## What this is

A web app for choosing and writing camera moves for AI video platforms that expose NAMED presets.
It does not generate video and it never fires a job. It writes the prompts you take to the
platform yourself.

Not affiliated with or endorsed by Higgsfield or OSideMedia. The catalogue below is a release-time
snapshot of the upstream skill set, not a live feed.

## The free part

The checker needs no account, spends no credits, and runs entirely in your browser. Paste or write
a prompt and it reports:

- **Stacked moves - the One-Move Rule.** More than one primary move in a single shot. Named
  upstream as the single biggest cause of jitter, unwanted rotation and failed generations. Two
  moves are legal only as one of four sanctioned combinations, or as phases with explicit timing.
- **Contradictory moves.** A push and a pull, a rise and a fall. The camera cannot do both.
- **A move that cannot reach its framing.** A stated 10cm travel with a wide-to-extreme-close-up
  framing change is internally impossible; the model renders one side and improvises the other.
- **A duration outside its shot type band**, including the one people get wrong: a flash
  establishing shot is 0.3-0.5s, not a full second.
- **Zoom written for a physical move.** `zoom` is a lens change; a travelling camera is a dolly,
  track, push-in or pull-out. Crash Zoom and Dolly Zoom are catalogue presets and are exempt.
- **A slow move with no stated distance**, or a distance with no stated time - either gets
  oversold by the model.
- **FACS problems**: an action unit outside the reference (which renders as nothing at all), more
  than the three-to-four expression ceiling, beats that do not sum to the duration, a beat
  schedule under more than one camera move, and codes with no scene around them.

## The five lanes

| Lane | `task` | What it produces |
| --- | --- | --- |
| Move selection | `pick` | A shortlist with the exact prompt phrases, the moves ruled out and why, one chosen move, a duration plan |
| Shot prompt | `shot` | A move plan, the prompt, and the framing check run in both directions |
| Performance schedule | `face` | A FACS beat schedule, the prompt, and the limits check |
| Shot list | `list` | A shot list whose durations respect the bands and sum to the envelope |
| Take triage | `fix` | One of five verdicts, the cause, one variable to change, and a revised prompt |

## Sources

Lanes are derived from https://github.com/OSideMedia/higgsfield-ai-prompt-skill, an open-source MIT
skill set of 34 sub-skills: higgsfield-camera, higgsfield-facs, higgsfield-troubleshoot,
higgsfield-shotlist-director and higgsfield-motion.

## API

Full docs with worked examples in eight languages: https://camera-move-desk.skillsafe.ai/api.html

Base URL `https://api.skillsafe.ai/v1/app-api`. Bearer token from
https://camera-move-desk.skillsafe.ai/tokens.html. Every run body must carry a `task` field naming
the lane; the body **is** the input object and must not be wrapped in `{"input": ...}`.
`GET /me` and `POST /estimate` are free; `POST /run` and `POST /run-stream` are metered.

`move` must be a catalogue name spelled exactly. `shot_type` is what turns the duration band from
a guess into a check.

## Pricing

Runs are metered and priced per model - `gpt-5.6-luna`, `gpt-5.6-terra` (default) or `gpt-5.6-sol`.
`POST /estimate` returns the worst-case reservation for free before anything is spent. The checker
and every lane worked example cost nothing.
