AI Search tests Seedance 2.5 and MiniMax H3 with the same multimodal inputs. Seedance follows rough 3D fight choreography more reliably, keeps high-action scenes coherent and turns sketch animation into a polished result, while both models handle long, detailed prompts and storyboard-driven commercials well.
MiniMax H3 stands out on music-video generation. It follows uploaded music, synchronizes cuts to the beat, preserves characters and reproduces typographic references more effectively in the test. Both models produce credible ads and multilingual speech, but neither reliably handles difficult factual visuals such as a geometric proof or locating Peru on a world map.
The technical tradeoffs are substantial. Seedance can accept up to 50 reference files and produce or extend clips in 30-second increments, but the tested service limits output to 720p and costs roughly five to six dollars for a 10-second generation. MiniMax produces up to 15 seconds at 2K and costs roughly one to three dollars through the tested interface.
AI Search concludes that Seedance is the better choice for fast action, character consistency and transforming rough animation into production footage. MiniMax offers better value, higher resolution, API access and an open model path that can run on sufficiently capable consumer graphics hardware.
