Adaptive multi-pass risk-based video encoding

Abstract:

Devices and methods are provided for adaptive multi-pass risk-based video encoding. A device may receive a segment of video frames encoded using first encoding parameters. The device may determine a group of pixels in a first video frame of the video frames. The device may determine characteristics associated with the group of pixels and may determine, based on the characteristics and a number of pixels in the group of pixels, a score associated with the segment, wherein the score is indicative of a visibility of banding compression artifact. The device may determine, based on the score, second encoding parameters associated with encoding the segment.
