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?
3I'm a little confused by your question. 1080p is 1920x1080 (WxH), and 720p is 1280x720. 360p would be either 480x360 (for 4:3) or 640x360 (for 16:9). What's your equation supposed to be calculating for you? – Ƭᴇcʜιᴇ007 – 2013-09-26T18:34:22.383
You're only dealing with the spatial resolution, not the quality which is affected by many factors like compression level. – sawdust – 2013-09-26T18:41:33.963
You shouldn't expect good quality at lower resolutions. I mean 360p on YouTube is horrible quality. – Ramhound – 2013-09-26T18:47:17.307
