single stream: subtract an int from each pixel (Darkness) dual stream: subtract stream 2 from stream 1


single stream: subtract an int from each pixel (Darkness) dual stream: subtract stream 2 from stream 1 In single stream mode, v.- subtracts an int or float from each pixel in the video stream. For yuv images, v.- subtracts the integer only from the y (brightness) component. Streams with int16, int32 and float32 components are processed in their existing component sizes. In dual stream mode, v.- subtracts each pixel in stream 2 from the corresponding pixel in stream 1. If the first stream is int8 then the second stream is forced to int8 as well. If the first stream is float32 then the second stream is forced to float32. When signed output is chosen, the brightness of the output stream is expressed in an unusual way for easier display and processing, with middle gray (128) representing no difference. -128 is represented as 0, 0 is represented as 128 and 128 is represented as 255.
