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 (often referred to as "analog effects") such as wipes or dissolves, in that they deal primarily with resizing, distortion or movement of the image.
Early examples of DVE devices found in the broadcast post-production industry include the Ampex ADO ("Ampex Digital Optics"), Quantel DPE-5000, Vital Squeezoom, NEC DVE and Abekas A-53D. Modern video switchers often contain internal DVE functionality.
