Related category score

Seedance 2.0 Fast leads here by 2.2 points.

Show the full prompt

Conceptual still-life commercial shot, locked medium frame on a translucent plastic shopping bag bulging with white daisies and baby's breath, set on a flat warm-taupe seamless. Across the wrinkled surface of the bag, the words "Megaton Reviews" are printed in confident red block letters that distort gently as the bag breathes in a light draft. Crisp studio key light, every letter holding shape and curvature through plastic creases, the playful collision of high fashion and corner-store packaging.

Show the full prompt

Stylized art-direction motion piece, locked frontal medium shot on a classical marble bust set against a saturated cinnabar-red backdrop, a crown of glowing orange silk ribbons and tiny sparks swirling above its hair. The stone remains undamaged beneath the kinetic light. Hard side key light carving each curl in shadow, gentle smoke-like haze rising past the frame, theatrical illumination.

Show the full prompt

Extreme wide-angle 16mm-style fisheye, locked-off on the bow of a tall ship as an adult sailor crouches near the camera, the bowsprit and rigging curving around him in distorted arcs, gray Atlantic swell heaving behind. Wind whips his curls, ropes thump against masts. Heavy practical grain, vignetted edges, desaturated blues and bone whites, archival expedition film texture.

Methodology

How we tested Seedance 2.0 Fast and HappyHorse-1.0

We score two things separately: how good the video looks to a reviewer, and how reliably the file itself holds up. A model can make great-looking footage and still deliver clips with freezes, bad framing, or unstable motion.

Reviewer scores
Both models receive the same prompts. Professional reviewers score how well each video follows the prompt and handles motion, composition, people, objects, animals, animation, and on-screen text. Scores use a 0-100 scale.
File reliability
Automated checks review 235 clips for freezes, bad framing, compression problems, unstable motion, distorted geometry, exposure problems, and invalid file properties.
Missing scores
Categories with a score for only one model are shown but excluded from the head-to-head win count. Price and generation speed stay separate because they use different units.
Last updated
Reviewer scores and rankings use results from July 22, 2026. Reliability results use the latest completed test for each model. Provider prices and rankings can change.
