MiniMax H3 Anime Video Generator: 15 Seconds, 4:3, and the Title Card Veo 3.1 Botched

A hands-on comparison of MiniMax H3 and Google Veo 3.1 for anime-style video generation argues that workflow constraints such as duration, aspect ratio, audio defaults, reference capacity, and instruction-following can matter as much as visual quality. Using identical anime keyframes and prompts, the test found that both models produced appealing imagery, while H3 better maintained character continuity, flat cel-shaded styling, Japanese title text, generated audio, and a requested whip-pan transition in the sampled run. H3 supports 4–15 second clips, six aspect ratios including 4:3 and 21:9, native audio with Japanese dialogue support, and larger mixed-media reference packs, whereas Veo is limited to 4, 6, or 8 seconds, 16:9 or 9:16 output, and up to three image references. Veo retains seed control and negative prompts, which can help reproducibility and reduce unwanted 3D or photorealistic drift, but its API requires audio and higher resolution to be enabled manually. The comparison also notes that H3 is generally less expensive but slower in the reported tests, offers downloadable weights with regional licensing restrictions, and should be evaluated through repeated runs rather than a single example.
