In Mixer AI both support multimodal references and native audio; Seedance 2.5 accepts more inputs and reaches 30 seconds, while MiniMax H3 reaches 15 seconds and up to 2K. [Try it on Mixer AI](https://mixerai.org/?dl=kb_minimax-h3-vs-seedance-2-5#/canvas) ## Key differences MiniMax H3 in Mixer AI: first/last frames, up to 9 images, 3 videos and 3 audio files, 4–15 seconds, 768p/2K. Seedance 2.5: up to 30 images, 10 videos and 10 audio files, up to 30 seconds, 480p/720p/1080p. In the direct A/B, Seedance 2.5 was more stable on realism, macro detail, emotion and action; H3 sometimes preserved consistency but more often showed grainy AI texture and warping. ## Specifications | Spec | MiniMax H3 | Seedance 2.5 | Generation modes | from text / from first and last frames / from references | from text / from first and last frames / from references / video editing | First frame | Yes | Yes | Last frame | Yes | Yes | Input photos | up to 9 | up to 30 | Input videos | up to 3 | up to 10 | Input audio files | up to 3 | up to 10 | Input video length | 2–15 s | 2–30 s | Input audio length | 2–15 s | 2–30 s | Output audio | Native | Can be enabled or disabled | Minimum duration | 4 s | 4 s | Maximum duration | 15 s | 30 s | Resolutions | 768p / 2K | 480p / 720p / 1080p | Aspect ratios | 9:16 / 16:9 / 1:1 / 4:3 / 3:4 / 21:9 | 9:16 / 16:9 / 1:1 / 21:9 / 4:3 / 3:4 / adaptive | Prompt limit | 7,000 characters | 30,000 characters | Price, 1 s (different quality) | ≈ 10.04 coins · 768p | ≈ 37.9 coins · 720p There is no shared resolution for a direct price comparison, so each price includes its setting and is not highlighted as cheaper. ## Realism, liquid physics and camera control - The first test used a snorricam-style penguin dive. The reviewer found H3's fur and water visibly over-sharpened and grainy; Seedance looked more realistic, although its camera and penguin also rotated abnormally on water entry. - The reviewer explicitly says H3 looked better than older MiniMax versions, but the synthetic texture was still obvious in this shot. ## Macro detail and object physics - In the sushi test, Seedance kept the chopping sequence and rice orientation consistent between shots. H3 warped less than expected, but the cucumber was crushed and the wrong part of the scallion was being cut. - Even where geometry held reasonably well, the reviewer again saw a slight grainy AI texture in H3, most clearly on the cucumber skin. ## Emotion and character consistency - Both models struggled on the opening wide shot. H3 showed more warping and an extra arm; Seedance looked softer but avoided that deformation. - The reviewer rated Seedance voice acting and facial expressions higher. He still judged character and location consistency acceptable in both models. ## Stylization and action - In the stylized bicycle scene, Seedance kept the animation and motion cleaner; H3 showed more warping, changed the bike direction and rendered the tears poorly. - In the action test, H3 produced one usable final close-up, but the reviewer found wider framing much less stable; Seedance held the sequence together more consistently. ## Mixer AI facts versus review observations Third-party credit and price numbers are not used here. Duration, resolution and reference limits come from the current Mixer AI configuration. Visual-quality statements remain observations from specific test prompts. - H3 reaches 2K but has a 15-second maximum. - Seedance 2.5 reaches 30 seconds and accepts substantially more image/video/audio references. - Even this direct A/B exposed weaknesses in both outputs, so a production scene should still be rerun with identical inputs. ## What we compare [ MiniMax H3 First/last frames, up to 9 images + 3 videos + 3 audio files, native audio, 4–15 seconds, up to 2K. ](https://mixerai.org/en/knowledge/video/minimax-h3/)[ Seedance 2.5 Up to 30 images + 10 videos + 10 audio files, native audio, up to 30 seconds, up to 1080p. ](https://mixerai.org/en/knowledge/video/seedance-2-5/) ## FAQ Is this a direct MiniMax H3 vs Seedance 2.5 test? Yes. The reviewer ran both models through the same test plan and compared the outputs side by side. Does MiniMax H3 have a resolution advantage in Mixer AI? The current KB lists H3 up to 2K and Seedance 2.5 up to 1080p. Seedance 2.5, however, supports twice the maximum duration and many more references. ## See also [Seedance 2.0 vs Seedance 2.5→](https://mixerai.org/en/knowledge/compare/seedance-2-vs-seedance-2-5/)[Kling 3.0 Turbo vs Seedance 2.5→](https://mixerai.org/en/knowledge/compare/kling-3-0-turbo-vs-seedance-2-5/)[Seedance 2.5 vs Wan 3.0→](https://mixerai.org/en/knowledge/compare/seedance-2-5-vs-wan-3-0/) [Try it on Mixer AI](https://mixerai.org/?dl=kb_minimax-h3-vs-seedance-2-5#/canvas)
