MiniMax H3

GlennHasABeard reports running MiniMax H3 in ComfyUI on a 12GB RTX 3060 with int8 weights at 20 steps. Each 15-second clip takes about an hour, and his soup demo was upscaled to 4K with Topaz.

GlennHasABeard shares prompts that constrain a hidden cat’s movement in locked-camera clips using local MiniMax H3 in ComfyUI. Topaz upscales the footage to 4K, and one render reportedly takes 50–60 minutes.

GlennHasABeard says eight of 35 locally rendered MiniMax H3 clips needed rewrites, three flawed results were kept and one idea was abandoned. His workflow uses ComfyUI generation and Topaz upscaling.

GlennHasABeard uses constrained prompts and locked cameras for local MiniMax H3 clips in ComfyUI. He reports fixing a reversed paw print, while generation takes about an hour per 15-second clip before Topaz upscaling.

MengTo built landing pages with MiniMax M3.1 Flash, using images to set visual direction before coding. Shared references, reusable skills and screenshot reviews guided revisions.

PurzBeats demonstrates looping MiniMax H3 videos in Comfy Cloud using _pxlpshr’s node pack. Follow-up instructions cover 48 fps interpolation and a VRAM reservation setting intended to prevent memory errors on an RTX 4090.

GlennHasABeard reports that each 15-second MiniMax H3 clip takes about an hour to render in local ComfyUI. His tests require objects to appear from the first frame or limit each subject to one timed action, followed by Topaz upscaling.

GlennHasABeard published prompts for local MiniMax H3 tests in ComfyUI, including cat scenes and shadow transformations. The posts document character drift without a reference image, failed prompt interpretations and a Topaz upscaling step to 4K.

GlennHasABeard tested sequential motion and object interactions with MiniMax H3 in ComfyUI. The fixed-camera clips use Topaz upscaling, and one repeatedly opens a lid from the wrong end.

GlennHasABeard's local ComfyUI tests held four objects more reliably than six and failed to recognize a butter curler. Locked-camera clips also tested motion direction before Topaz upscaling to 4K.

A creator ran open-weight MiniMax H3 locally in ComfyUI for locked-camera fog, macro practical-effect, and typewriter clips. Topaz upscaling produced 4K outputs, but the tests retained visible generation mistakes.

Hasan used Agentik to create a fashion image, perfume photo and burger video for $0.90. The workflow connects 374 tools through MCP with price approvals and spending caps.

GlennHasABeard’s local MiniMax H3 tests replace a failed block-collapse prompt with sideways sliding and give growing lace a directional path. He reports roughly 50 minutes per clip in ComfyUI.

A creator’s local ComfyUI renders show MiniMax H3 introducing fire despite a negative instruction in a matchbox scene. Other tests use explicit exclusions, locked cameras and sound cues to constrain short animations.

Local 15-second renders test transformations, a widening spiral, and a locked-camera tape measure. The creator says revising the spiral prompt changed an earlier result that drew rings instead.

Creators used local ComfyUI renders of open-weight MiniMax H3 for constrained motion studies, including a growing paper forest, rain confined to a bowl, velvet movement, and a lemon squeeze. The outputs were upscaled after rendering.

Creators used MiniMax H3 in ComfyUI to direct ordered weather changes, object transformations, and material movement in local 15-second renders. The tests also used audio cues and locked cameras, and several results were upscaled to 4K.

Creators render open-weight MiniMax H3 locally in ComfyUI with timed prompts, then upscale 15-second shots to 4K in Topaz.

Ben Nash estimates that reskinning a two-hour film with MiniMax H3 Max could cost roughly $1,500 to $3,000 or more in a practical run. His clean 768p single-pass estimate is about $576 before retries and multiple generations.

Glenn Has A Beard found that MiniMax H3 Max can miss object orientation and delayed cause-and-effect. His tests lock the camera, specify a final state, and stage timing constraints one at a time.

Creators are using stills, simple Blender previs, and reference clips to steer composition, character appearance, materials, and camera framing in video models. The examples span Seedance 2.5, Hailuo, and MiniMax H3.

A MiniMax H3 workflow gallery reports a 15-second 768p render in 4:03 on an RTX 5090, while a ComfyUI implementation targets 24GB RTX 3090 Ti cards. Community tools centralize controls and preserve latent data for stitching longer runs.

