MiniMax Open-Sources H3 Video Model with 2K Native Generation

MiniMax has open-sourced its native 2K video generation model H3 (possibly codenamed H3 ref2va), which quickly sparked a wave of community tests due to its high generation quality and coherence. Current findings show the model can generate long videos, handle complex physical interactions, and run smoothly on local hardware, marking it as a strong contender in the multimodal video generation arena.

Confirmed

• Core performance and open source: The model supports native 2K resolution generation with excellent detail and coherence. Developer ostrisai generated 1,000 videos covering a wide range of topics and released the 1.5-hour results as an open-source dataset.
• Local deployment and long videos: User singularitynotnow confirmed local generation of a 30-second unedited video at 1024x576 resolution in 6 minutes 46 seconds, using 288GB VRAM with NVIDIA Sol-Attn acceleration. The Pixio team also confirmed breaking the 15-second limit with fast generation and good prompt coherence.
• Multi-scenario creation: FDosha showcased realistic gravity manipulation; lazyspock used a long prompt to generate South Park-style 2D animation; Co-OB created a Dexter vs. Thanos animation; umeshai demonstrated macro creativity; Candiru666 showed cosmic color and light.
• Workflow compatibility: jdude found H3 can seamlessly continue non-H3 generated clips, enabling mixed-model workflows. TheruleofThetra stitched three clips and used RIFE to interpolate to 96 FPS for a high-frame-rate effect.

Why it matters

• On-device and open ecosystem: The high-quality open weights allow local running (e.g., Co-OB on RTX 3080), lowering the barrier for high-quality AI video creation and empowering independent creators and the open-source community.
• Multimodal competitiveness: Breakthroughs in long video generation, complex prompt understanding, and multi-style rendering prove its top-tier capability in the competitive multimodal video track, offering new productivity tools for film, animation, and meme creation.
