I’m working on a health series about seniors and sexuality for an educational broadcaster. I need to clean up some old grainy educational health films from the 50s/ 60s that will be included in the series and one particular film has a few shots of full frontal male nudity. Nothing sexual..just black and white 1950s, no nonsense, for educational purposes only type nudity. Starlight precise does a good job at making everything look better but it introduces a problem I’m not sure how I’m going to deal with .. it tends to change the male anatomy into something that looks like a large thumb complete with thumbnail. It’s funny and creepy at the same time. If the person moves a little in the frame it might fluctuate between a thumb and the real thing but when it’s a thumb, it’s most definitely a thumb.
Any insight as to why this happens and how to fix?
Sounds like the model is very confused on anatomy and at times converting it to a thumb. This might be one of the times, where running a first pass with Proteus, or another model to help define the content will help the Starlight Precise model understand in a second pass.
Try upscaling the video by 2x with Proteus and then feeding that into Starlight Precise to see how it handles it and if it reads the anatomy correctly instead of registering it as something else.
I tested it on a porn video with an original resolution of 480x352, upscaling it to 1920x1408. The video shows both oral and vaginal sex — there were no distortions or artifacts on either the female or male genitals. However, I admit that problems may still occur, since the model’s training data most likely did not include NSFW content, though maybe it’s for the best, it would be pretty frustrating in some cases to see male members on your hands instead of fingers ))) It’s possible that the issue appears when the source material is of very poor quality.
Thanks for testing. It’s definitely happening on my footage which seems underexposed to start with. I’ll try a first pass with another model 2x upscale before starlight as suggested and see if that helps
