Sometimes you may notice that your YouTube videos are zoomed in. Recently, smartphone manufacturers have been increasingly releasing devices with displays that have an aspect ratio of 18:9 (or 18.5:9 in Apple's case).
This leads to the fact that traditional video, shot in 16:9 ratio, does not completely fit on such displays, when it is played back on the screen, black bars are displayed. YouTube app now scales video for displays with aspect ratios other than 16:9. Some manufacturers build pre-installed solutions into their skins that allow video to be stretched in such a way as to completely fill the display with images without displaying black bars. For those cases where smartphone manufacturers do not implement such a function in the interface, YouTube offers its own solution. The YouTube app now has the ability to scale the image to fill the entire available display space. Although, in some cases, such scaling may degrade the image quality. The new video scaling feature for displays other than 16:9 is available in the YouTube app starting with version 12.44. There are two solutions to the described problem: use a special browser extension or a third-party player with a video scaling function.
