This one is a keeper. Improved my video editing time enormously. Great overlay option adds ability to create personal watermarks as well if you make your own logo. If it is to difficult in the app, other apps like Union, ArtStudio and Photowizard can help you make a mask (.png). However, this app saves you time if you can master masking inside the app and is satisfactory to the point where I dont need another app to make a mask.
