Abstract
Aspects of the disclosure provide methods and apparatuses for video processing. In some examples, an apparatus for video processing includes processing circuitry. The processing circuitry determines one or more parameters of a temporal filter based on video contents in an uncompressed video. The uncompressed video includes a sequence of frames. Then, the processing circuitry applies the temporal filter with the determined parameter on a first pixel in a first frame to determine a filtered value for the first pixel based on the first pixel in the first frame and second pixels in a group of reference frames for the first frame. Further, the processing circuitry encodes a filtered video that includes the filtered value for the first pixel in the first frame to generate a coded video bitstream that carries the filtered video.
