The table below is built from current product controls, while the visual section shows what to inspect with the same inputs and prompt instead of inventing one universal winner.

MiniMax H3: Build a scene from separate references for appearance, movement and sound. Start with the specification table: it reflects current modes, input media, duration, resolution, aspect ratios and a normalized price where a fair comparison is possible. ## Specifications | Spec | Seedance 1.5 Pro | MiniMax H3 | Generation modes | from text / from first and last frames | from text / from first and last frames / from references | First frame | Yes | Yes | Last frame | Yes | Yes | Input photos | No | up to 9 | Input videos | No | up to 3 | Input audio files | No | up to 3 | Input video length | No | 2–15 s | Input audio length | No | 2–15 s | Output audio | Can be enabled or disabled | Native | Minimum duration | 4 s | 4 s | Maximum duration | 12 s | 15 s | Resolutions | 480p / 720p / 1080p | 768p / 2K | Aspect ratios | 9:16 / 16:9 / 1:1 / 21:9 / 4:3 / 3:4 | 9:16 / 16:9 / 1:1 / 4:3 / 3:4 / 21:9 | Prompt limit | 2,500 characters | 7,000 characters | Price (different settings) | 11 coins · 4 s · 720p | 43 coins · 4 s · 768p There is no shared resolution for a direct price comparison, so each price includes its setting and is not highlighted as cheaper. ## What to compare visually For a fair A/B test, use the same scene and, where both modes allow it, the same first frame. Inspect motion continuity, character and object consistency, physics and contacts, camera behavior, temporal deformation, in-clip cuts and audio synchronization. ## What to inspect with Seedance 1.5 Pro Animate a portrait, show a product or connect two frames in a short scene with sound. - Text mode needs no files. Image mode takes a starting frame and an optional ending frame. - Mixer AI offers 4, 8 or 12 seconds at 480p, 720p or 1080p. - Two images are the limit; this model page does not use separate video or audio references. - Incompatible poses or different objects at either end can produce morphing rather than believable movement. ## What to inspect with MiniMax H3 Build a scene from separate references for appearance, movement and sound. - Text mode, one or two frames, or references. - Up to 9 images, 3 videos and 3 audio files. Video and audio each have a separate 15-second total limit; audio needs a visual reference. - The first five images are included in the base calculation; additional images increase the price. - Input video adds billable duration. Check the total, not only the resolution. ## How to run a fair comparison - Lock one prompt, aspect ratio and a duration or resolution that both models actually support. - If input modes differ, compare the shared workflow first and test each model's extra controls separately. - Run more than one attempt: a single output reflects one seed, not the model's overall consistency. - Score prompt adherence, visual artifacts, reference preservation and the cost of the setting you would really use separately. ## What we compare [ Seedance 1.5 Pro Animate a portrait, show a product or connect two frames in a short scene with sound. ](https://mixerai.org/en/knowledge/video/seedance-1-5-pro/)[ MiniMax H3 Build a scene from separate references for appearance, movement and sound. ](https://mixerai.org/en/knowledge/video/minimax-h3/) ## FAQ How should I compare Seedance 1.5 Pro and MiniMax H3 fairly? Use a workflow both models share, keep inputs and prompt identical, then run several generations. Compare prompt adherence, visual consistency and the price of the setting you need as separate dimensions. Are both models available in Mixer AI? Yes. This page is generated only for models in the current public Mixer AI catalog; if a model leaves the catalog, the automated comparison must stop passing validation. Which model is better? There is no universal answer. First eliminate a model that cannot accept the input, duration, resolution or format you need, then compare outputs on your own scene. The table highlights only measurable advantages in individual specifications. ## See also [MiniMax H3 vs Seedance 2.5: model comparison→](https://mixerai.org/en/knowledge/compare/minimax-h3-vs-seedance-2-5/)[Veo 3.1 vs Seedance 1.5 Pro: technical and visual comparison→](https://mixerai.org/en/knowledge/compare/veo-3-1-vs-seedance-1-5-pro/)[Veo 3.1 vs MiniMax H3: technical and visual comparison→](https://mixerai.org/en/knowledge/compare/veo-3-1-vs-minimax-h3/)[Kling 3.0 vs Seedance 1.5 Pro: technical and visual comparison→](https://mixerai.org/en/knowledge/compare/kling-3-0-vs-seedance-1-5-pro/) [Try it on Mixer AI](https://mixerai.org/?dl=kb_seedance-1-5-pro-vs-minimax-h3#/canvas)
