When we are talking about YouTube I don't think platform matters.
Quality, format and resolution for sure though.
What you're looking for sounds very specific..
The only program I've used to do it is Download Helper.
For Firefox, it's an add on but I don't think they have 480p.
I could be wrong though, think it depends on the file.
You try to grab while it's streaming, the add on sees it, then grabs formats to download.
You could try that, or research, might have to dig heavy.
Good luck.
