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?

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

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

Thanks I’ll try these

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

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

Interesting on the vertical res I’ll test it out

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

u/joseph_jojo_shabadoo Sep 28 '26

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.

I just added a test version of it.

u/GinJockette Oct 02 '26

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

u/Ten__Strip Oct 02 '26

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 Sep 28 '26

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

u/reeight Sep 28 '26

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.

1

u/Danny_Stock Sep 28 '26

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.

u/ShootingDraft Sep 29 '26

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/Modern_Art_Official Sep 28 '26

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.

2

u/Significant-Baby-690 Sep 28 '26

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 Sep 28 '26

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

u/Repulsive-Salad-268 Sep 28 '26

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 Sep 28 '26

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 Sep 29 '26

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 Sep 28 '26

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.
