build a color grade, and choose on-brand type and captions.
Package the finished edit for each platform — Reels/TikTok/Shorts (9:16), feed (1:1), YouTube (16:9) — with the right aspect, safe areas, duration, and captions, then export from Kaestral.
Build a short promo or ad from a product/topic — hook, 2–4 benefit beats, and a clear call-to-action — using titles, captions, music, and pacing. Use for "make a promo / ad / product video".
