Digital video effect
Digital Video Effects, commonly called DVEs, are visual effects that provide comprehensive video image manipulation, in the same form as optical printer effects in film. DVEs differ from standard video switcher effects such as wipes or dissolves, in that they deal primarily with resizing, distortion or movement of the image. Modern video switchers often contain internal DVE functionality.
Early examples of DVE devices found in the broadcast post-production industry include the Ampex ADO, Quantel DPE-5000, Vital Squeezoom, NEC DVE and Abekas A-51.
DVEs are used by the broadcast television industry in live television production environments like television studios and outside broadcasts. They are commonly used in video post-production.
