Note: this functionality works best when there is a person or animal to mask / cut out.
Step 2. Tap Layout, and tap the Mask button – little avatar icon on the main video screen. Tap the tick to save.
Step 3. Tap Text to add your text.
Step 4. Before you save your text, tap the Mask button again and the text will move behind you.
