Grok Imagine Video 1.5 — AI video generator

1080p image-to-video from xAI.

Grok Imagine Video 1.5 is the HD tier of xAI's video line and the only model on comfyarts that delivers 1080p. It works from an image: you supply the opening frame and it animates outward from there, which keeps composition under your control in a way text-to-video does not.

It keeps the wide ratio list of the standard tier, so a 1080p clip can be 4:3 or 3:2 rather than only widescreen or vertical. For anything with a delivery spec attached — a client, a broadcast slot, a paid placement — this is the model that meets it.
