Make High-Res Flux.1 Images with Fewer Stripes in Seconds with ComfyUI!

Flux.1 is great, but those boxes or horizontal / vertical lines are almost impossible to unsee once you see them. This simple method of both generating and upscaling images should help to reduce those annoying stripes, and it's been giving me good results so far. Using multiple samplers also nets you some great details, along with the use of scaled uniform noise, for amazing results in just 8 steps!
Who needs to wait three times longer for 24 steps? Not you 😉

9:11 "Is that an upscale?" has the same energy as "Are you not entertained?" in The Gladiator.

I didn't know that upscale controlnet was supported yet! Awesome. :-) The way it should work normally is using tiled upscale on an img2img with low(ish) denoise. I will try dpmpp_2m tomorrow to see if it solves the banding. Thank you so much for the video! 🥰

So far I've simply used an SDXL final stage to get rid of the stripes. If you upscale by factor 2 with a denoise of 0.25 and then downscale in pixelspace with Lanzos or bilinear the stripes are gone and even at max zoom, the differences to the original Flux output are barely noticeable because the intermediate resolution was too high for destroying anything at this low denoising. Of course you can change this and that but for the most original Flux output, I found this to be the best option.

Those overlay lines were driving me crazy too, especially in custom trained Loras. Thank you for this

I see you are using dualcliptextencode, is there any practical benefit to writing two separate prompts compared to a regular cliptextencode node?

[wakegary]

im scared to watch this because i dont know what these lines are. are kids snorting them?

[zerint]

Watched this hoping to find out more about the layer nerdy details of the big one - 1. found you unexpectedly using my CLIP and 2. learned something else entirely instead. 😂 TY! 👍
But... Any clue what exactly causes these stripes in the first place? I mean, with my crazy node of layer shuffle you already found, it's totally possible to amplify those stripes. The "attn" gets you pixel art (well, *patch* art, to be precise) - and messing with the Feed-Forward Layers, you can even have images made of pure stripes and color, where the stripes are the main attraction!
But would it also be possible to reduce them, by directly messing with the big transformer? 🤔

[DJTripleRRR]

So weird, I haven't had any issues at all...

Is this just specifically the pure Flux Schnell/Dev?

[generalawareness]

where can I get the force to cpu from?

[Dan-qnng]

I found if I used the 2mp resolutions I got the stripes especially with LoRAs. If I use SDXL resolutions, all stripes disappear with LoRAs…but then it’s only 1mp unfortunately

[fredmcveigh]

I use forge and swarm for Flux and I don't get these problems. Perhaps it's Comfy that is at fault.

[KarlitoLatent]

yeah, thats why I dont use flux for upscaling, I got horizontal stripes and could not get rid of them no matter what I do 🙃

[captainpike]

These days, it's irrelevant to keep workflows only for Patreon members. Someone confident enough with Comfy will watch and build a similar workflow and put it on the cloud. I've already seen three different channels with similar workflows. Keeping workflows exclusive to paid platforms can limit innovation and creativity. Knowledge grows when you share

whait what? gguf are slower? me running gguf on a 3090 doing a big facepalm
