you import the video. When you are ready to import your video on the right of your screen there is a box with a arrow facing down. Press on it. Then press Export.
You can try screen recording the video. Uninstall the app then download it again. (If your using pro or lite maybe use a the other one if you have both of them). The best I can help you with. Also keep in mind not all templates work the same in some device's (I tried in different devices they are either moved or just different then expected). :)
