Why is there Part 1-3

Because the platform only allows uploading videos under 3GB, I usually shoot in 4K60fps high bitrate and a full video is usually 18GB long. Both OF and JFF can upload large files normally. Of course, it looks very high-definition when watching on TV. Here, due to restrictions, it is usually split into three parts and is 1080P 30fps normal bitrate. It's not that I want to restrict everyone, but the platform. So where to subscribe is your choice.
