Masking with PNG Images: Select your video clip, scroll down to the Track Mattes panel settings, click Mask, choose your PNG image (like a logo or character), and set the channel to Alpha to seamlessly play the video within that graphic.
Creating Dynamic Transitions: Animate a shape (such as a circle scaling up to fill the screen) and set your video clip's track matte to that shape using the Alpha channel to reveal your video via a smooth transition effect.
Advanced Text Reveals: Apply an Inverted Alpha track matte to a background shape or layer targeted at an animated text element to create complex typography reveal effects where your video transitions into text.
