## Description

AI video generation via Fal.ai, Seedance 2.0, Kling, MiniMax Hailuo, xAI Grok Imagine, and OFox. Use when the user wants to generate a video clip, text-to-video, image-to-video, first/last-frame transitions, reference-guided generation, multi-shot, or generatively editing / extending an existing clip.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# Video Gen

Submits one video generation job per call and returns a `jobId`. Job management (wait / status) belongs to `track_progress`; this skill does **not** place videos on the timeline automatically.

## When to Use

Any time the user wants to generate a video clip, text-to-video, image-to-video, first-last-frame transition, reference-based generation, multi-shot storyboard, or generatively editing / extending an existing video (producing new generated footage based on a source clip; not timeline trimming).

## Models

| Model | Reference | Strengths |
| --- | --- | --- |
| `fal` + `falModel` | [references/fal.md](references/fal.md) | Explicit Fal catalog; see tool schema for per-model limits |
| `seedance2` | [references/seedance2.md](references/seedance2.md) | Default when configured. Multimodal refs, first/last, edit/extend/bridge, 2, 15s, 480p/720p/1080p/4k, audio/seed/camera/watermark/last-frame/task controls. |
| `kling` | [references/kling.md](references/kling.md) | Technical camera/performance; Omni multi-shot; images ≤7 (≤4 with one feature `refVideos`); std/pro; 3, 15s. |
| `hailuo` | [references/hailuo.md](references/hailuo.md) | MiniMax 海螺. T2V / I2V / first+last; **6s or 10s**; 512P (Hailuo-02), 720p→768P, 1080P (6s); no multi-ref / multi-shot. |
| `grok-imagine-video` | [references/grok-imagine-video.md](references/grok-imagine-video.md) | xAI Grok Imagine. Text-to-video only; 1, 15s; 480p/720p/1080p; audio track included. |
| `ofox` | [references/ofox.md](references/ofox.md) | OFox multi-model gateway (Seedance/Wan and more behind one key). Text/image-to-video, first+last frame, up to 9 image refs; 2, 30s with per-model API limits; 480p/720p/1080p per model. |

**IMPORTANT:** Before generating, READ the chosen model's reference for capabilities, input channels, modes, prompt structure, and model-specific behavior. Never invent params the reference forbids.
