## Description

Calibrates pre-recorded `cam_*.mp4` datasets through the AutoMagicCalib REST API. Use for user-supplied local MP4s; route live RTSP streams to `amc-run-rtsp-calibration`.

# Skill: Calibrate from Video Files

## When to Use This Skill

Activate this skill when the user has pre-recorded MP4 files and wants to calibrate them via the AMC REST API. Typical prompts:

- "calibrate my videos" / "run AMC on these videos"
- "calibrate from video files"

Drives calibration through the REST API on user-supplied **pre-recorded MP4 files**, no CLI scripts or Docker bind-mounts required, just a running microservice and your files.

Do not use this skill for live RTSP streams or `rtsp://...` URLs; route those requests to `skills/amc-run-rtsp-calibration/SKILL.md`.

## Purpose

Guide the agent through project creation, sorted MP4 upload, local asset resolution, UI fallback only when necessary, project verification, calibration, polling, evaluation, and optional VGGT refinement for a user-provided multi-camera dataset.

## Prerequisites

- [ ] AMC microservice **and** UI running (follow `skills/amc-setup-calibration-stack/SKILL.md`)
- [ ] You know the microservice URL (use `https://<HOST_IP>:<MS_PORT>` for remote AMC, or `http://localhost:<MS_PORT>` on loopback) and UI URL
- [ ] Video files locally as contiguous `cam_00.mp4`, `cam_01.mp4`, … time-synchronized, ~1920×1080
- [ ] Python 3 with `requests`
- [ ] If AMC stores project outputs outside the default `projects/` directory, you know the host `PROJECTS_DIR`

## Interaction Model

- The "host's question mechanism" means the runtime's built-in prompt API for short user decisions, such as terminal stdin, an IDE ask tool, or an equivalent interactive dialog.
- If that mechanism is unavailable, ask in chat and wait before any guarded step that requires user confirmation or a missing-file decision.
- For unattended runs, the bundled script requires all non-UI inputs up front and exits before `/calibrate` unless `CONFIRM_CALIBRATION=true` is set. `RUN_VGGT=true` remains a separate opt-in for the optional VGGT step.
