I've seen a number of these deepfakes, both SFW and NSFW, a lot of the unconvincing ones are done by people that haven't specified a long enough training time (12+ hours normally IIRC) or produced enough res image data sets / were testing the data for first time. You have to find a target actor/actress that looks similar to what you are deepfaking (e.g. family member)
