What to Build with OpenClaw + InfiniteTalk
-
Podcast-to-video conversion
Feed podcast audio and a host photo to generate a talking avatar video, turning audio-only episodes into visual content for YouTube or social media.
-
Educational and tutorial videos
Create lecture or tutorial videos from a single instructor photo and recorded narration, producing talking-head content without a camera setup.
-
Digital spokesperson for marketing
Build a branded digital presenter from one reference image, then produce spokesperson videos in several languages by swapping the audio track.
Why Use InfiniteTalk Through RunAPI + OpenClaw
-
1 variants, one API key
Use one RunAPI connection to choose among the live model variants without changing your integration.
-
Clear usage pricing
See current catalog pricing before you send a request, with no subscription or minimum spend required.
-
Automatic task workflows
Submit, poll, and collect asynchronous results through a consistent task workflow without writing manual polling code.
OpenClaw + InfiniteTalk Questions
Can I use InfiniteTalk in OpenClaw?
Yes. Once RunAPI is set up as a provider in OpenClaw, the agent can send InfiniteTalk tasks with an audio file and a reference image using the same RunAPI API key it uses for other models.
How long can an InfiniteTalk video be?
The output length follows the source audio. InfiniteTalk animates the reference image for the full duration of the speech track you provide.
What happens while the video is being generated?
InfiniteTalk runs as an asynchronous task. RunAPI returns a task ID right away, and OpenClaw can poll the task or receive a callback when the video is ready.
Which model ID should I use?
Choose a public model ID from the version table. Each ID exposes the endpoints shown for that version.
Does this guide configure a chat model?
No. This Model Line uses the endpoint workflow shown here and is not presented as an agent chat model.
