youtube-clone-nodejs-api VS Zusam

You can keep video separately for example by utilizing your own youtube by self hosting VueTube or simply use peertube for video while keep communication part by utilizing either some forum software or mattermost or matrix

But I didn't like the fact that it was tied to facebook. I decided to put into practice what I've learned that year at my informatics school and created forum written in php. It was not much but we liked the fact that it was ours.

Ten years later, I'm still fiddling on it and it has grown to a real open-source project that you can find on github [0]. It's still primarly here to serve me since I'm the only maintainer but starts to be driven by external propositions. It's meant to be easy to deploy, easy to use, cheap in resources and reliable.

Would Zusam work?

You could also add a link to the project and not just your blog: https://github.com/zusam/zusam

I actually came across Zusam which does video processing to some extent, so I'm thinking I'll take a closer look at that and see whether it does any downsizing or at least embeds it (all the forums I've tried so far just attach a video as a file attachment, and you download to view).
