Abstract
This disclosure is directed to systems and methods of rate control in multiple pass video encoding. The video encoder may complete multiple encoding passes for slices of an image. Rate control algorithms may be implemented that scale the quantization step size and quantization matrix values depending on the determined size of the image slices. This may enable the size of slices to be adjusted based on size parameters for the image data.
