Runway video generation setup in OpenClaw	Runway	You want to use Runway video generation in OpenClaw You need the Runway API key/env setup You want to make Runway the default video provider

OpenClaw ships a bundled runway provider for hosted video generation, enabled by default, registered against the videoGenerationProviders contract.

Property	Value
Provider id	runway
Plugin	bundled, enabledByDefault: true
Auth env vars	RUNWAYML_API_SECRET (canonical) or RUNWAY_API_KEY
Onboarding flag	--auth-choice runway-api-key
Direct CLI flag	--runway-api-key <key>
API	Runway task-based video generation (GET /v1/tasks/{id} polling)
Default model	runway/gen4.5

Getting started

```bash openclaw onboard --auth-choice runway-api-key ``` ```bash openclaw config set agents.defaults.mediaModels.video.primary "runway/gen4.5" ``` Ask the agent to generate a video. Runway will be used automatically.

Supported modes and models

The provider exposes seven Runway models split across three modes. The same model id can serve more than one mode (for example gen4.5 works for both text-to-video and image-to-video).

Mode	Models	Reference input
Text-to-video	gen4.5 (default), veo3.1, veo3.1_fast, veo3	None
Image-to-video	gen4.5, gen4_turbo, gen3a_turbo, veo3.1, veo3.1_fast, veo3	1 local or remote image
Video-to-video	gen4_aleph	1 local or remote video

Local image and video references are supported via data URIs.

Aspect ratios	Allowed values
Text-to-video	16:9, 9:16
Image and video edits	1:1, 16:9, 9:16, 3:4, 4:3, 21:9

Video-to-video currently requires `runway/gen4_aleph`. Other Runway model ids reject video reference inputs. Picking a Runway model id from the wrong column produces an explicit error before the API request leaves OpenClaw. The provider validates `model` against the mode's allowlist (`TEXT_ONLY_MODELS`, `IMAGE_MODELS`, `VIDEO_MODELS`) in `extensions/runway/video-generation-provider.ts`.

Configuration

{
  agents: {
    defaults: {
      mediaModels: {
        video: {
          primary: "runway/gen4.5",
        },
      },
    },
  },
}

Advanced configuration

OpenClaw recognizes both `RUNWAYML_API_SECRET` (canonical) and `RUNWAY_API_KEY`. Either variable authenticates the Runway provider. Runway uses a task-based API. After submitting a generation request, OpenClaw polls `GET /v1/tasks/{id}` until the video is ready. No additional configuration is needed for the polling behavior.
