Netflix has begun testing variable playback speeds on its Android app. The feature allows users to slow down their content at 0.5x or 0.75x its original speed or speed it up to 1.25x or 1.5x. It appears the new playback speed feature will be present next to the audio & subtitles toggle.
Playback speed toggles have traditionally been reserved for podcast and audio-book apps as some users prefer to consume that kind of media in a faster manner. On the video front, YouTube has had its playback speed control which ranges from 0.25x all the way up to 2x for several years.
As of now, there is no word on when this feature will be available to the masses nor if its also being added to other platforms.
