Options include: None ­ Performs no de-interlacing of any kind. Auto ­ Applies inverse telecine de-interlacing to all telecine video. ­ Applies motion adaptive de-interlacing to all video that is not telecine. ­ Switches dynamically between the two modes as the content changes. Inverse Telecine ­ Drops the redundant fields and reassembles the video in a 24 fps progressive format. ­ Applies inverse telecine de-interlacing to all telecine video. ­ Performs no de-interlacing of video that is not telecine. ­Available for NTSC video only. ViewCast 46 Niagara 7500 User Guide Step Action Motion Adaptive ­ Is an algorithm for de-interlacing pure video (non-telecine) content. ­ Applies motion adaptive interlacing to all video. It detects which portions of the image are still and which portions are in motion then applies different processing to each scenario.

This value is the quantizer scale offset between I-P-B-frames. The encoder normally encodes all 3 color planes (luma, U (chroma), V (chroma) ) at the same quantizer. The system adds this value to the quantizers for the U and V planes. [. . . ]
