Another quick Minimax H3 news and goodies round-up, for those who may have missed some items.

-> New in version 4.1.2 (19th August 2026) of the Fizgig trainer for LoRAs... "Minimax H3 now trains on video clips, on their sound, and on voice recordings alone: photos, clips and voice files in one folder to train one LoRA in one run". Fizgig can do so locally in 16Gb VRAM, without slowdowns. Adds a fix so the LoRAs will work correctly on both the 4-step Turbo or the official workflow, and has also benefitted from a major security audit. Fellow-Brit and industry professional Shoot The Sound has a good 20-minute tutorial today on YouTube, using the latest Fizgig and its dataset prep tool, to train a character+voice LoRA.

-> ComfyUI-MiniMaxH3-SingleFrame. Two still-image generation nodes, with the second being especially interesting. Given the usual first/last frames, it attempts to interpolate/generate a plausible single 'middle frame'. Has workflows, and requires no ComfyUI Core patching or special VAE.

-> A new H3 Prompt Journal. Some scenes require complex physical logic from the camera. The Journal's first three entries demonstrate how to write prompts for such scenes: for a 'Three-Person Occlusion-Linked Orbital Long Take' (e.g. elegantly redirect the camera between three moving people, in a single take); 'Dual-subject-speed-contrast' (e.g. a dancing master leads in a waltz, while his hesitant student follows his moves); and 'Single-subject-three-pose' (e.g. input three poses for one character, then have a gnat-sized camera... "sweep past feet, legs, torso, shoulders, hair - constantly redirecting around the moving [giant] body without ever slowing down").

https://github.com/LoveRain1997/h3-prompt-journal

-> 'Video -> H3 Prompt'. An "end-to-end pipeline that turns a video file into a ready-to-paste MiniMax H3 generation prompt". Appears to be a 'skill' for use with a local installation of OpenAI's Codex, which is a lightweight coding agent.

-> For MiniMax Music, a new rvq-encoder-169m-v4.onnx (676Mb), an... "encoder that turns audio into the codes Minimax generates, so a finished track can be handed back" to Minimax Music for further work. With this Minimax Music can continue a track. Or the user can replace a section, or even re-generate the same song but with a different performance. The ONNX format is very portable, and I guess it's only a matter of time before a ComfyUI workflow appears.

-> And finally, a detailed benchmarking of "the official reference-to-video workflow" on an RTX 3060 12Gb. Most low-VRAM users will of course be running smaller Minimax models in a 3060-optimised workflow. But... there's still important advice here for those considering buying a second 3060. They say... "Two cards are still not one big card. Two RTX 3060s do not present 24GB to a workflow, and our attempt to at least run two jobs in parallel was blocked by system memory rather than VRAM."

Another quick Minimax H3 news and goodies round-up, for those who may have missed some items.

-> New to me are the 'ComfyUI H3 Motion Context — MultiRef & Latent Masking' custom nodes for ComfyUI. (Hat-tip: I learned about it via the charming fellow-Brit Nerdy Rodent on YouTube). Lets you add keyframes at any point, not just first/last. Can also seamlessly extend an existing video, while taking measures to... "reduce RAM and cache pressure during long-form final output". Has workflows. Updated yesterday, with new features including the claimed ability to chain... "a sequence of H3 video clips around a single song".

https://github.com/seitanism/ComfyUI-H3-Motion-Context-MultiRef

-> Minimax Music has a new set of concept slider LoRAs. Including 'breathy vocals', and a 'live performance to a crowd'. With ComfyUI workflows.

https://huggingface.co/ntc-ai/minimax-music3-concept-sliders

-> New ComfyUI-CGlide custom nodes for Minimax in ComfyUI. Including 'Glide Preview', a motion-preview node that lets you assess your video as it generates. Only at seven frames per second, but it may give you the confidence to cancel the generation if things seem awry.

https://github.com/CGlide/ComfyUI-CGlide

-> ComfyUI-H3-Context-Noise. This tapers off the colour in the tail-frames of the previous shot, thus preventing colour residue from spoiling the seams between your shots. If you notice this problem, give it a shot.

https://github.com/beijinren/ComfyUI-H3-Context-Noise/blob/main/README.en.md (English version of the ReadMe)

