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.
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.

Follow the build-in-kaestral house rule: every cutaway is placed ON the Kaestral timeline via tools, and any b-roll you generate is imported + placed (generate_video/generate_image auto-place; external files via import_media + add_clips) — never assembled into a standalone file. Finish with export_project(mode:"video").
B-roll hides cuts, illustrates the point, and adds visual variety. Goal: overlay relevant cutaways on top of the A-roll at the right moments.
get_timeline for the main (A-roll) clips; get_media for what's already in the library.get_transcript on the A-roll → word-level text + timestamps. Now you can place a cutaway exactly when a topic is mentioned (e.g. B-roll of coffee the moment "coffee" is said).see_video on the A-roll (and on library clips) to read the actual content — so your cutaways match the subject and don't clash with what's on screen.Two sources:
get_media whose names/metadata match the moment. search_media (semantic) isn't available, so match on names + your understanding of the content.generate_video or generate_image a cutaway to order (e.g. "close-up of coffee being poured, cinematic"). It auto-imports and places. Tell the user this costs per clip.set_clip_properties volume 0, or it's silent already).add_clips / insert_clips the B-roll at the target frames; length ~1.5–3s per cutaway.set_keyframes scale/position) to stills.extract_palette + apply_color so B-roll doesn't clash with the A-roll look.beat-sync-cutting).List each moment, the B-roll you placed (library vs generated), and why. Flag anything that needed a transcript/topic you didn't have.
