You can make porn with a cellphone. Nobody will care.
You could make a cellphone-porn site, and people would go to it.
Porn is a tool, doesn’t need to look good. Besides, poor quality might make it look good anyways. If not, use makeup.
Do they make noise removal for video? That’ll make your video look better, use the maximum setting. Hopefully it lets you specificity what noise is, like hair. Then it’ll remove the hair for you.
If you have an actual camera, that lets you specify the ISO, shoot on the highest ISO, then use noise removal.
