Slow Fast Slow is an app for manipulating the speed of videos you shoot on your iPhone. It works especially well with slo-mo videos. Use the intuitive interactive timeline to slow down or speed up your videos. Additionally, you can add pitch control, as well as clip reversal.
• Import videos from your Photo Library.
• 240 fps videos (iPhone 6 and 6 Plus) can be slowed down to 1/16 speed, which is twice as slow as the built in camera app.
• Pitch Control: Retain the correct audio pitch even when the video is sped up or slowed down.
• Backwards playback.
• Add and remove points to adjust the timeline.
• Export videos in the original ratio or square.
• Requires iOS 10.
Feature placements are determined by the app stores and help users to discover new and popular apps. Knowing when and where an app is being Featured can explain a sudden boost in popularity and downloads. App Annie tracks all the different Feature placements for any app, day, country, category and device.
Also featured in 13 other countries, and probably even more in the past.
App stopped recognizing new videos I’d shot and wanted to slow down. Kind useless now.
