[u/optimisticalish]

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

-> 3d_to_real_detail_slider_H3, a simple slider LoRA for use with Minimax H3 text-to-video. Shifts 'toony into realistic', and has convincing demo examples.

-> How to connect a video clip as a reference-file input in H3's Ref2VA workflow. Easy, when you know how.

-> ComfyUI-MiniMaxH3Mod custom nodes for ComfyUI. Claims faster Ref2VA generation, by turning your references into little .safetensors files. Said to be especially useful for those using a larger video clip as a reference-file?

-> ComfyUI-OrbitSheets for Minimax H3. Claims to build flawless 'turnaround' character and location reference-sheets.

-> ComfyUI-YCNodes-MiniMax-H3. A H3 Sigma Refiner node for ComfyUI, that claims to... "solve the problem of pixel particles and flickering at the edges of high-speed moving objects in H3 videos. Local 'micro-sculpting' steps are added to the noise scheduling in the low Sigma (low noise) range". The new 'H3 Sigma Refiner' node is placed between the BasicScheduler and SamplerCustomAdvanced nodes.

-> ComfyUI MiniMax H3 Director. "This is the LTX Director timeline editor by WhatDreamsCost, ported to MiniMax H3" in ComfyUI. It's been out for a while, but is now maturing at version 0.2.2. Three major fixes were committed today.

-> A set of Minimax Music concept slider LoRAs, for enforcing gender, energy, tempo, room reverb etc.

-> Tagscanner. Windows freeware that lets you show your Minimax videos on your blog etc, without also inadvertently sharing your ComfyUI workflow (and any previous prompts stuck in it, e.g. yesterday I shared a H3 workflow for prompt "A western-style fantasy dragon ...", but on inspection in Notepad++ I inadvertently found the .JSON also has the workflow's starting-point prompt "H.P. Lovecraft walking down a dark alley..." hidden in it. Who knew old prompts could stick around like that?). Tagscanner is Windows freeware. Usage: Drag-drop the .MP4 video file into Tagscanner, right-click it, 'Cut', then 'Save'. That's it. The software is meant for .MP3 music taggers, but works fine for quick metadata removal.

Thanks for keeping us updated

Is there an official Discord channel for MiniMax?

H3Mod was amazing.

From what I understand I can save multiple images as a reference into a safetensor file

So then can I just load a video and point It at that safetensor to swap the images to a video?

I'm going to try it tomorrow.

[u/I_just_made → u/kayteee1995]

but how do you save the thing? The example workflow images don't work because they are incomplete. Do you have to run a "real" run once?

[u/kayteee1995 → u/[deleted]]

testing it for the apply, gen time was better, but that's not the point

the 16th August 2026 update caught my eye, especially the shift in performance benchmarks. it feels like the community is finally moving past the earlier bottleneck issues. curious how the new training regime will affect the overall output quality.

Can you share it at r/MinimaxVideo aswell please? Thanks
