If there’s no clip or blank frame placed on the timeline to match the music at the end of your project, this part won’t be included in the downloaded file. To make sure it’s included, add a Blank Frame to the end of your project:
- On the timeline, place the playhead(yellow vertical line) at the point where your last clip ends.
- Tap on Media from the main toolbar > select Blank: a blank frame will be added to your timeline
- On the timeline, tap on the blank frame to change its Color and Background
- To change the length of the blank frame, tap on its white side handle and drag right/left
You should now be able to save your entire project successfully.
