Generate AI videos from text prompts using multiple provider gateways. Use when: (1) Generating videos from text descriptions, (2) Creating AI-generated video clips for content production, (3) Image-to-video generation with a reference image, (4) Choosing between video generation providers (VEO, Kling, Sora, Runway, Seedance, MiniMax, Gemini Omni). Supports gateways: HeyGen API, fal.ai API, Kling official direct API, and the Gemini API (Gemini Omni Flash).

Generate AI videos from text prompts. Supports multiple providers via four API paths:
| Gateway | Env Variable | Providers | Tool |
|---|---|---|---|
| fal.ai | FAL_KEY | Seedance 2.0 (standard + fast), Kling v3/v2.1, MiniMax, VEO | seedance_video, kling_video, minimax_video, veo_video |
| HeyGen | HEYGEN_API_KEY | VEO 3.1, Kling Pro, Sora v2, Runway Gen-4, Seedance Pro / Lite (1.x) | heygen_video |
| Kling Official | KLING_API_KEY | Kling official Classic, Turbo, and basic Omni video | kling_official_video |
| Gemini API | GEMINI_API_KEY / GOOGLE_API_KEY | Gemini Omni Flash (generation + conversational editing) | gemini_omni_video |
Iterative editing — Gemini Omni. When the brief calls for refining an existing clip (add/remove objects, restyle, change lighting or on-screen text) rather than regenerating, Gemini Omni Flash is the only provider in the fleet with stateful multi-turn editing. See Layer 3 gemini-omni for the authoritative prompting guide (reference-image tags, timecode syntax, edit-prompt rules) before writing any prompt for it.
Preferred premium default — Seedance 2.0. When any premium gateway is configured (FAL_KEY → seedance_video, or HeyGen's Video Agent / Avatar Shots path), Seedance 2.0 is the preferred default for cinematic, trailer, and high-fidelity clip work. It is the only model in the fleet with single-pass native synchronized audio, multi-shot generation, director-level camera control, and lip-sync from quoted dialogue, and it ranks #1 on Artificial Analysis Elo as of early 2026. Switch off it only when the user has a specific reason (budget, provider preference, stylistic fit like VEO for photoreal landscape or Kling for specific anime look). See Layer 3 seedance-2-0 for the authoritative prompting and parameter guide.
IMPORTANT: Always use video_selector instead of calling provider tools directly. The selector handles availability checks, cost comparison, and automatic fallback, and its scoring engine already biases toward Seedance 2.0 for cinematic intent.
Use whichever configured gateway best matches the user's available providers and cost/quality goals.
HEYGEN_API_KEY to access the multi-model gateway.FAL_KEY to access Kling, MiniMax, and Veo through fal.ai.KLING_API_KEY to access Kling's official direct API via provider="kling_official".GEMINI_API_KEY or GOOGLE_API_KEY to access Gemini Omni video generation and conversational editing.Do not describe any gateway as the default or top choice without checking the registry and current task fit first.
fal.ai Kling (kling_video, provider="kling") and Kling Official (kling_official_video, provider="kling_official") are different paths. Do not reuse fal.ai queue URLs, FAL_KEY, or image upload behavior when the official provider is selected.

# Video Generation (Multi-Gateway)
Generate AI videos from text prompts. Supports multiple providers via four API paths:
| Gateway | Env Variable | Providers | Tool |
|---------|-------------|-----------|------|
| **fal.ai** | `FAL_KEY` | **Seedance 2.0** (standard + fast), Kling v3/v2.1, MiniMax, VEO | `seedance_video`, `kling_video`, `minimax_video`, `veo_video` |
| **HeyGen** | `HEYGEN_API_KEY` | VEO 3.1, Kling Pro, Sora v2, Runway Gen-4, Seedance Pro / Lite (1.x) | `heygen_video` |
| **Kling Official** | `KLING_API_KEY` | Kling official Classic, Turbo, and basic Omni video | `kling_official_video` |
| **Gemini API** | `GEMINI_API_KEY` / `GOOGLE_API_KEY` | Gemini Omni Flash (generation + conversational editing) | `gemini_omni_video` |
**Iterative editing — Gemini Omni.** When the brief calls for *refining an existing clip* (add/remove objects, restyle, change lighting or on-screen text) rather than regenerating, Gemini Omni Flash is the only provider in the fleet with stateful multi-turn editing. See Layer 3 `gemini-omni` for the authoritative prompting guide (reference-image tags, timecode syntax, edit-prompt rules) before writing any prompt for it.
**Preferred premium default — Seedance 2.0.** When any premium gateway is configured (`FAL_KEY` → `seedance_video`, or HeyGen's Video Agent / Avatar Shots path), Seedance 2.0 is the preferred default for cinematic, trailer, and high-fidelity clip work. It is the only model in the fleet with **single-pass native synchronized audio, multi-shot generation, director-level camera control, and lip-sync from quoted dialogue**, and it ranks #1 on Artificial Analysis Elo as of early 2026. Switch off it only when the user has a specific reason (budget, provider preference, stylistic fit like VEO for photoreal landscape or Kling for specific anime look). See Layer 3 `seedance-2-0` for the authoritative prompting and parameter guide.
**IMPORTANT:** Always use `video_selector` instead of calling provider tools directly. The selector handles availability checks, cost comparison, and automatic fallback, and its scoring engine already biases toward Seedance 2.0 for cinematic intent.
## Authentication
Use whichever configured gateway best matches the user's available providers and cost/quality goals.
- **HeyGen:** Set `HEYGEN_API_KEY` to access the multi-model gateway.
- **fal.ai:** Set `FAL_KEY` to access Kling, MiniMax, and Veo through fal.ai.
- **Kling Official:** Set `KLING_API_KEY` to access Kling's official direct API via `provider="kling_official"`.
- **Gemini API:** Set `GEMINI_API_KEY` or `GOOGLE_API_KEY` to access Gemini Omni video generation and conversational editing.
Do not describe any gateway as the default or top choice without checking the registry and current task fit first.
fal.ai Kling (`kling_video`, `provider="kling"`) and Kling Official (`kling_official_video`, `provider="kling_official"`) are different paths. Do not reuse fal.ai queue URLs, `FAL_KEY`, or image upload behavior when the official provider is selected.
```bash

"aspect_ratio": "9:16",
"provider": "veo_3_1"
}
}
```
### Fast Generation with LTX
```json
{
"workflow_type": "GenerateVideoNode",
"input": {
"prompt": "Abstract colorful shapes morphing and flowing",
"provider": "ltx_distilled"
}
}
```
## Best Practices
1. **Be descriptive in prompts** — include camera movement, lighting, style, and mood details
2. **Default to Seedance 2.0 (via `seedance_video`) for cinematic and motion-led work** when `FAL_KEY` is set — single-pass synced audio, multi-shot, lip-sync, director-level camera. Use VEO 3.1 / Sora V2 Pro when the user specifically wants Google or OpenAI motion character; use `ltx_distilled` or `veo3_fast` only when speed is the hard constraint
3. **Use reference images** for image-to-video generation — great for animating product photos or still images
4. **Video generation is the slowest workflow** — allow up to 5 minutes, poll every 10 seconds
5. **Aspect ratio matters** — use `9:16` for social media stories/reels, `16:9` for landscape, `1:1` for square
6. **Output includes `asset_id`** — use this to reference the generated video in other HeyGen workflows
7. **Output URLs are temporary** — download or save generated videos promptly
