YouTubers Are Upscaling the Past To 4K. Historians Want Them To Stop

YouTubers are using AI to bring history to life. But historians argue the process is nonsense. From a report: The first time you see Denis Shiryaev’s videos, they feel pretty miraculous. You can walk through New York as it was in 1911, or ride on Wuppertal’s flying train at the turn of the 20th century, or witness the birth of the moving image in a Leeds garden in 1888. Shiryaev’s YouTube channel is a showcase for his company Neural Love, based in Gdansk, Poland, which uses a combination of neural networks and algorithms to overhaul historic images. Some of the very earliest surviving film has been cleaned, unscuffed, repaired, colourised, stabilised, corrected to 60 frames per second and upscaled to vivid 4K resolution. For viewers, it almost feels like time travel. “That is something that our clients and even the commenters on YouTube have pointed out consistently,” says Elizabeth Peck, one of Shiryaev’s colleagues at Neural Love. “It brings you more into that real-life feeling of, ‘I’m here watching someone do this’, whereas before you’re looking more at something more artistic or cinematic.”

But these vivid videos and images haven’t wowed everyone. Digital upscalers and the millions who’ve watched their work on YouTube say they’re making the past relatable for viewers in 2020, but for some historians of art and image-making, modernising century-old archives brings a host of problems. Even adding colour to black and white photographs is hotly contested. “The problem with colourisation is it leads people to just think about photographs as a kind of uncomplicated window onto the past, and that’s not what photographs are,” says Emily Mark-FitzGerald, Associate Professor at University College Dublin’s School of Art History and Cultural Policy. Peck says Neural Love makes clear to clients the huge difference the company sees between “the restoration aspect and the enhancement aspect.” They see the removal of scratches, noise, dust or other imperfections picked up during processing as a less ethically fraught process to upscaling and colourising. “You’re really returning the film to its original state,” she says. That’s not a view many academics hold, however. Luke McKernan, lead curator of news and moving images at the British Library, was particularly scathing about Peter Jackson’s 2018 World War One documentary They Shall Not Grow Old, which upscaled and colourised footage from the Western Front. Making the footage look more modern, he argued, undermined it. “It is a nonsense,” he wrote. “Colourisation does not bring us closer to the past; it increases the gap between now and then. It does not enable immediacy; it creates difference.”
