@MASAHARU_SIDE Well, no, it's not. Adobe After Effects reviews the source material and generates new frames between the missing frames, each based on the previous and next frames.
@MASAHARU_SIDE Wow, you shot on tape. Is the camera model preserved? Is it Sony Handycam? What software did you use for the installation? By the way, I slightly improved your video to 60 FPS, I can send.
