I stumbled upon this by chance because I needed a decent chroma key app for on-the-go video art. This app is a DREAM. I am giving 5 stars because this app needs love and it’s the only one in the App Store that does what it does so well. It does have some places it can improve but, you know, later version or something. I’m patient. What’s to love: HD export! Perfect. Work area is touch friendly. Three layers for video/images. Projects can be saved and loaded later. Chroma Key can be adjusted to any color/sensitivity. Interface is simple enough to use. Final result looks fantastic! (This depends on your source footage, of course) Fast! Relatively stable. What could use work: More adjustments for chroma key - edge blur maybe? Keyframes! I love how I can positing things in the editing window via touch. It would be even cooler if those things could change positions over the course of the video. With three layers, you could do a great parallax effect. A couple more editing buttons? Or at least a “split clip” option - “trim” only goes one way. Support for aspect ratios other than 16:9 On the whole, this is my favorite chroma key app on this platform. Definitely worth a try.
