I'm working on a video hosting project and I would like to know if I'm converting my videos quality the right way.
my equation is: newY=(y/x)*newX
so 1080p is:
1080x460 than 720p 720x306 ... 480x204 360x154 240x102 144x60
My problem is 360 and below comes out in a terrible quality. comparing that to youtube I'm wondering if they are actually changing the video resolution or just changing the kb/s?
