Grok Video API
Video APIHOTGrok Video API gives teams an API-first way to use Grok Imagine video generation inside production workflows. It supports prompt-driven text-to-video, reference-based image-to-video, video upscaling, and video extension from one model family.
Use the playground to validate prompts, source images, task IDs, duration, aspect ratio, and payload behavior before connecting Grok video generation to your app, creative tool, or content pipeline.
Lowest cost starts at $0.08/s
480p: 16 credits/s - Image to Video - Output seconds × 16
720p: 28 credits/s - Image to Video - Output seconds × 28
USD estimates use $0.005/credit with the best annual plan. Final billing follows the selected Grok video variant and output settings.
Core request fields
Use a predictable payload for prompts, image URLs, source task IDs, aspect ratio, and callback settings.

The page follows the same API-first structure as the reference: test the model, understand the fields, then move into integration.
Text-to-video generation
Turn detailed prompts into short-form video concepts for social posts, ads, product moments, and fast creative exploration.
Image-to-video motion
Animate source images while preserving the subject, composition, and visual direction that your team already approved.
Upscale and extend
Improve successful Grok clips with video upscaling, or continue an existing generation with an extension task.
API-ready payloads
Work with model IDs, prompts, image URLs, task IDs, aspect ratios, callbacks, and task polling in one integration path.
From Grok video test to production request
A compact path for teams that want to validate output quality before wiring Grok video generation into an app.
1. Choose a mode
Select text-to-video for prompt-only creation, image-to-video for source image animation, or a follow-up mode for upscale and extend.
2. Submit generation
Call the API with your account key, model ID, prompt, optional image URLs or source task ID, and callback URL.
3. Poll and reuse
Track the task until it succeeds, then reuse the output URL in your product, campaign workflow, or follow-up video task.
What you can create with Grok Video API
Use the API when your product needs repeatable Grok video output, not just one-off manual generations.
Successful Grok video generations from the community
Browse public Grok video outputs that finished successfully, then open any case to inspect the prompt, settings, and result.

Grok Imagine Text to Video
Intense one-on-one wizard duel on a crumbling stone bridge over a misty gorge at dusk. A young witch with wind-swept hair in a grey robe faces a tall dark wizard in a tattered black cloak. Her wand erupts a beam of brilliant gold light, his a stream of jet-black smoke. The two beams lock in the middle, throwing violent sparks and bending the air with heat distortion, bridge stones lifting and cracking under the magical pressure. Camera: orbiting steadicam shot around the locked beams, ending in a slow-motion close-up on her determined face lit by the golden glow. Photorealistic live-action fantasy film look, anamorphic lenses, shallow depth of field, cinematic color grading with slightly boosted saturation, rich teal-and-amber tones, volumetric light, film grain. No cartoon, no anime, no CGI look, no text, no watermark.

Built for real Grok video API workflows
Account-gated execution
Users sign in, submit jobs, and consume credits through the existing SdanceAI generation flow.
Reference and task inputs
Image-to-video accepts source image URLs, while upscale and extend workflows can continue from completed video task IDs.
Mode-aware iteration
Start with text or image generation, then move promising outputs into upscale or extension workflows when needed.
Grok Video API questions
What is Grok Video API best for?
It is best for repeatable short-form video generation, including prompt-led clips, animated source images, video variants, upscaled outputs, and extended creative sequences.
Which Grok video modes are available?
The current page exposes Grok Imagine Text to Video, Grok Imagine Image to Video, Grok Imagine Video Upscale, and Grok Imagine Video Extend.
What is the difference between Text to Video and Image to Video?
Text to Video starts from a prompt only. Image to Video uses one or more source images plus a prompt, which is better when you need subject or composition continuity.
When should I use upscale or extend?
Use upscale when you already have a successful Grok video and want a higher-quality version. Use extend when you want to continue a completed generation into a longer sequence.
Where can I test it before integrating?
Use the playground on this page to test prompts, image URLs, source task IDs, aspect ratios, callbacks, and API payload behavior before moving into production.
Does the API support callbacks?
Yes. The request schema includes callback settings where supported, so your service can receive task completion notifications.
Can I use Grok Video API for commercial workflows?
This page is configured for production video workflows. For commercial use, review your account plan, credit balance, model availability, and applicable content policy requirements.
Can I animate an existing product image?
Yes. Use the image-to-video mode with a source image URL and a prompt that describes the motion, camera behavior, and final visual direction.
How should I manage cost?
Start with quick prompt or image-to-video tests, then reserve upscale and extension tasks for clips that are already close to your target.
Can I inspect the actual API fields?
Yes. Select a Grok video mode on this page and the request JSON, field list, and pricing panel will update to match that model.
Turn Grok video into your production workflow
Open the generator, test a Grok video prompt or source image, then use the API docs when you are ready to wire it into production.
