Abstract: By one approach a control circuit receives video information to be encoded, uses a particular rounding control value when processing the video information, and detects when color banding occurs when processing the video information using the particular rounding control value and responsively reprocesses the video information using a different rounding control value. By another approach, the control circuit has a plurality of different intra prediction types, including a planar intra prediction type, available to use when encoding the video information and wherein the control circuit determines when the planar intra prediction type can be employed without testing use of all of the plurality of different intra prediction types. By yet another approach, the control circuit selects block coding parameters, at least in part, by comparing corresponding mode costs, detects a smooth area in the video information, and then modifies mode costs as a function of having detected the smooth area.

Abstract: There is provided a computerized method and system of optimized video encoding of an input video sequence corresponding to a plurality of input frames, the method comprising: obtaining an input frame; performing a first encoding of the input frame using a first encoding parameter determined in accordance with a target bit-rate, giving rise to a first encoded frame; performing a second encoding of the input frame using an iterative quality-driven encoding scheme initialized with an initial second encoding parameter, the initial second encoding parameter determined based on the first encoding parameter, the second encoding performed in an attempt to seek a second encoded frame having a lower bit-rate than the first encoded frame and meeting a quality criterion relative to the first encoded frame; and in case of the second encoded frame being found, providing the second encoded frame as an output frame corresponding to the input frame.
