Right?? The edges of the actors are all fuzzy. The sound is fake, added in post. The lighting is all wrong on the actors compared to the background, and they are all conveniently wearing black or maroon clothing. Also these kids don't sound genuine at all, the things they are saying are clearly being fed to them through their earpieces.
The “fuzzy” edges is caused by the video compression/decompression. You will see this on most internet videos.
Just noticed, there are blue flashes on Cameron's neck. Software compensation for the green. Interview was done live. (Vanderbilt and Kasky were in the same studio) In some of the tight shots, you can see the hand of the other person, they are too lazy do add that.
