I don’t know who did this, or how he did it, but he did a good job.
I had tried to remove the blue filter when the release first appeared, but it was beyond my skills. The only way I could figure out how to do it was to strip it to black-and-white, then re-colorize it with AI, but I didn’t have the ambition to do that. The person who did this video may not have used that technique, but whatever he did, it worked.
Here’s the original, with the blue filter

This is Topaz AI once again. It has what they call the “creative reimagine” feature where it essentially paints over the original footage with AI enhancements.
So think of it like avatar. It’s a CGI creation based on real photography and motion.
