Simple way to speed up previously shot video – Slow Fast Slow - Control the Speed of Your Videos Review

I was looking for an app that would speed up my videos to fit in parameters of a social media app. Many other free apps require you to shoot the video in their app. This one allows you to upload from your camera roll and edit, then save the new version to your camera roll. It even saves video square uncropped. It took me literally 30 seconds to figure it out and edit my video. Easy to use.
