Slow Fast Slow is a free iPhone app to adjust video playback speed within few minutes. The app lets you adjust video playback speed of any portion of the video as per choice. You can make anything look faster and slower in any of your videos stored on your iPhone. The app also lets you trim videos in case you are interested in only a specific part of any video.
The app even supports reverse playback of video, adjust the speed, and then save them to share with anyone you like. All the videos get saved to your iPhone’s photo album. The other cool feature of the app is it retains the actual audio pitch even if the portion of the video is turned faster to slower.
As per the app’s description, the app lets you slow down 24fps videos to 1/16 of their actual speed. It is available for iPhone 6 and iPhone 6 Plus.
