MiniMax Video Model Goes Viral with Stunning User Tests

MiniMax H3’s release quickly became a focal point in the open-source video community. ComfyUI announced day-0 support and said its optimizations cut VRAM usage by 66%, making local inference possible on consumer GPUs including the RTX 3060. Early testers highlighted H3’s strengths in long-shot coherence, reference following, style transfer, and prompt efficiency, while speed reports showed that higher resolutions remain expensive even on top-end hardware.

Confirmed

• ComfyUI’s @crystalalpine said H3 supports text-to-video, image-to-video, and video editing, with output up to 2K and 15-second clips with stereo audio. ComfyUI also said it spent months optimizing the model stack and reduced VRAM needs by 66%.
• @comfyanonymous demonstrated H3 running in native ComfyUI and generated a 1080p, 25-second video on an RTX 3060, showing that the workflow can run on consumer hardware under optimized settings.
• Community tests covered multiple workflows. @Monkeylashes shared a 15-second sample with three hard cuts inside one generated sequence and said character identity, physics, and spoken dialogue stayed coherent. @Kandoo85 tested using storyboard frames as visual reference for one-shot generation. @smereces and @SexyPapi420 focused on reference-to-video behavior, with both praising how closely the model followed source material.
• Several demos highlighted generation quality in specific scenarios. @topamine2 recreated the “Will Smith eating spaghetti” meme; @Rrblack posted a highly recognizable recreation of a classic scene from The Office; @ShagaONhan tested turning anime footage into live-action style video; @ItsCopperites said H3 could produce high-quality 2D animation from very simple prompts.
• Local performance reports varied substantially. Examples shared in the cluster include: 167 seconds for a roughly 15-second 608x352 clip on an RTX 4070 by @scooglecops; image-to-video on an RTX 3080 12GB by @Hrmerder; about 130 seconds for 480p on an RTX 5070 Ti by @tricck3zz; 58 minutes for a 10-second 1920x1088 clip on an RTX 5090 by @koakoAI; and 1 hour 44 minutes for a 720p, 15-second clip on a DGX Spark by @Saren-WTAKO.

Why it matters

• The main shift is accessibility: an open video model with broad functionality is being pushed into local, consumer-grade workflows rather than staying limited to large servers.
• Just as important is capability breadth. Tests in this cluster suggest H3 is not only a text-to-video model, but also a strong contender for reference-driven generation, storyboard control, and style conversion.
• Quality comparisons are still subjective, but some users such as @Rrblack and @SexyPapi420 said H3 outperformed open alternatives they had used before. Even with that enthusiasm, runtime data from users also shows that high-resolution generation is still far from cheap or fast.
