With help from a neural network, Denis takes original cinematography of New York City in 1911 and uploads it as an cleaned, upscaled, high-framerate, colourised YouTube video. It’s pretty remarkable: compare it to the source video to see how much of a difference it makes: side-by-side, the smoothness of the frame rate alone is remarkable. It’s a shame that nothing can be done about the underexposed bits of the film where contrast detail is lacking: I wonder if additional analysis of the original print itself might be able to extract some extra information from these areas and them improve them using the same kinds of techniques.
In any event, a really interesting window-to-history!
