Just for fun, I used ffmpeg's `minterpolate` (https://ffmpeg.org/ffmpeg-filters.html#minterpolate https://ffmpeg.org/ffmpeg-filters.html#minterpolate) feature to raise the framerate of my Mad Max 2 Road Warrior DVD from 24 to 100 fps. The results were interesting.
If you pause the video and step through one frame at a time, it's very clear which frames are from the original film and which frames were conjured by the algorithm. There's no AI involved, so the algorithm doesn't really understand background from foreground, and objects in the artificial frames are distorted and unnatural. But at 100 fps you don't notice this, or at least I didn't, and motion seemed very smooth and fluid.
The soap opera effect definitely held. It didn't feel like watching a classic movie from 1982, it felt much more like watching a contemporary reality TV program. There was definitely a sense of realism, but the realism was not that you're witnessing an actual post-apocalyptic society clinging to survival. It was realistic in the sense that you felt like you're on a film set, and if you could just peek outside the frame you'd see George Miller and the camera and microphone operators with the lighting and rigging and make-up and costume departments hanging around the catering truck.
A lot of people felt that HFR ruined Peter Jackson's The Hobbit series (or was one of the many contributing factors) because it broke the pretense of fantasy. In my experience raising the frame rate did the same for The Road Warrior. Those outlandish costumes looked even sillier at 100 fps, but man those stunts are incredible! You do get a visceral sense of just how dangerous a lot of those stunts are. It's a miracle that nobody was killed.