Hailuo says a team adapted MiniMax H3 into a world model that controls characters and cameras. The team says it used 8K samples while training 0.199% of the parameters.

Magnific used its agent to plan scenes and prompts for a character-led romantic trailer. It assembled the MiniMax H3 clips in Premiere through its plugin.

Levelsio launched a stream where chat messages generate each connected video segment from the prior clip. It uses fal’s post-trained MiniMax H3 Max variant and blocks NSFW and copyright prompts.

Practitioners are using MiniMax H3 Max with start-end frames, image-to-video, and text-to-video inputs. Community guides also cover H3 reference-to-video nodes and motion-control timelines for character work.

Creators report that MiniMax H3 Max can produce a 15-second clip in under 15 seconds. They say stitching video and audio becomes the bottleneck; one Fal-agent workflow generated a 67-second H3 Max and Nano Banana Pro clip in two minutes.

Creators report using up to six image references and short clips in MiniMax H3 for reference-led scenes. One workflow used the setup to make a Lego-style sitcom sequence for a presentation.

Creator tests on Fal put MiniMax H3 Max 15-second 720p renders at roughly 16–17 seconds. A separate 480p test took 5.17 seconds and cost $0.7125.

Creators describe using storyboards or generated stills as first, last, and reference frames for MiniMax H3 shots. One demonstrated the approach with a timed racing sequence, then assembled the results in conventional editing tools.

A creator used MiniMax Design to analyze two meme references and plan an FPV-style transition between them. The agent produced an H3 prompt specifying opening and closing frames for one continuous move.

Hailuo says MiniMax Design uses agents to plan and execute video production around MiniMax H3. Creator examples show agents deriving camera movement and pacing from a reference image before writing an H3 prompt.

Reddit users reported MiniMax H3 running on RTX laptops after fp16 and Spectrum mods, with tests for reference video, audio, and 25-second outputs. Others warned that turbo LoRA and attention settings can hurt motion or speed.

Reddit tests show MiniMax H3 running locally on GPUs from RTX 3060 to 5090. A 3060 reportedly takes about an hour for 10 seconds, while a 5090 makes 15 seconds in 84 seconds, with users also reporting motion and reference-video failures.

Hailuo said MiniMax H3 is now officially open-weight, with posts promoting local generation, text rendering, lip sync, and motion transfer. Creators tested it in ComfyUI, Krea, Magnific, and Mac workflows.

Creators testing Seedance 2.5 praised 30-second text-to-video, fewer hallucinations, and better motion control. They also flagged 720p softness and blur in heavy cartoon action, while shared workflows used references, storyboards, and CapCut edits to steer longer scenes.

ComfyUI added MiniMax H3 templates for text-to-video, image-to-video, reference-to-video, first-and-last-frame, and in-place editing. Early Reddit tests reported errors, weak defaults, 66s generation on an RTX 5090, and license questions.

Creators fed recorded dialogue, Seed Audio, and images into Hailuo H3 for lip sync, UI motion, outfit changes, and reverse-time shots. Hailuo is also pitching H3 for ads, UI/UX, and precise edits.

TopviewAI posts cite native 2K, 15-second generations, multimodal control, and claimed pricing at 30% of Seedance 2.0. Creators also tested H3 on ComfyUI Cloud, with ComfyUI support for open weights reported.

Hailuo H3 tests use recorded audio to guide lip sync, emotion, and dialogue without black-video workarounds. Other demos show stronger text-in-motion, preserved game HUDs, and reference-heavy ad shots.

Posts place MiniMax H3 in TopviewAI, Magnific, Hailuo, and Comfy workflows with native 2K, 15-second clips, lip sync, and multimodal references. Creators cite lower 2K pricing, while others note the weights were announced but not released.

Hailuo, Runway, Pika, and Magnific now offer MiniMax H3 or early access to creators. Tests cite multi-reference control, 15-second 2K/4K outputs, audio-aware motion, and some blur in action shots.

Creators are posting MiniMax H3 clips from Hailuo early access. They cite Omni Reference, native 2K with audio, 15-second clips, motion transfer, voice cloning, micro edits, and fast minimal-prompt runs.
