This is an interesting video editing technique. For season 2 of “Video Game High School”, the crew filmed all of the live-action sequences in 24 FPS. But all of the rendered in-game scenes are 48 FPS. It’s VERY noticeable in the trailer, and at first glance I think it’s quite cool. It really separates the real from fantasy by making the fantasy look more realistic than real life, which really contributes to the storytelling.
If you watch the trailer, follow the instructions carefully to get the 48 FPS version.
On the non-technical side, I highly recommend VGHS. It’s extremely cheesy and follows the sports-drama trope really closely, but it’s still excellent.
