AutoYUY2 Description

Traditional YV12 to YUY2 upsamplers operate either in the progressive or interlaced mode, and the upsampler must be told which mode to use. This paradigm can be unsatisfactory in several cases: - The user is unsure of, or unable to determine, which mode to use. - Segments of a clip are sampled progressively, while others are sampled interlaced. - There are frames which have areas sampled progressively, while others are sampled interlaced. Commonly encountered instances are field blending conversions and 3:2 pulldown of progressively sampled video. The former results in parts of frames being effectively interlaced, while the latter results in a mixture of progressive and interlaced frames. Use of a traditional upsampler in these cases will result in the wrong upsampling being performed on some frames or frame areas. The result will be the chroma upsampling error (CUE) if a progressively sampled area is upsampled interlaced, or destruction of interlacing (DOI) if an interlaced area is upsampled progressively. The AutoYUY2 Plugin for Avisynth filter was designed to avoid these problems by detecting interlaced frame areas and then applying either progressive or interlaced upsampling as required.
