I am using the workflow with the template on runpod yes, but aparently adding a new encode more uncensored called "heretic" fixed de problem, and now the results are better. Now I see that the model does not know the anatomy of the penis and vagina...I guess that will be fixed with LoRas in the future.
Another "problem" that I saw is that I cant make them having sex fast, is like they are in slow motion or something, a little bit robotic. I am currently using only i2v.
Edit: it seems that the longer the duration of the video is, the worse the result will be. 5 secs are good but more than that not so much.
