The document speaks to the technology but make no mention of what people thought after seeing the demonstration. Generally speaking it seemed very clear that the benefits of 48 frames to the eye was easily seen. Motion judder was eliminated. The picture looked more natural.
When 60 frames to the eye was shown, not only was the judder removed but the foreground ‘resolution’ popped out. In a sense, this is unnatural since when one is focused on a distant object the foreground objects are not focused. On the other hand, directing with focus is a tool that directors use. If the director doesn’t want to limit focus, it is nice that this resolution becomes available.
