The BCC Video Morph filter performs a combined warp and dissolve blend from one video clip into another clip, resulting in the generation of an animated image morph. The filter uses matched pairs of user generated Adobe After Effects spline mask shapes to define edges on the source and the corresponding destination clips at key points along the timeline.
For example, when morphing a face from one video clip into a different face in a second video clip, the user creates and animates matched pairs of open or closed spline shapes on the source image clip that follow the contour line of key elements in the source and destination images, such as the jaw line, eyes, ears etc and the filter uses these shapes to aid in generating a smooth morph transition between the two clips.
While it is creating the image warp, the filter also generates a blend over time between the source and destination clips. In addition to the AE spline mask shapes, which the filter uses to define the warp, the filter also uses Key Markers, which serve as instruction points for the Morph filter’s software algorithms that are set in the filter control panel by the user for the source and destination images to control of the duration of the morph. The Key Markers function is to instruct the filter on when to start and stop the image morph.
