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?
720p is fine, but I'd prefer 1080p most of the time.
It mostly just comes down to bitrate. A 4k video at 1Mbps is probably gonna look like shit. My drone and my go pro shoot 4k footage at 60Mbps h265 and that looks amazing. But if I'm acquiring a fuck ton of movies I'm not gonna download that shit at that bitrate. As long as the video is like 1080p and 5Mbps or higher I'm happy. If the file size is >6 gigs for a movie I ain't downloading that shit even if I can, and that's with a 1gb symmetrical internet connection and a 30TB NAS.
