What is a video if not a sequence of images presented in rapid and variable succession, with different resolutions? The premise, simple, was in force for over 100 years when the first filming was made and is in force in the 21st century.
On the other hand, we now have powerful artificial intelligence algorithms, particularly effective in pattern recognition and replication, capable of analyzing each individual image (frame) of a video and improve, or replicate its characteristics.
Technology shortens distances and preserves memories
In this way it is possible to fill the gaps left by the primordial cameras. The maximum boxes like the one that in 1896 filmed the arrival of a train at a French station, or captured the garden of some elegantly Victorian Englishmen.
And, what happens when we combine 21st century technology with some of the first videos ever recorded? In addition, of course, the expertise of video editors with modern software and capable of editing and retrieving footage. A journey through time.
Above we see the example of the “Roundhay Garden Scene”, filmed in 1888, a simple walk of mere seconds in an English garden with a light touch of green and seconds of action. It is thanks to several processing algorithms that we can appreciate today an incredible and particularly clear result – from the 2:40 minute mark in the video above.
From the 19th century to YouTube at 4K at 60 fps, the “magic” of AI
Above we see the original footage – converted to digital format and published on YouTube. It is shaky, without detail, but we can still see the scene of a train arriving at the station. It is one of the oldest videos in the world and was captured in 1896, entitled L’Arrivée d’un train en gare de La Ciotat ”- the arrival of a train at Ciotat station.
Then revolutionary, this video capture exposed the photosensitive film, in quick succession, to capture several photographs. The result is the video that we can see above, without sound, and with the characteristic aspect of the time. It’s rudimentary.
On the other hand, after the work of Denis Shiryaev, youtuber, we can see the same source material, but improved. Thanks to the aforementioned algorithms, the software is able to analyze each frame individual and replicate several of these frames to fill in the gaps left in the original video. In this way, we are treated to a greater fluidity of movement – 60 fps.
Furthermore, this video virtuoso was able to replicate and multiply several adjacent pixels (information cells), thus increasing the video resolution to the 4K Ultra-HD standard. He also took the opportunity to add some audio, thus creating a complete and somewhat disturbing atmosphere that takes us to the 19th century.
A journey through time thanks to AI
Full of grain, with little detail, no sound and nothing fluid, this is how the capture of Louis Lumière in 1896 can be described. Now, in 2021 we can watch this indiscreet window in time, greatly improved to make us travel to this world of old .
As technology advances and the implementation of artificial intelligence increases and improves its effectiveness, we may see even more temporal barriers to be broken.
This is (only) one of the great contributions of technology and computing to society.
