SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Creating video content from scratch requires filming, editing, and production resources. This Skill lets you generate AI videos directly from text prompts or reference images through multiple provider gateways, without managing separate API integrations for each video model. ## Core Features & Use Cases - Multi-Provider Video Generation: Access VEO, Kling, Sora, Runway, Seedance, MiniMax, and LTX models through the HeyGen and fal.ai gateways with a single workflow API. - Text-to-Video and Image-to-Video: Generate clips from text descriptions or animate reference images, with control over aspect ratio (16:9, 9:16, 1:1) and provider-specific configuration. - Async Job Management: Submit generation requests, receive an execution ID, and poll for completion to retrieve the video URL and asset ID. - Use Case: A social media team needs a vertical 9:16 clip of a coffee shop interior for a reel. Submit the prompt with the desired aspect ratio, poll the execution endpoint, and download the finished video. ## Quick Start Ask the agent to generate a 16:9 video of a drone shot flying over a coastal city at sunset using the default provider.

FAQPage Schema
How do I generate an AI video from a text prompt?

Submit a POST request to the HeyGen workflows executions endpoint with workflow_type GenerateVideoNode and your prompt in the input field. You receive an execution_id, then poll the status endpoint every 10 seconds until the video URL is returned.

Which video generation providers are supported?

The HeyGen gateway supports VEO 3.1, VEO 3, VEO 2, Kling Pro, Sora V2, Runway Gen-4, Seedance Pro and Lite, and LTX Distilled. The fal.ai gateway provides Seedance 2.0, Kling v3/v2.1, MiniMax, and VEO models.

Can I generate video from a reference image?

Yes, image-to-video generation is supported by passing a reference_image_url in the request input. You can also provide a tail_image_url to guide the final frame of the generated clip.

What API keys do I need for AI video generation?

You need at least one of two credentials: HEYGEN_API_KEY for the HeyGen multi-model gateway, or FAL_KEY for the fal.ai gateway. Either one alone is sufficient to start generating videos.

How long does AI video generation take?

Video generation is the slowest workflow type and can take up to 5 minutes. Poll the execution status endpoint every 10 seconds and allow a maximum wait of around 600 seconds before treating the job as timed out.

Are generated video URLs permanent?

No, output video URLs are temporary and should be downloaded promptly after completion. The response also includes an asset_id that can reference the video in other HeyGen workflows.
