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?

Well yes, they have a lower bitrate, but why same quality as a bigger bitrate video? Same resolution, codec, frame rate...

If you do multiple passes you can alleviate some of the downsides of low bitrates. You can always easily spot it in dark areas. I despise watching space movies or shows on streaming services because of the resulting excessive banding artifacts.
