It's part of research I've been doing over many years in the realm of image processing, as those on this forum might know. In particular I've been very much into how Super8 (or any other gauge) might be processed in the digital domain. The following is one of the tangents I've been taking in such research. It's not Super8 but it's part of research towards algorithms that would operate on Super8.
The main thing here is that the videos are not computer generated in the usual sense. Rather, they originate in natural photographs (in this case digital photographs) rather than in some 3D artist's imagination. That's an important distinction. Photography proper, in my books, is about images that originate outside of our imagination. Not in some notion of objective reality (I reject that as well) - just simply outside of subjectivity.
The results here are basically the result of "stitching" together 20 individual photographs of the same tree, each taken at different angles. The software estimates, from each photograph, what the three dimensional shape of the tree would be (quasi-analogous to the way our brain might do the same, but I have no idea whatsoever how our brains actually work). After that, the individual images (photographs) are then projected back onto the three dimensional shape, to form a single volumetric image in virtual space. I then create a new camera angle on such - for example, one that might move around the tree, and render such:
