Good to know
Billing
Runs bill your account credits at provider cost with 0% markup. The submit response includes the credit estimate; failed generations are refunded automatically. Add ?dryRun=1 to get the estimate without running anything.
Errors
Errors are always { "error": { "code", "message" } } with stable codes: unauthorized, model_not_available, invalid_parameter, insufficient_credits, rate_limited. A failed run is not an HTTP error — poll responses report status: "FAILED" with the reason.
What makes Grok Imagine Video 1.5 Image to Video different
Native audio, included in the price
Grok Imagine Video 1.5 generates synchronized audio with every clip in the same pass as the picture, and it's covered by the per-second rate rather than billed as an add-on. You can even direct the soundtrack from the prompt — name the ambience, effects, or mood you want and the model scores the scene to match what happens on screen.
Free-form durations from 1 to 15 seconds
Pick any length from 1 to 15 seconds instead of choosing between a couple of fixed presets. One- and two-second clips make cheap motion tests, six seconds is the sweet-spot default, and 15 seconds is enough for a full beat of action with sound — at 480p, a 15-second draft still costs well under $0.20.
Three resolutions, one cheap draft rung
480p runs at $0.012 per second, 720p at $0.0225, and 1080p at $0.04 — so a 5-second draft costs $0.06 and a 5-second full-HD final $0.20. A practical Scenetra workflow: iterate your prompt at 480p until motion and audio land, then flip the resolution select to 1080p for the final render. Same node, same wiring, and every generation is billed at provider cost with 0% markup.
Eight aspect ratios, or let the model decide
Grok Imagine Video 1.5 outputs 16:9, 4:3, 3:2, 1:1, 2:3, 3:4, and 9:16 — covering widescreen, square, and vertical social formats — or you can leave the ratio on Auto and let the model pick a frame that suits your prompt. That makes it easy to render the same idea as both a landscape hero clip and a 9:16 story cut.

Frequently asked questions
What is Grok Imagine Video 1.5?+
It's xAI's latest image-to-video model: upload a still image, describe the motion in a prompt, and it generates a video of up to 15 seconds at 480p or 720p, with synchronized audio included when generated. xAI describes the 1.5 models as its best image-to-video yet, with improved motion and physics. On Scenetra it runs as a node in the visual workflow editor.
How do I use Grok Imagine to animate a photo?+
On Scenetra: drop a Grok Imagine Video v1.5 node onto your board, upload the photo, write a short prompt describing the motion you want — camera moves, actions, atmosphere — pick a duration and resolution, and generate. No X app or API key needed; it works in the browser.
Does Grok Imagine Video 1.5 generate audio?+
Yes — v1.5 generates synchronized audio with the video, and it's included in the per-second price rather than billed as an add-on. That covers ambient sound and effects that match the animated scene.
How should I prompt Grok Imagine for image to video?+
Describe the motion, not the image — the model already sees your upload. Name the action ('she turns toward the camera'), the camera move ('slow dolly in'), and the mood or sound you want. Short, concrete prompts tend to beat long scene descriptions, and Scenetra's board makes it cheap to iterate at 480p until the motion lands.
