ngl you should 😂
I don't know if PeerTube has the option, but with Odysee, there's an option to automatically sync your existing YouTube channel with Odysee. It will bring over the video, the description, and will be uploaded in full quality; the comment section will be separate though, so the comments on Odysee are by Odysee users themselves.
Edit: I now know that this banner is not an ad for Odysee's premium subscriptions as it may seem to be. Memberships are separate to Premium entirely. Memberships are like the "Join" button you find on YouTube, where you pay a donation to that specific content creator and may get bonuses such as a badge next to your name in the comments, early access to videos, etc. depending on what benefits the creator chose themselves. Odysee only gets a 5% cut from this. This is completely justified as being the only thing that is arguably an ad on the site, as it is purely there to help creators thrive on the platform, and it can also be hidden permanently by clicking the X at the top-right of the banner; so they aren't even being forceful about it either. The ads being removed were mainly referring to the pop-up ads that third-parties could place on the website.
