Grok Imagine 1.5: Cinematic AI Image-to-Video with Audio (2026)
TL;DR
TL;DR: Grok Imagine 1.5 is xAI's image-to-video model, now on Viralance. It animates a single still image into a cinematic clip with native audio, at 480p or 720p, in durations of 5, 6, or 10 seconds. It's image-to-video only — give it an image plus a prompt describing the motion, camera, and sound, and it generates the clip.
Grok Imagine 1.5 turns one still image into a cinematic, audio-enabled video — you provide the image and a prompt for the motion, and the model animates it. This guide covers what it does, its specs, and how to use it on Viralance.
What is Grok Imagine 1.5?
Grok Imagine 1.5 is xAI's newer image-to-video model. Unlike text-to-video models that build footage from scratch, Grok 1.5 starts from your image and animates it — adding motion, camera movement, atmosphere, and native audio based on your prompt. It's the upgrade to the original Grok Imagine, focused on cinematic image-to-video.

How to write a Grok 1.5 prompt
Because it starts from your image, describe what moves and the mood, not the scene (the image already provides that):
- Motion: "subject slowly turns and smiles", "camera pushes in"
- Atmosphere: "soft rain, neon reflections, moody"
- Sound direction: "ambient city hum", "gentle rain audio"
Example: "Slow cinematic push-in, soft rain on the window, neon reflections, moody ambient sound."
