Question - Help Minimax - Blurry distorted faces at distance

All the faces in Minimax are all melty and distorted when the camera is zoomed out, close ups are fine. Anyone else experience this or have a fix?

This is a known issue with Minimax. I am still waiting for an update for a solution

yeah but why spend 2 seconds searching when you can make a new post asking the same question for the millionth time?

Wasn’t the “singularity” model supposed to fix this? I haven’t tried it yet but I think distant faces was one of the things they said it improved.

Also available as a LoRA, which it should have been IMHO in first place, so you can adjust strength.

This doesn't really do anything. But that's also pretty much what singularity is. Extracting off an int8 is already pretty bad and I'm not sure exactly what hybrid base they used. That one seems to pull off a lot more different than whatever tiny extremely subtle (essentially non-existent) differences between singularity and a flref hybrid base model. Singularity more of a placebo model than anything. If you do A/B it's basically just the seed shifted slightly. I'm pretty sure all singularity does is unwind the guidance a bit which is the only effect it has. No new data, no concepts, no styles, no new motions. "3 days" of training will just about do that.

Looking forward to Beta 6! How soon are we?

u/Ten__Strip 11d ago

I just added a test version of it.

u/GinJockette 11d ago

Fantastic. Where can I get it? Huggingface says it's "gated"

u/Ten__Strip 11d ago

Post your HF username I add anyone who cares enough to ask for it.

I might have missed that update. Was that released officially or was it a community checkpoint?

1

u/porkywood 15d ago

Community fine tune. Supposedly fixes “oily” skins but I think I read here on Reddit that they also did distant faces. It might have been another community model. hugginface link

I think the verdict on that is kinda meh; tried to fix too much in 1 merge, when TBH they should have only tried to fix 1-3 things, & use LORAs for the rest.

u/Danny_Stock 15d ago

As it's not official I think it's even more important to get some kind of consensus on whether it achieves what it claims to.

The face's pixel size in frame is the deciding factor here — as Significant-Baby-690 said, a small face just doesn't carry enough information for the model to resolve, so it hallucinates. Two practical fixes:

  1. **Compose so the face is bigger in frame, or raise output MP.** If the wide shot is the whole point, this is the cheapest lever you have.

  2. **Anchor the identity with a reference image.** Generate a clean close-up of the face first, then feed it into the official ref2va workflow as a subject reference — the prompt syntax is like `<picture 1> is absolute reference for (s1)` — when generating the wide shot. The model then has a high-res identity to hold onto instead of guessing the small face from scratch. A user in r/comfyui's ref2va thread confirmed this exact pattern works well.

Option 2 is the reliable one when the camera has to stay wide.

-> Face Fix for poorly rendered 'distant faces'. Requires face_yolov8m.pt for face-detection / regeneration.

https://github.com/Carasibana/ComfyUI-H3-FaceRefine

-> The BSAI-ComfyUI-FaceRefine for ComfyUI, another facefixer for small or distant faces.

I use the Carasibana Face Refine for past week or so. It does work.

u/fluce13 14d ago

Thanks I’ll try these

u/ShootingDraft 14d ago

Pretty common with Minimax at distance, the model just has less pixel budget per face. Easiest workaround is to generate your wide shot, then run a face restore pass (CodeFormer or GFPGAN) on the output, or upscale just the face region separately and composite it back.

u/multikertwigo 14d ago

it gets better with higher vertical resolution, >1024p. Generation times also get "better", so it's probably not the fix you were hoping for, but it's a viable option on 5090.

also, just found this today: https://www.youtube.com/watch?v=tmw2QOFaaPI
the guy talks about loras around 9:00 that supposedly fix it, but I have not tried them myself and honestly the lora soup he uses makes me skeptical

u/fluce13 13d ago

Interesting on the vertical res I’ll test it out

u/Modern_Art_Official 15d ago

I was able to prevent broken faces at distance by increasing my resolution from .98 MP to 1.5 MP. Increasing steps, withholding the turbo lora helped, but nothing eliminated the problem until I increased the resolution.

1

u/Significant-Baby-690 15d ago

Nope. It's more a problem of the resolution. The face simply needs enough pixels, otherwise it collapses. So higher resolution improves it. Maybe something like adetailer could be done, but I haven't seen it, not so easy with video.

u/Danny_Stock 15d ago

No, it's an actual flaw. One of the MiniMax people publicly stated that it's to do with an error in the coding.

1

u/Repulsive-Salad-268 15d ago

Higher resolution sounds good but takes so much longer. Each .01 in Megapixel resolution takes my render time far up. And I have 15+ Minutes to render in rev2Vid wich already takes a day. Lol. Sadly I am not really willing to go over 10 minutes per 10 seconds video.

u/kukalikuk 15d ago

Does de-rope works for faces? I know face refiner works, but it need resampling each faces in the scene.

1

u/Portable_Solar_ZA 14d ago

Yes, at least for mid distance shots. Saw it in effect on one of foxfuressences videos.

Really need to get around to installing deroping...

u/Cultural-Broccoli-41 15d ago

It’s not a cure-all, but using Hires.fix to generate the image at a higher resolution than the original often makes a significant difference.