-> A new archive of Minimax H3 style LoRAs. The most interesting being an comic-book style in the AstroWitch - Cinematic Comic Style - MinimaxH3 - ASTROWITCHV01H3.safetensors file, with ASTROWITCHV01H3 as the trigger-word. The first non-Japanese comic-book style LoRA I've seen, and it has a pleasing sort of US/UK 2010s 'amateur indie comic' look.

https://huggingface.co/EllaPriest45/MinimaxH3_Styles/tree/main

-> A Reddit post reporting apparent success with motion-transfer, by using a Minimax reference video converted to a DensePose sequence. This makes me wonder how Minimax would react to a greyscaled clown-pass render from a 3D figure animation, which would look similar... and might also solve the problem of DensePose not doing hands?

https://blender.stackexchange.com/questions/102672/how-to-create-a-clown-pass-for-material-selection-in-photoshop ('what is a clown-pass?' visual example)

-> Yes, I'm aware of the new non-commercial ComfyUI MiniMax-H3 SPEED Sampler. But I see it requires his "MiniMax-H3 plugin"... which is "404 not found" on the link to it, and which doesn't exist on his repository (I poked around).

-> And finally, a new big curated listing of all known Minimax H3 items. Includes a long list of the various Turbo LoRAs which have been produced to date.

Another quick Minimax news and goodies round-up, for those who may have missed some items.

-> MiniMax-H3-Longvideos, a new custom-nodes pack for ComfyUI. Extend the output from a simple Minimax prompt... "One prompt in. A ~2-minute MiniMax-H3 video with audio out." It's said to attempt to solve many of the problems arising from chaining prompts/shots. No workflow, but it has connection instructions.

https://huggingface.co/Smite79/MiniMax-H3-Longvideos

-> ComfyUI_MiniMax_H3_Extender. More complex than the Longvideos node above, this node set... "chains multiple video clips with motion context, disk caching, dynamic image references, audio reference support, and seamless final video/audio decoding." Also has matching workflows.

https://github.com/tritant/ComfyUI_MiniMax_H3_Extender

-> ComfyUI-Fantastic-MiniMaxH3-PromptBuilder custom nodes. Helps you build prompts locally inside ComfyUI, while adhering to the built-in official prompt guide... "H3 doesn't want a casual sentence — it wants a structured prompt with named sections, shot timings, speaker IDs, and tags pointing at your reference media." No LLM required. Convoluted workflows, but for simplest use: just plug it into your existing prompt node, then click on the blue box to open the Builder. Then build the prompt, and pass it back to the prompt box.

-> Last updated a month ago, ComfyUI-FirstframeLastframeExtractor will help in more or less reproducing a draft H3 fl2va video at a larger size after locking the seed/prompt. Works as advertised, very simple. Plug it into the VAE decode node, it auto saves the two frames you need. Then you optionally load these images back to your first-frame/last-frame inputs, via the native "Load Image (from outputs)" nodes.

https://github.com/RmaNMetaverse/ComfyUI-FirstframeLastframeExtractor

-> A current RTX 3060 12Gb workflow for text-to-video Minimax. Tested to 2.0 megapixels without failing (24Gb system RAM, older server + 3060 card). With Kitchen Attention, 3060 12Gb optimisations, a prompt helper, and first and last frame auto-extraction as well as input.

https://jurn.link/dazposer/index.php/2026/08/15/updated-my-minimax-workflow-for-the-3060-12gb-card/

-> A prompt to neatly mix styles in one video. e.g. SpongeBob SquarePants as a cartoon, appearing in a live-action sitcom.

https://www.reddit.com/r/StableDiffusion/comments/1vp8dpc/mix_style_inside_the_same_scene_minimax_h3/

-> And finally, there's now a low-VRAM friendly text-encoder for use with Minimax Music GGUF. The smaller/pruned GGUF file is minimax_music3_text_encoder_pruned_Q6_K.gguf (6.8Gb). Maybe your fave band/sub-genre was pruned out, but... maybe not? Test it and see. Note also ComfyUI's Music prompting guide, and Minimax's official Music demos page.

https://huggingface.co/ivanfromm/MiniMax-H3-Prompt-Rewriter-LoRA-GGUF/tree/main

-> Anime Video Line Art Colorization node, which requires DiffSynth-Studio. Input a line-art video, have it beautifully auto-coloured and with temporal consistency. Convincing examples. No idea how well it will work with non-anime animation line-art.
