Grok Imagine 1.5 API

What is Grok Imagine 1.5 API

Grok Video 1.5 is xAI's latest image-to-video model, built on the Aurora engine. It animates a source image into video, offering improved motion, physics, and temporal consistency compared to the original Grok Video.

How to use Grok Imagine 1.5 API

To use the Grok Video 1.5 API, you will need an API key. You can obtain this by signing up. The process involves sending a POST request to the /v2/videos/generate endpoint with your API key, prompt, and model details. The request requires a source image URL. The API returns a jobId which can be used to poll for the job status, or you can provide a webhook_url to receive the result asynchronously.

Features of Grok Imagine 1.5 API

• Image-to-Video Animation: Animates a still image into a video clip.
• Enhanced Motion and Physics: Offers better motion quality, physics, and temporal consistency.
• Synchronized Audio: Generates synchronized audio, music, and sound effects in the same pass as the video.
• Clip Length Options: Supports durations of 6, 10, or 15 seconds.
• Resolution: Output is 720p.
• Aspect Ratios: Supports 8 aspect ratios, including auto, 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, and 2:3.
• Single API Integration: Works with the same API endpoint, key, and billing as other models.
• Asynchronous Delivery: Supports asynchronous job processing with webhooks.

Use Cases of Grok Imagine 1.5 API

• Animate Any Still: Turn portraits, product shots, and renders into moving clips with believable physics.
• Consistent Aspect Ratios: Generate videos for various placements (feed, story, banner) from a single prompt using 8 supported aspect ratios.
• Character Performance: Maintain stable faces and limbs through gestures and camera moves.
• Flat-Priced Clips: Predictable unit economics for batch campaign work with per-clip pricing.

Pricing

The pricing is based on credits per generation, with costs varying by duration: 84 credits for 6 seconds, 140 credits for 10 seconds, and 210 credits for 15 seconds. This translates to approximately $0.84–$2.10 per clip. Pricing depends on resolution and selected options. Failed jobs are automatically refunded. A single credit balance is used across all Apiframe models. Volume discounts are available.

FAQ

• What is Grok Video 1.5? xAI's newest Grok Video model, built on the Aurora engine. It animates a source image into video with better motion, physics, and temporal consistency than the original Grok Video.
• How is it different from Grok Video? Version 1.5 is image-to-video only and costs more per second, but delivers noticeably better motion and physics. The original model still handles text-only prompts and multi-image reference sets, and is cheaper for drafts.
• Does it need a source image? Yes. Every request takes an image URL alongside the prompt; the image becomes the opening frame and, unless you override the aspect ratio, sets the output shape.
• How long are the clips and what resolution? Choose 6, 10, or 15 seconds. Output is 720p.
• Does it generate audio? Yes. Synchronized audio, music, sound effects, and ambience, is produced in the same pass as the video.
• What does it cost? 84 credits for 6 seconds, 140 for 10 seconds, and 210 for 15 seconds, drawn from the same balance as every other Apiframe model.
