Comfyui upscale image reddit

Comfyui upscale image reddit. . Working on larger latents, the challenge is to keep the model somehow still generating an image that is relatively coherent with the original low resolution image. Welcome to the unofficial ComfyUI subreddit. upscale image - these can be used to downscale by setting either a direct resolution or going under 1 on the 'upscale image by' node. I gave up on latent upscale. We introduced a Freedom parameter that will drive how much new detail will be introduced in the upscaled image. Latent upscale it or use a model upscale then vae encode it again and then run it through the second sampler. Depending on the noise and strength it end up treating each square as an individual image. There's "latent upscale by", but I don't want to upscale the latent image. natural or MJ) images. "LoadImage / Load Image" "Upscale Model Loader / Load Upscale Model" "ImageUpscaleWithModel / Upscale Image (using Model)" "Image Save / Image Save" or "SaveImage / Save Image" That will upscale with no latent invention/injection of creative bits, but still intelligently adds pixels per ESRGAN upscaler models. Upscale to 2x and 4x in multi-steps, both with and without sampler (all images are saved) Multiple LORAs can be added and easily turned on/off (currently configured for up to three LORAs, but it can easily add more) Details and bad-hands LORAs loaded I use it with dreamshaperXL mostly and works like a charm. Is there benefit to upscaling the latent instead? Some images made with my next model, Aether Real SDXL. It fixes issues with bad skin on the base model. this is just a simple node build off what's given and some of the newer nodes that have come out. There’s only so much you can do with an SD1. And I'm sometimes too busy scrutinizing the city, landscape, object, vehicle or creature in which I'm trying to encourage insane detail to see what hallucinations it has manifested in the sky. With it, I either can't get rid of visible seams, or the image is too constrained by low denoise and so lacks detail. Please keep posted images SFW. This. I've so far achieved this with the Ultimate SD image upscale and using the 4x-Ultramix_restore upscale model. Nearest-exact is a crude image upscaling algorithm that, when combined with your low denoise strength and step count in the KSampler, means you are basically doing nothing to the image when you denoise it, leaving all the jagged pixels introduced from your initial upscale. (Optional) Upscale to 3x by Default and using ControlNet to stick to base image, speed provided by Automatic CFG. 0 Alpha + SD XL Refiner 1. second pic. I think I have a reasonable workflow, that allows you to test your prompts and settings and then "flip a switch", put in the image numbers you want to upscale and rerun the workflow. Latent quality is better but the final image deviates significantly from the initial generation. Where a 2x upscale at 30 steps took me ~2 minutes, a 4x upscale took 15, and this is with tiling, so my VRAM usage was moderate in all cases. 5 and I was able to get some decent images by running my prompt through a sampler to get a decent form, then refining while doing an iterative upscale for 4-6 iterations with a low noise and bilinear model, negating the need for an advanced sampler to refine the image. Edit: Also I woudn't recommend doing a 4x Upscale using a 4x Upscaler (such as 4x Siax). py, in order to allow the the 'preview image' node to At the moment i generate my image with detail lora at 512 or 786 to avoid weird generations I then latent upscale them by 2 with nearest and run them with 0. My problem is that my generation produce a 1 pixel line at the right/bottom of the image which is weird/white. 5 ~ x2 - no need for model, can be a cheap latent upscale Sample again, denoise=0. it's nothing spectacular but gives good consistent results without This is the image I created using ComfyUI, utilizing Dream ShaperXL 1.

It's high quality, and easy to control the amount of detail added, using control scale and restore cfg, but it slows down at higher scales faster than ultimate SD upscale does. go up by 4x then downscale to your desired resolution using image upscale. The final node is where comfyui take those images and turn it into a video. Thanks. This works best with Stable Cascade images, might still work with SDXL or SD1. It will replicate the image's workflow and seed. After that I send it through a face detailer and an ultimate sd upscale. The best method as said below is to upscale the image with a model ( then downscale if necessary to desirate size because most upscalers do X4 and it's often too big size to process) then send it back to VAE encode and sample it again. Please share your tips, tricks, and workflows for using this software to create your AI art. ComfyUI's upscale with model node doesn't have an output size option like other upscale nodes, so one has to manually downscale the image to the appropriate size. Uses face Detailer to enhance faces if required. Still working on the the whole thing but I got the idea down You guys have been very supportive, so I'm posting here first. Ideally, I'd love to leverage the prompt loaded from the image metadata (optional), but more crucially, I'm seeking guidance on how to efficiently batch load images from a folder for subsequent upscaling.

Because the upscale model of choice can only output 4x image and they want 2x. It is intended to upscale and enhance your input images. These comparisons are done using ComfyUI with default node settings and fixed seeds. 5 denoise (needed for latent idk why though) through a second ksample. This is not the case. Also ultimate sd upscale is also a node if you dont have enough vram it tiles the image so that you dont run out of memory. We would like to show you a description here but the site won’t allow us. After 2 days of testing, I found Ultimate SD Upscale to be detrimental here.

(206x206) when I'm then upscaling in photopea to 512x512 just to give me a base image that matches the 1. I wanted to know what difference they make, and they do! Credit to Sytan's SDXL workflow, which I reverse engineered, mostly because I'm new to ComfyUI and wanted to figure it all out. So I basically want to select multiple images from my drive so that the upscaler scales all the images I have selected, using the same sampler settings and whatnot. If I want larger images, I upscale the image. I have a custom image resizer that ensures the input image matches the output dimensions. it upscales the second image up to 4096x4096 (4xultrasharp) by default for simplicity but can be changed to whatever. This way I can upscale my images while I am away from my system.

X values) if you want to benefit from the higher res processing. Hires fix with add detail lora. The issue is likely caused by a quirk in the way MultiAreaConditioning works: its sizes are defined in pixels. I liked the ability in MJ, to choose an image from the batch and upscale just that image. Until now I was launching a pipeline on each image one by one, but is it possible to have an automatic iterative task to do this? I would give the input directory and the pipeline would run by itself on each image. Enhance image by adding HDR effects. But i want your guys opinion on the upscale you can download both images in my google drive cloud i cannot upload them since they are both 500mb - 700mb.
