    Abstract: Methods, apparatus, systems and articles of manufacture to adjust intra-frame encoding distortion metrics for video encoding are disclosed. Some example methods for video encoding disclosed herein include obtaining an intra-frame encoding distortion metric representative of distortion associated with a first intra-frame encoding mode for encoding a pixel block in a frame of a video sequence. Some such example methods also include adjusting the intra-frame encoding distortion metric based on a characteristic associated with the pixel block to determine an adjusted intra-frame encoding distortion metric. Some such example methods further include comparing the adjusted intra-frame encoding distortion metric with an inter-frame encoding distortion metric representative of distortion associated with a first inter-frame encoding mode for encoding the pixel block to determine whether to use at least one of the first intra-frame encoding mode or the first inter-frame encoding mode to encode the pixel block.

    Abstract: Techniques related to video coding include content adaptive quantization that provides a selection between objective quality and subjective quality delta QP offsets. An adaptive method generates an objective quality delta QP offset that achieves a best peak signal-to-noise ratio (PSNR) and/or structural similarity (SSIM) score, which refers to a similarity between images. Also, the adaptive method generates a subjective quality delta QP offset that achieves the best video multi-method assessment fusion (VMAF) score and/or multi-scale structural similarity (MSSIM) score.

    Abstract: Methods, apparatus, systems and articles of manufacture to perform quantization offset and/or cost factor modification for video encoding are disclosed. Some example methods for video encoding disclosed herein include adjusting a quantization offset to quantize a transform coefficient representative of a pixel block in a frame of a video sequence. For example, the quantization offset can be adjusted based on a quantization parameter obtained to quantize the transform coefficient. Some such example methods also include quantizing the transform coefficient according to the quantization parameter and the quantization offset. Some example methods for video encoding disclosed herein additionally or alternatively include adjusting a cost factor based on a characteristic of a pixel block in a frame of a video sequence. Some such example methods also include determining, based on the cost factor, a cost associated with encoding the pixel block according to a first encoding mode.
