Adjusting video playback speed
One of the neater tricks you can find in your iPhone is increasing or decreasing the playback speed of videos. Not many people are aware of this handy feature, so we’ll give you a quick breakdown. When looking at the video player, you’ll notice there are three specific areas.
The green area reduces play speed, red makes videos play at half the normal rate, and yellow speeds up the playback speed. Just move the slider to whatever position you want. You can always revert to the normal playback speed later on. Your experience may vary, depending on what version of iOS you’re using.
