+# Video Generation Guide
+
+## CLI usage
+
+```bash
+# Basic
+python scripts/minimax_video.py "A cat playing piano in a cozy room" -o cat.mp4
+
+# With camera control
+python scripts/minimax_video.py "Ocean waves crashing on rocks [Truck left]" -o waves.mp4
+
+# 10 seconds, 1080P
+python scripts/minimax_video.py "City skyline at sunset [Push in]" -o city.mp4 --duration 10 --resolution 1080P
+
+# Disable prompt auto-optimization
+python scripts/minimax_video.py "Exact prompt I want used" -o out.mp4 --no-optimize
+```
+
+## Programmatic usage
+
+```python
+from minimax_video import generate, create_task, poll_task, download_video
+
+# Full pipeline (blocking)
+generate("A cat playing piano", "cat.mp4", model="MiniMax-Hailuo-2.3", duration=6)
+
+# Step by step
+task_id = create_task("A cat playing piano")
+file_id = poll_task(task_id, interval=10, max_wait=600)
+download_video(file_id, "cat.mp4")
+```
+
+## Models
+
+| Model | Resolution | Duration | Notes |
+|-------|-----------|----------|-------|
+| `MiniMax-Hailuo-2.3` | 768P, 1080P | 6s, 10s (768P only) | Latest, recommended |
+| `MiniMax-Hailuo-02` | 768P, 1080P | 6s, 10s (768P only) | Previous gen |
+| `T2V-01-Director` | 720P | 6s | Camera control optimized |
+| `T2V-01` | 720P | 6s | Base model |
+
+## Camera commands
+
+Insert `[Command]` in prompt text to control camera movement:
+
+| Command | Effect |
+|---------|--------|
+| `[Truck left]` | Camera moves left |
+| `[Truck right]` | Camera moves right |
+| `[Push in]` | Camera moves toward subject |
+| `[Pull out]` | Camera moves away from subject |
+| `[Pan left]` | Camera rotates left (fixed position) |
+| `[Pan right]` | Camera rotates right (fixed position) |
+| `[Tilt up]` | Camera tilts upward |
+| `[Tilt down]` | Camera tilts downward |
+| `[Pedestal up]` | Camera rises vertically |
+| `[Pedestal down]` | Camera lowers vertically |
+| `[Zoom in]` | Lens zooms in |
+| `[Zoom out]` | Lens zooms out |
+| `[Static shot]` | No camera movement |
+| `[Tracking shot]` | Camera follows subject |
+| `[Shake]` | Handheld shake effect |
+
+Example: `"A runner sprints through a forest trail [Tracking shot]"`
+
+## Pipeline
+
+The script handles the full async flow:
+
+1. **Create task** — `POST /v1/video_generation` → returns `task_id`
+2. **Poll status** — `GET /v1/query/video_generation?task_id=xxx` → poll until `Success`
+   - Status values: `Preparing` → `Queueing` → `Processing` → `Success` / `Fail`
+3. **Download** — `GET /v1/files/retrieve?file_id=xxx` → get `download_url` (valid 1 hour) → save file
+
+Typical generation time: 1–5 minutes depending on duration and resolution.
+
