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?

    A lot of the data in the video file you take isn’t that visible but it’s there for when you put it in editing software

    For example: if you took that lower sized YouTube rip and threw it into editing software to tinker with the brightness (as a simple example) you quickly start getting artifacts whereas the video you took would be able to handle the editing without the artifacts much better as there’s more data to work with

    Basically the YouTube video has had all the extra data scrapped off that it doesn’t need because it’s not going to be edited, it’s only going to be viewed
