Runway Video API for source-image animation

Find Runway Video API guides for Gen-4 Turbo workflows through SeeAPI. Review source-image requirements, describe motion and retrieve the generated shot.

Working with the Runway Video API

  1. 1

    Prepare the shot’s visual starting point

    Open the Runway task matching your source material. For image-led generation, choose an image that expresses the composition you want the video to begin with.

  2. 2

    Focus the prompt on movement

    Describe subject action and camera behavior. Check the document for supported clip controls and keep them separate from the creative brief.

  3. 3

    Evaluate the clip in context

    Review the generated shot with the source image and motion instruction. Integrate the documented task and retrieval flow before connecting the result to an editing workflow.

Runway Video API: practical questions

Which Runway model is covered by my request?

Use the model identifier shown in the individual SeeAPI guide. A Runway account or brand name does not select a particular video model.

Can I send any source image?

Check the selected task’s accepted image format and other input requirements. Prepare the asset accordingly before submitting the request.

Can I copy a direct Runway SDK example?

Use the SeeAPI guide for this integration. Its request envelope and authentication may differ from a direct Runway call.

How should I compare motion prompts?

Keep the source image and endpoint fixed, then vary the motion instruction. This makes prompt changes easier to assess separately from model changes.
