I have been toying with the idea of various types of videos, including intermediate level painting videos, video game retrospectives, and some personal worldbuilding project videos. I don’t want to feed the YouTube machine, but also don’t want unsustainable expenses. I’ve looked at a few of the various not-YouTube alternatives but it is difficult for me to get a good read on that landscape.
Someone suggested AWS S3 but that is ridiculously expensive. How much viewership do you expect? Self hosting is not that expensive unless you have big volume. Or you could just seed some torrents. I would stay away from “platforms” since afaict they all have the same disease as youtube, just in its less advanced stages.
