In 1987 Rick Astley's "Never Gonna Give You Up" was just a song – albeit, a popular song. Today, the same infectious tune from a young Canadian pop star has come to symbolize much, much more than a (now pretty corny) moment in musical history, especially if you've ever trolled, or have been trolled, by someone on the internet.
"Rickrolling, alternatively Rick-rolling or Rickroll, is a prank and an Internet meme involving an unexpected appearance of the music video for the 1987 Rick Astley song "Never Gonna Give You Up". The meme is a type of bait and switch using a disguised hyperlink that leads to the music video."

The original version is also back up on Revideo's channel, albeit in a shorter, more copyright friendly, length of one minute. The entirety can still be seen and downloaded via the Internet Archive, however.
Instead, Revideo's update to the Astley cannon uses AI to interpret and add information to a digital file with the help of machine learning.
Topaz Video Enhance AI, like other software of its ilk, uses a neural network trained on "thousands of video pairs" to reinterpret a video through sharpening, smoothing, resizing and eventually producing something that appears closer to frame rate you might expect from live sports or a soap opera.
