Twitter is adding autoplay to GIFs, Vines, and native videos on iOS
Twitter is turning on automatic playback for certain types of media in your timeline through an update to its iOS app and its website, the social network announced.
Starting today, users will notice that native videos, GIFs, and Vines all autoplay directly in the timeline when browsing Twitter without the need to tap or click to initiate playback. Sound playback for native videos and Vines will still require tapping or clicking to play to avoid hijacking the experience. Users can also initiate full playback by rotating the iPhone to landscape mode when viewing an autoplay video.
