Layer events composite two events. They can also create a transition from one event to the event that follows. The topics in this section describe the layer events that are provided with Video Post.

Layer Events
Topics in this section
- Alpha Compositor
The Alpha compositor composites the two images using the alpha channel of the foreground image. The background image appears in areas where the foreground image's alpha channel is transparent. - Cross Fade Compositor
The Cross Fade compositor composites the two images over time, cross-fading from the background image to the foreground image. The rate of the cross fade is determined by the length of the Cross Fade Transition filter's time range. - Pseudo Alpha Compositor
The Pseudo-Alpha compositor composites a foreground image against the background by creating an alpha channel for the foreground image based on the foreground image's upper-left-corner pixel. All pixels in the foreground image that use this color become transparent. - Simple Additive Compositor
The Simple Additive compositor composites the two images using the second image's intensity (HSV value) to determine transparency. Areas of full intensity (255) are opaque; areas of zero intensity are transparent; and areas with intermediate transparency are translucent. - Simple Wipe Compositor
The Simple Wipe compositor reveals or erases the foreground image with a wipe transition. Unlike the Wipe filter, the Wipe layer event moves the image, sliding it in or out.
