Although many understand the reason behind that strange flicker seen on older CRT televisions (Cathode Ray Tube) when viewed through a video camera, Gavin from The Slow Mo Guys, shows us that there’s a lot more going on that our brains simply cannot compute. While the simplified version is that the refresh rate of the screen is out of sync with the shutter speed of the camera, there’s actually a lot more going on that cannot be seen with just the human eye. With the help of his remarkably advanced ultra high-speed camera, Gavin demonstrates above.
So then, what exactly is happening when we play a game like Super Mario for NES? At 1,600 FPS it is revealed that the image is in fact a line of pixels that scrolls from top to bottom at such a speed that our brains subconsciously stitch the full image together. However, what happens at 11,800 FPS and beyond is a different story altogether. Without spoiling too much of the video, just know that this is the furthest the team over at The Slow Mo Guys has ever pushed their cameras.
Watch the entire video to see how an old CRT TV compares to modern-day LCD and LED screens. In other news, tread lightly while messaging over Instagram, as DMs now show your activity status.
