Spot Mixing
Video Mixing is to combine video signals from two or more sources. Synchronized inputs are mixed with each other and various special effects patterns and shapes are added in accordance with the proficiency of the video mixer being used. Two pictures can be superimposed; one on the other, while a third picture is cut into a “hole” in the scene. A video mixer usually generates sync *signals allowing genlocking* of additional video sources to the first source. Video mixing is done nowadays digitally with digitized analog or native digital sources.
