Seedance 2.5 vs Wan 3.0 vs H3

Seedance 2.5, Wan 3.0, and MiniMax H3 are the late-summer 30-second conversation. They are not interchangeable. Seedance owns locked references. Wan owns document order and multimodal stacks. H3 owns the hosted dialogue-and-motion athlete lane. Pick by the brief.

The Veo/Kling routing post is Seedance 2.5 vs Veo 3.1 vs Kling 3 by job. This page adds Wan and H3 to the router for creators who heard “30 seconds” and stopped reading.

Three jobs

Identity and brand lock. Product stills, wardrobe, face, pack shot that must survive motion. Seedance 2.5 is built for image-to-video and reference stacks — including long multimodal reference budgets in the 2.5 generation. If the brief is “this SKU cannot drift,” start here.

Artifact already exists as a file. PDF, deck, sheet, URL that already has narrative order. Wan 3.0’s document-to-video path is the reason to open Wan first. See Wan 3.0 document to video. Wan also competes on long single-pass storytelling; it does not automatically beat Seedance on a locked hero still.

Athlete take with speech energy. When the clip needs human physics, multilingual mouth energy, or a hosted H3/Hailuo-class generate that is not a reference stack, MiniMax H3 is the lane to evaluate next to Kling and Veo. Do not buy “open weights” marketing without reading MiniMax H3 open weights vs hosted 2K.

What “30 seconds” does not mean

A 30-second native pass is not a licence to skip editing. It means fewer stitches for a demo, a shelf talker, or a single-scene ad. It does not mean:

• Always-on 4K dialogue (still check Veo 3.1)
• Multi-shot comedy timing (still check Kling storyboard rows)
• Cheap infinite regenerations (length multiplies cost — cost per second with audio)

Arena Elo on an 8-second beauty clip will reshuffle weekly. Your brief will not.
