Video Star and VideoFX Live can be used while holding your device in either landscape or portrait mode. To use in landscape, just rotate your device. If the app doesn’t rotate, swipe up and unlock the rotation lock. Now you’ll be able to use your device in either the portrait or landscape mode. To lock the app in landscape mode, tap this gear button on the main screen. Tap Lock in Landscape. Now when you rotate your device or lock the rotation lock in the control center, the app will always be in landscape. One otherthing to remember: When you are filming a portrait video, you will want to hold your phone in portrait; otherwise the video will be zoomed in. This is also true when filming landscape video in portrait mode.
