iOS Pick: LumaFusion
Leo Laporte's app cap on iOS Today 350 is LumaFusion from LumaTouch. This a powerful multi-track video editor that gives you 3 video/audio tracks for photos, videos, titles, and graphics, and 3 additional audio tracks for narraction, music, and sound effects.
When you create a new project, you can choose your frame rate, which goes up to 60 frames per second. Then you can select either a square or film aspect ratio. Then you can drag videos in from your iCloud Photo Library, or import media files stored in Box, Dropbox, Google Drive, and OneDrive.
LumaFusion has all of the basic editing features you'd expect, such as trim, duplicate clip, split clip, and delete, and it has dozens of transitions available. It even has more sophisticated effects that can be layered. You can add blurs, pixel effects, and color distortion. It has full color correction, the ability to add keyframes for animation, and you can add unlimited keyframes for animation. You can also copy and paste those effects and attributes between clips. The included titler lets you adjust font, color, face, border, and shadow, and you can create multi-layer titles with text, shapes, and images.
When you're done, you can easily share your video to the Photos app, Facebook, YouTube, Vimeo, Box, Dropbox, Google Drive, OneDrive, or use Airdrop to send it to your Mac. It supports a variety of resolutions and qualities up to 4K.
