After adding an image layer to the canvas, a variety of tools will appear at the top of the screen, including AI Tools, Filters, Flip, Crop, Opacity, Animation, Inside Motion, and more.
You can use these features to fine-tune your image layer and make it perfectly match your background scene.
You can also right-click on the image layer on the canvas to access additional options, such as Copy & Paste, Delete, and Set as Background.
