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

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?

Here's the FFmpeg documentation for x264, an open source h.264 encoder: https://trac.ffmpeg.org/wiki/Encode/H.264

So the encoding strategy is tunable for an encoder, but also there are different implementations that might perform differently. They all produce a h.264 video stream that's decodable by any standard player.
