Fascinating. I am not sure how he did this in 1902 as they didn't really explain how the RGB filter was used to create color in a moving picture? Did I miss the explanation?
I had the same sense: the explanation was clear enough but no detail except for the spinning tri-color filter. One can almost guess he adapted color filters to film like the popular flipping card arcade viewers of the 1880's and 90's --- but who knows?
This appears to be a feature news report, hopefully a more detailed video will follow.
