Lock the Frame. Let the Scene Speak.
Direct coherent motion, dialogue, ambience and effects from one composed starting image.
Grok Imagine Video 1.5 is xAI’s video generation model for turning a composed starting frame into a short scene with improved motion and sound generated in the same pass.
Give One Frame Motion and Sound—at 150 Credits a Second.
Start from a composed image, direct the action and soundscape, then generate from GlobalGPT’s 1-second/720p default configuration—or stretch the same shot out to 15 seconds.
Sound: tiny gears and rain on glass. No dialogue.
Compare Current Default Configurations
GlobalGPT credits checked on 20 August 2026. Defaults differ, so this is a practical starting-price comparison—not a strict like-for-like ranking.

Three Decisions Before Generate
Keep the source frame, movement and sound responsibilities separate.
Upload the Finished Frame
Choose the subject, geometry, lighting and crop to preserve.
Describe What Changes
Name the subject action and one camera behavior.
Direct the Soundscape
Specify dialogue, effects, ambience, music or silence.
Proof You Can See—and Hear
Each scene isolates a different production problem.
Let Small Motions Shape the Scene
Rain trails, warm reflections and a still cup hold one stable composition.
Let the Performance Breathe
A spoken line, natural pause and train ambience arrive in one restrained scene.
Make Every Product Cue Land
A lever click, steam hiss and pour align to a clean commercial shot.
Build a World Beyond the Frame
Wind, traffic, a metal chime and first rain give the rooftop spatial depth.
From Shot Idea to the Next Variation
This workflow belongs to GlobalGPT, not natively to the featured model.
Develop the concept and shot direction.
Generate or upload the approved composition.
Add motion and sound with Grok Imagine Video 1.5.
Keep refining with other GlobalGPT tools.
When the First Frame Matters
Use the model when art direction should be settled before animation.
Carry a chosen look into controlled movement.
Turn one composition into readable story action.
Keep form stable while motion and sound sell.
Grok Imagine Video 1.5 FAQ
What Is Grok Imagine Video 1.5?
Grok Imagine Video 1.5 is xAI's image-to-video model for adding motion and synchronized sound to a composed starting frame. xAI's official documentation describes improvements to motion, physics, effects, ambience and dialogue.
How Much Does Grok Imagine Video 1.5 Cost?
On GlobalGPT, Grok Imagine Video 1.5 is billed at 150 credits per second regardless of resolution, so the 1-second page default costs 150 credits, a 5-second clip costs 750 and the 15-second maximum costs 2,250. Current page defaults list 800 credits for Seedance 2.0 Fast and 1,500 credits for Veo 3.1, but their default configurations differ, so this is not a strict like-for-like ranking. Separately, xAI's official API rates are $0.08/s at 480p, $0.14/s at 720p and $0.25/s at 1080p; supplier API prices are not GlobalGPT credits.
How Fast Is Grok Imagine Video 1.5?
xAI reports about 25 seconds for a 6-second, 720p result in Fast mode. This is an xAI official benchmark, not a GlobalGPT timing test or proof that Grok Imagine Video 1.5 is faster than every competing model.
What Inputs, Durations, Resolutions and Audio Options Can I Use?
Grok Imagine Video 1.5 accepts up to one reference image, durations from 1 to 15 seconds and 720p or 480p output in the GlobalGPT catalog checked on 20 August 2026, plus the aspect ratios listed in the workspace. xAI says effects, ambience and dialogue can be generated in the same pass; browser playback normally starts muted, so use the sound control to hear the track.
Who Should Use Grok Imagine Video 1.5, and How Does It Fit Into GlobalGPT?
Grok Imagine Video 1.5 is best suited to creators who want a low-credit way to animate an approved photo, product frame, character portrait or storyboard. In GlobalGPT, plan the shot with an LLM, create or upload the starting image, generate motion and sound with Grok Imagine Video 1.5, then continue with other tools for variants or refinement; those surrounding steps are GlobalGPT workflows, not native model features.
Does Grok Imagine Video 1.5 Support NSFW Content?
No support claim is made for NSFW content. xAI's acceptable-use rules and GlobalGPT safety checks apply, and requests that violate policy may be rejected; looser content restrictions are not a feature or selling point.
