Grok Imagine Video v1.5 Reference-to-Video vs MiniMax H3 Max Image-to-Video
Grok Imagine Video 1.5 reference-to-video vs MiniMax H3 Max image-to-video — verified SHA-256 baseline vs 3:4 ratio clamping.
Every value below is read from the model catalog at generation time — price and which parameters each model exposes. 7 of the 11 spec rows differ between these two. “Not exposed” means the model has no API parameter for it — it does not mean the capability is absent. Audio is the clearest case: MiniMax H3 generates sound with the clip but offers no switch to control it, while some models expose one.

Output
What each one actually produces
These are the real sample clips from the catalog, with the prompt that generated each. Watch both before you decide — a spec table will not tell you whether the motion reads the way you need it to.
Sample · prompt: “Handheld UGC-style clip. The person from <IMAGE_0> looks at the camera and speaks warmly. Casual phone-camera framing, soft indoor light, short social clip.”

Which should I use for image-to-video?
Whichever exposes the parameter you need — the table above is the honest answer. If you are iterating, use the cheaper model until the motion is right, then re-render once. If you need a specific resolution path, check the resolution row: some tiers reach it natively and others via a super-resolution pass, which is not the same thing.
