Why are camera taken videos at the same resolution way bigger than ones ripped from youtube? (self.technology)

A 4 min 1080p30fps video taken with my phone camera is 518MB, While a 12 min 1080p30fps video ripped from youtube is 341MB, both are using mp4 h.264 as codec and the youtube one isnt of lower quality, so why this big difference?

It' the individual frames that are compressed, essentially the video is unpacked and detail is culled from averages across multiple other frames beside it. So if the top of the video, for example the sky, doesn't change then that part will be kept static.

It's not so much properties about the video, but properties about each frame. I can take a 1080p image and blow it up to 8K in GIMP, but it's got the same detail as a 1080p image.
