If it's for reduced storage space on your toaster or phone, just re-encode it, takes almost no time at all if you have your ducks lined up in a row, or in other words, if you care then bother to climb a little hill to learn how to do that.
Since I'm not a snob about the maximum bitrate to quality ratio, when viewing it on my toaster on a tiny screen, I can re-encode that in about 2 minutes, literally two minutes with a video editor that can use NVENC due to having an nvidia video card, if I need fast instead of the idealized bitrate to quality ratio that I will never see on a 480p viewed on my toaster.
I don't really have a toaster that can display video, but I can downgrade quality of anything to reduce archival storage space and do that with shows where video quality doesn't matter like comedy shows where nobody cares if I can see the pimples on the performer, as long as I can hear the joke.
However I don't live in this forum so it may take a while for me to notice that you want one.
I will say this, that if you want smallest file size on a 480p, re-encoding is usually going to result in a smaller file size than the distros I'm seeing, especially if done to xvid. Who needs xvid these days anyway? Even my toaster oven doesn't need that.
