Now way near as bad as I thought it was gonna be.
I have experimented with rendering video with ai also and know how difficult it is. Good effort.

My own attempt:

This video thing needs at least 2 months to be decent, but it's great to get into it to be ready for the video explosion.

I'm pretty sure some tiktokers are worried with this stuff, if they know it exists yet...

What extension is for video? i used img2img with extract all frames from video and do a batch with it, then resemble it.but result not good.

I have run my tests and hereby I release my Lora upon the universe.. Or at least on F95zone.
My Lora is based on character named .
Be careful with this one, it is very potent. I recommend not go higher than 0.8 or the sky might come down.
The sweet spot is probably 0.4-0.6 ish but I estimate it's usable between 0.2-0.8 .
Main tag is "Kendra", but it can of course be used without.
I'm looking forward to see what other people will create with it.

I'm developing a theory, may be everyone knows it already, but as my prompting skills 'improved' I started to feel like I wasn't getting all the results I wanted, stuff wasn't intricate enough, detailed enough.

So I think the more prompting and words you add, the more you have to higher the CFG and the steps.

Just an idea to discuss...

I think the intricacy is resolution based. Whenever I have a partial shot hips the texture there is out of this world. But the texture disappears the moment I get a full shot of a person. And then I see the texture again in the MrFox's HiRes renders. So, if you want intricate detail down to the pixel, HiRes is where it is at. That's my observation, no idea if shared.

You are probably right, I forgot about resolution, after all this time I still can't understand what is CFG and sampling steps doing to be honest xD

edit: the problem that I have is that when I start the picture with higher resolution, even with the same aspect ratio, sometimes I get split images, or a collage of images, so clearly there is something I'm missing

CGF (classifier free guidance) is how much "creative freedom" you give SD and how much you "force" it to adhear to the prompt. If you set it too high the image can get "burnt" but there is a Dynamic Tresholding extension to fix this. There is also an anti burn extension. You can find it in extensions tab/available press "load from". The sample steps is how many attempts SD does to try improve the image. More is not necessarily better. It is better up to a point, then it is changing the composition or add weirdness and artifacs etc. The Hires steps is similar but it has the added function of increasing the quality of details and fidelity etc. Again this is also not something to just crank it to max.
A good rule of thumb is 2x the sampling steps. Denoising Strength has to do with the latent noise that SD creates the image from. I guess that it is makes the noise more defined. Less means the image has less change, more means more change to the image. I perceive it also as how much "freedom" we give SD.
Less Denoising means less "freedom" More denoising mean smore "freedom".
For Hires Denoising Strength, 0.3 works well for me.

gif2gif. You can find it in Extensions tab/ Available. Press "load from" .
thank you so much, have to try.
Nice done on lora, i want to try it, but seem unable to connect for download.

For what i've understand it's work like "how much fantasy you need?". let me explain: i work at cfg 11 because is a good value i find work for most prompt i try. but when i do some extreme fantsy promp, especially when you want mix person with animal, i need to lower cfg to 8-7 to get result i want, otherwise i get a person and a animal in image,without mix.
Just try same prompt at different cfg to see what model you are using do.

Yes when you use a higher sampling resolution, SD has a problem handling this and you get monstrosities.
Such as conjoined bodies etc. In rare cases you can get a split image. Make sure that you didn't forget to turn of batch count or batch size. If this is set to 4 you will generate 4 images and in the end an image grid or collage. Batch count is how many seed steps you want, batch size is how many images from the same seed you want.
Example:
If you use batchcount 2 and batchsize 4, you will use 2 different seeds and 4 images of each, 8 images in total.
This is a very useful tool to generate many images in the search for the perfect one.

That's golden info for me, I never knew what the difference was, and never knew how to generate more than 1 image of the same seed.

Today i installed xformers, and oh boy, this shit bussin'. Went from "out of vram when generating 512x768 with x1.5 hires upscale after 7 minutes" to "ez 512x768 x2 hires upscale in 3 minutes". And tbh after some testing, i see no change in quality whatsoever. And finally i can generate some portrait mode pics :BootyTime:

It increases the vram usage though. So it's not an option if we are trying to use as high resolution as possible. It's a shame that it is generating 2 or more at the same time when using batch size. But there are good news. You can use xy plot script instead.
Example:Set seed as X axis and something else for Y axis that you just repeat as many times as you want images of each seed.

I don't use hi res for txt2img, upscale in img2img phase so it's not a problem for me

xy plot started to give me errors like 1 month ago and there was no way to fix, and now I don't even want to think about it, I don't enjoy much using it anyways.

Xformer doesn't change quality. The rumor is that it makes the image generation less predictive. In my experience, this is not a thing. If there is an increase of variation it's so small that you can't differentiate it from the normal variation. Meaning repeated generation of the same seed and same settings. Each image will be slightly different. But this will happen regardless if you use xformer or not. Imo more variation is not a bad thing regardless. Yes, do use xformer. Any boost in performance we can get is well needed.

Oh man that sucks. I use it all the time, it's great. I run comparisons very often to weed out the best settings, wich sampler to use and many other scenarios. For instance I made several different iterations of my Lora that I could compare with the same prompt and seed thanks to plot script. I have never had any error specific to this. If nothing else works a simple re-install will likely fix it.
