Abstract
A system for providing improved video quality and compression efficiency during encoding by detecting video segments having film grain approaching the 'Red Lady' problem. The system detects when film grain approaches the level of the 'Red Lady' problem by measuring frame-by-frame temporal differences (ME scores). From the ME scores, two key indicators are identified: (1) The average temporal difference in frames with an intermediate motion level higher than frames of non-noisy video; and (2) The fluctuation of the temporal differences between frames in a group is very small. When these indicators identify a high film video, a signal is provided to an encoder which allocates less bits to I frames and more bits to P and B frames than for other frames of video without comparable film grain.
