1.
Mask the background of your CrazyTalk model.
2. In timeline view of your CrazyTalk script, double-click on the "SFX-Swap" line where you want your custom background to appear. Click the "A_Full"
special effect template from the "Image Overlay" tab "Full Screen" theme. Then click on "Modify" (top center) and "Import" your custom background.
3. Make sure the image is in the background by
swapping the special effect.
4. Repeat for more custom backgrounds. You can drag and move the special effect on the timeline and drag its left or right edges to adjust the length.
