Equinox VS Aerial

You can use Equinox, it's totally free and open source and the UI is great.

Equinox is an application that allows you to create macOS native wallpapers. Starting macOS Mojave we have such cool things as «Dynamic Desktop», «Light and Dark Desktop» types of wallpapers. With the help of the Equinox application, you can easily create those with a few clicks in seconds. Just select a suitable type, drag and drop your images and create your wallpaper.

Dynamic Wallpaper Maker

Equinox is a native macOS app that has an option for creating wallpapers that change their appearance based on time of the day.

Edit: there is a free app that does this and i didnt know about. its called Equinox Thanks to @AidenCP and @AWF_Noone for the suggestion.

I’ve been eyeing on Equinox. Looks very clean, but I haven’t personally tested yet.

I was debating where to put this, but It works as a wallpaper, so displays it is! Aerial is a free and open-source Mac screen saver Aerial is a macOS screensaver that lets you play videos from Apple's tvOS screensaver. This includes classic Aerial videos shot over various cities and locations (New York, San Francisco, China...), Earth videos from the ISS, and the new underwater videos introduced in tvOS 13. Starting with version 2.0, Aerial also includes videos from 3rd parties that kindly shared them, and you can also now add your own! Aerial is completely free and open source. You can follow its development here on GitHub, and even participate if you want. You don't have to be a developer, we always need help when it comes to translations in various languages, check here for more information (it's easy !). It's really cool, give it a go!

PSA to a Github repo to run the screensaver on your Mac

Get the screen saver for your Mac here.

If your footage was about 6 to 10 minutes (typical length for an ATV screensaver according to the videos I have saved), they might consider tossing a coin your way haha

Just found this one it's super nice https://github.com/JohnCoates/Aerial

That's a horribly outdated version linked in that video sadly, and that one no longer runs on recent macOS (because it's not notarized).

Just in case anyone wants to try it, please grab latest build here instead : https://github.com/JohnCoates/Aerial/releases

Or if you want an installer with auto updates, get it here : https://aerialscreensaver.github.io

Latest betas include Apple Music/Spotify integration, Speed control, and brings back the ability to put your videos anywhere (including an external drive!) on Monterey.
