Add your own music/audio to a video
This app was just what I was looking for to add music from my iTunes library to an Instagram video. The app is dead simple to use, enabling you to trim your video to a custom length or a 15-second Instagram video length, then select audio to go over it. You can choose the audio start point and whether you want it to fade in/out. You can mix your audio/music with the original videos audio anyway you wish. You then preview the video before export (which is SUPER fast on my 5S). If you decide to tweak your audio or video once you preview your result, its as simple as hitting the Back button in the app to get things right. Once youre done you can export to your Camera Roll, Instagram, Facebook, or email.
Great app. Nice work, developers!
