# Product Video Capture Produce reusable clean masters first; derive presentation from them later. Preserve the raw master and camera config so every camera choice is reversible. ## Prerequisites And Repo Discovery - Require Linux Xvfb, Chrome for Testing, Playwright/CDP, FFmpeg/FFprobe, a Kandev checkout with E2E fixtures, and the landing repository. - Resolve the Kandev root with `git rev-parse --show-toplevel`, then verify it contains `scripts/dev-isolated` and `apps/web/e2e/`. - Resolve the landing root from `KANDEV_LANDING_REPO` when set and verify it contains both `scripts/product-loop-camera.mjs` and `scripts/product-loop-encoder.mjs`. If the variable is unset or its path fails verification, search the available workspace and sibling checkouts for both marker files; do not select a directory by name alone. - If discovery finds zero or multiple landing candidates, ask the user to identify the checkout. Record the resolved roots as `KANDEV_REPO` and `LANDING_REPO`, and use those variables for every command and copy operation. ## Choose Deliverable | Request | Path | | --- | --- | | New feature/story | Seed with `/product-demo-seeding`, then capture desktop and mobile masters | | Different zoom/crop/pacing | Invoke `/product-demo-seeding` to re-prove source/isolation/provenance, then reuse an approved raw master and change camera config only | | New poster/static image | Extract a settled pointer-free frame from approved master or recapture native screenshot | | Long...
