There are three different ways to add an image to a video
To upload a logo, select Logos and click Upload Media
To upload an image that you want to use as a background or overlay, select Upload and then click Upload Media
To add an image from our stock library, select Stock and then search an image that you want to use
Once you've selected an image that you want to use as a logo or overlay, drag it into your project, or select the small + icon to add it into your project.
Once your image overlay is added, you can :
