I don't understand. What's the original vs deepfake comparison about? I know nothing of Star Wars (sorry), is there a third video it's based on or something?

Both original and new one tries to depict how a specific actor looked in the 70s.

There’s no ground truth to compare with other than the Luke skywalker character in the original Star Wars movies and which one looks most realistic

So there is a stand in acting, and both have replaced his face? Or is the deepfake done on top of the original that already looks like the actor?

There was a stand-in and the tv show computer generated the character replacing the stand-in. And then a YouTuber took that footage and made it look even more realistic.

The deepfake will have been done by a youtuber over the top of the tv show version (the one on the left is from the show)

One thing to note is that the 'original' (CGI actor) was already a bit awkward because things like the lip sync were off compared to a real actor.

That said, the facial animations for Leia in another video he made (they did a digital version of Leia for Rogue One, he deepfaked on top of that) actually improved with the deepfake version.

They are both deepfakes. But one was made by hollywood, and a better one was made by a youtuber.

Though the Youtuber's deepfake is a deepfake overlaid on Hollywood's attempt, so all of the lighting and motion capture acting is already done.

A key difference is that in at least the case of the movie "original" they were digital 3D heads, complete CGI. The youtuber's deepfakes are old footage that an AI overlays onto the face.
