i mean not really
480p is just not a 16:9 resolution
16/9 = 1.7777777777777
if you multiply 720 by 16:9 you get 1280
if you multiply 1080 by 16:9 you get 1920
Those ARE 16:9 resolutions
but if you do the same with 480p
what is the width?
853.33333333333
so you can't use it as is, you need to either set it to 853 (which sucks because its an odd number)
or 854 (which also sucks because its not the correct rounding) (this is the most common approximation tho)

so, yeah, there is no such thing as 480p "16:9"
480p was originally meant as a 4:3 resolution (640x480)

@meluzzy@woof.tech even 1366x768 or 1360x768 aren't standard res:s, they are "similar" to 16:9, so theoretically you can upload a video that's 853x480 (almost exact 16:9), 768x480 (16:10) or 747x480 (14:9) and it will be treated like a 640x480 (4:3) video.
it's all about encoding

@meluzzy@woof.tech also 480p is not applicable to an aspect ratio in particular. we're used to 4:3 640x480, but 480p is a resolution that has a height of 480 px:s (and it's not interlaced).
if you want to say 4:3 480p you say VGA, 16:9 720p is HD, 4:3 768p is XGA, ≈16:9 768p is unsure: the most common is 1366x768 FWVGA, and others are the same
