Grabbing the perfect screenshot from a video hasn’t always been the easiest task on desktop or mobile. Although you could always use the usual screenshotting tools on either platform, it wasn’t always possible to get a clean output without menus and player controls being visible, unless you cropped a significant portion out of the picture. Fortunately, this has now been somewhat remedied on desktop, and an Android solution appears to be on the way as well.
“Save Video Frame As…” option in Google Chrome Desktop
However, recent code updates indicate that Google will soon allow you to save video frames directly from YouTube on Android devices. This was also spotted by the same user via yet another commit on the Chromium Gerrit repo called “Mark copy/save video frame features as disabled on Android,” with a description that clearly states “These features are not implemented on Android yet. To be prepared for the implementation, mark them as disabled until they are ready to launch.”
This indicates that plans are in motion to bring this handy tool to Android, although there is no clear indication of how it will be implemented. Since YouTube has its own dedicated app on Android, my guess is that it will be part of the interface and added as an option within a video’s settings, where you would normally choose the playback speed and video quality. This is just a guess, though, since there are no screenshots available as of yet.
