An overlay is one of the ways you can combine objects, such as photos and videos, with other objects so that they appear in the same frame. You have several options for using overlays. It combines two or more images or videos, editing green screen videos, adding a logo or sticker, or adding text captions to videos.
Open the Overlays menu at the bottom of the screen and tap Add overlay. Click on the text, logo, or image you saved earlier and add it to the overlay. Then, click the Splice button. Select your overlay type and adjust the opacity.
