I created this video to show people how important it is to have good bit rate in videos, some people think that if you have 1920X1080 pixels the quality should be automatically good,so let them see if it is true
both videos are identical processes only thing is changed is bitrate
original recorded file had: Overall bit rate : 162 Mbps



Note this is source video files parameters youtube converts files which are uploaded as result youtube files are worse quality than source files
