If you're starting a brand new account on PeerTube (or on any Fediverse server), it's not a good idea to post lots of content before you have followers.
The only people who can see your posts on the Fediverse are those on your server, those on other servers who follow you, or those on other servers who see your post shared.
If you post all your best content up front on a brand new account with no followers, no one outside your server will be able to see it. Even if they follow you later, the posts you made before that will not be visible to them, because Fedi platforms don't backfill old posts on accounts you follow.
It's much better to gradually add videos (or other content) as your follower numbers grow.
You only need one follower from a server in order for everyone on that server to see your post. Even if you only have a dozen followers, that's up to 12 other servers that can see what you post.
