At the end of the day, my hardware is not appropriate for SD, it works only through hacks like tiling in A1111. And while that's fine for my hobby experimenting, I would like other people, or even myself once I finally upgrade my desktop, to be able to recreate my images in better quality, as closely as possible (or even try and create variations).
I already make sure to keep the "PNG info" metadata which lists most parameters, so I assume the main variable left is the RNG source. Are any of the options hardware-independent? If not, are there any extensions which can create a hardware-independed random number source?
Good call-out. My (naïve) understanding is that tools like tiling VAE to handle low VRAM, and lowing steps in the more stable of the samplers, are going to have a generally negative impact on the result, and a very similar image with better detail could be remade using similar variables on better hardware. Maybe that's a bit idealistic. Like you said, the seed mode usually changes images with size. (You said 'usually', is there a way to minimize this?)
edit: I'm aware 'better' and 'higher quality' are vague and even subjective terms. But I'm trying to convey something beyond merely higher resolution.
I have a few examples that I hope retain their metadata.
Seed mode is… basically, I stopped using Automatic1111 a long time ago and kinda lost track of what goes on there but in the app I use (Draw Things) there’s a seed mode called Scale Alike. Could be exclusive, could be the standard everywhere for what I know. It does what it says, changing resolution will keep things looking close enough.
Edit: obviously at some point they had to lose the bloody metadata….
