Supir and Hidiffusion would be good methods to add into your tests now! Thanks for posting this.

Hi Han, thanks for making this video. It's a really good explanation and walkthrough on upscaling. I've been experimenting with upscaling, and have watched a number of videos. Yours is the most coherent and straightforward explainer I've seen. Thanks again, and all the best for your channel!

Is there an imgae2upscale workflow?
I want to convert stock images to a higher resolution.

What do you do exactly on 1:59 to get that Normal Upscale window? It seems you just drag, but it can't be. I have been stuck for hours. Did you press any keys, could you break it down? Thanks!

Dude, I have installed whatever you said and restarted. But still I don't get anything to select for control net
Do I have to install some model?

Why My Comfyui got this error when running your workflow, could you please guide me to fix it? I will appreciate that! "Error occurred when executing UltimateSDUpscale:

mat1 and mat2 shapes cannot be multiplied (154x2048 and 768x320)"

Is there a reason to use lineart instead of the tile controlnet?

Could you make an upscale method that works best on lower end GPU? I'm on 4GB so I can't do 50 steps for upscales. Need something a bit lower if possible.

Brother literally thanks a lot❤ Your indepth explanation is soo awesome. Pls make one video of how to make Ai model like Aitana Lopen in 4 Gb Vram device. Also pls share your discord.
Thanks man❤

Hi Han, thanks for the totorial. im in Singapore as well .lets meet for a drink or two if you are keen.

[magimyster]

maybe for the last image (HiresFix) that didn't look identical ... I think you should have lowered the denoise 😊

[SoniInterio]

Can i upscale video like this same workflow please reply?

[rluzentales]

Hello, please update your links in the comments.

[kishirisu]

Use tiled upscale if you not stuck in 2022

[Cyrecok]

i prefer hiresfix + controlnet tile + big denoise for realistic, sdultimate for others
