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?

    Resolution and quality are different things, especially when different codecs are used for data compression. An AVI i record for acreen capture might hit 250 MB, running that through ffmpeg to get an mp4 might be 20MB, if i drop the quality but same resolution then sometimes 7MB
