I make videos full-time on multiple stores and although it's demanding, I like it a lot and am willing to devote a lot of time to it. Try to gauge what site makes you the most money, what type of videos make you the most on your highest-paying site, and so on. What have you tried so far?
As well, all of the sites you've mentioned do have a pre-scheduled upload feature (as ashley jane pointed out). But if you're spreading yourself too thin, focus on your top 1 or 2 sites.
