I run my face swap locally on my personal system. Though, it takes hours, sometimes a whole day just to render a 3 to 6 second video.
My PC is of the lower end (got it in 2019, think it was manufactured in 2018) , so it cant do localized stable diffusion and I'm still figuring out which local LLM I should use.
But I can do deepfakes now no problem. Got my rival/bullies face attached to a male porn star from 'Lilhumpers', of him 'humping' the air near a blonde milfs ass.
I also created a 5 second video of my mom's face attached to a porn star playing with a guys cock. Its genially impressive.
I would never release those videos though. Not for a very high high price anyway.
Plus, due to the length of the videos and time it takes, it would be a slow process.
