EBSynth is pretty much a “style” transfer deepfake, wherein it animates a scene using the style of another artist, or using a scene thats been repainted to match a different style. See the video below for further clarification:

Using this concept, we can pretty much transfer the “style” (which in this case is the single frame still image of ROTJ Jabba edited into ANH CGI Jabba) to the entire video and animate it using AI. Sorry if it’s a bit convoluted but after you watch the video, you’ll see what I mean.
