I have a very slow Internet connection (5 Mbps down, and even less for upload). Given that, I always download movies at 720p, since they have low file size, which means I can download them more quickly. Also, I don’t notice much of a difference between 1080p and 720p. As for 4K, because I don’t have a screen that can display 4K, I consider it to be one of the biggest disk space wasters.
Am I the only one who has this opinion?
If each frame in the media contains the exact 1920 × 1080 pixels …
This image has the same number of pixels on the top and bottom half, but you can probably see the bottom half looks worse. That’s what lower bitrate does. It’s like turning up the compression on a jpg – you are not getting the exact same pixels, just the exact same image size.
