I tried to make a couple of videos by extracting faces from a few videos and then trying to swap the actors inside the videos. Every single one of my attempts failed before it began (literally). I forgot the actual error since it was a while ago but it was something a LOT of people were asking about online and thus I got a LOT of suggestions (most of them involving setting the same setting to on/off, I forget which).
Needless to say, I tried every tip I could find and no matter what I tried it all ended up stopping before it began. learning started processing and preparing and then... sorry, but no.
For my one video I extracted 8000 images and for the other I extracted 32000 images so clearly the QUANTITY of images I had was not the problem but I am wondering if the QUALITY of the very small, blurry little faces might have had anything to do with it.
Is there a minimum size for extracted faces? 1k? 4k? 20Kb? None?
Or better yet, since there are so many Arnold fakes out there, so many Stallone, so many [insert X], is there no repository where one can get a set of extracted faces that have been proven to work? Sure you won't get "everyone I ever dreamed of" in such a list but at least it might be a good source (for ppl like me) to start experimenting with (without wondering "Am I extracting the faces wrong or what is the problem?")
