How to get the BEST QUALITY in PIXAI with the LEAST credits possible (3 options) | TUTORIAL
Like my video so I can win some credits in PixAI :D This step 2:00 is important to fix eyes, but I didn't show the result.
Hope you enjoyed the tutorial! This video makes better tips to get the best quality than my old tutorial: • BEST WAY TO FIX YOUR PixAI IMAGES - How to...
Denoise TL;DR is 0.1-0.2: Very low changes, 0.4 low changes, 0.5-0.7 more and more different but maintaining composition
For enhance, use denoise 0,5 if you like the image but you want some changes. 0.55 and 0.6 will fix your images but the image will change.
For the lowest credit usage, you can use enhance with 0,4 weight and x1.4 resize. Only do it if you already like the image as it is.
Note: I forgot to say it in the video, but for the 3rd option try to enhance a image of 20 steps (free) with 0.4 weight with fix face and then enhance for 400-700 credits. It will be 3 steps but it is the cheapest way.
TL;DR. How to generate good quality?
Option 1- Use x1024 or HighRes fix to x1024 resolution with face fix activated.
Option 2- Generate images with normal gen and less steps, then use face fix in slow priority with "use as a base" option with weight 0,4 (1 image is 50 credits) and then enhance with slow prio (this step is around 700 credits. This is slower process but cheaper and also will create worse hands, but enhance may fix it if hands aren't too bad).
Option 3- Normally the best one, using HiRes fix. It is the most expensive and the most random one, since you won't be able to fix it later as it will cost more credits. Good on very few models.
Due to changes in PixAI my current resolution for HiRes are 512x344 or 512x336.
Important: For enhancing, if you are using more than 1000 credits you need to change the sampler to another one cheaper before enhancing. If it doesn't work, generate a new image. Click on base "Use as base image" and add 0,1 or 0,05 denoise with a new sampler.
With "Use as base image" option you can change an image to give it the style of other model. Give it a 0,05 to 0,4 denoise and most of the times it is free. This works great with some models as it allows you to give it more steps in that denoise phase (30 or 40 for example) and then you can use normal steps (20) to upscale. This is very good in some models that are both good in 20 and 30+ steps.
FAQ: Why 640x430 resolution? Because it is the default that Stable Diffusion uses while using 768x512. It can work with normal resolution too, but you know... More credits.
Too long; Don't read:
Which method is the best to get the image you want with the lowest credits in PixAI? For closeups, I recommend just using 1024x resolution. For medium/full body: Generate a image with normal resolution and 20 steps of Euler a or more than 16 steps from DPM++ samplers. Use the option "use as a base image" with face fix. If your image is already good, upscale it freely. If it's not, keep using "as a base image" with the help of LoRAs. Alternatively, enhancing it you can fix it if the model works great in higher resolutions.
Which method is the best for the best quality with the lowest credit usage? (All without prio)
If you use "High res fix" to x1072 from normal res it will cost you 700 per image. Only enhancing will cost you 600-800. If you use "Highres fix" to x1024 res from 640x430 res will cost you 500 per image. This last one is the best for me but it is more random and you can lose credits, the way to make it less random is to copy a seed. You can also gen x4 images with face fix and high res at a cost of 1750 credits. Enhancing is the best if you know which image you want, but it is less powerful than highres fix so you need at least decent eyes.
For closeups, I recommend you (with a model that suits) to just use x1024 resolution and maybe increasing steps a little (It usually works better, but it is not necessary, only for better quality).
