Happy HorsePhysically realistic AI video

Happy Horse is a physically-realistic video generation model on Nano Banana Lab, rendering 720P or 1080P clips from 3 to 15 seconds long. It is billed per second — 19 credits at 720P, 32 at 1080P — and works from a text prompt or a reference image whose aspect ratio the clip follows automatically.

Strengths

Grounded, believable motion

Physical realism

Weight, momentum, and material behaviour look right — liquids pour, fabric swings, and objects collide plausibly.

Flexible length

Anything from a 3-second loop to a 15-second scene in one render, with the price scaling per second.

Image-led framing

In Image to Video mode the clip inherits your reference picture's aspect ratio — no cropping surprises.
