Below you were asking if videos would have engagement, but I'm pretty sure this thing is not frequented much outside of USA far-right individuals and some FOSS enthusiasts. [You need to go into a site that actually has moderation to avoid the former. That far-right is obsessed with absolutist free speech.]
The issue with video platforms is that they use too much traffic, so unless you can figure out the resources to pull off a service, you can't do much. The only other potential site I know is Rumble but when I entered the site I was bombarded with US politics and they also have a "truth.social" account, so I have no trust whatsoever.
If you want a video platform that works as large social media then YouTube and TikTok are the only decent alternatives.
Otherwise, either self-host or find an instance that is reliable enough for you.
