Abstract
The invention concerns a method of video encoding comprising: determining a first ratio (IP) based on previously encoded picture frames of a video sequence comprising one or more intra-coded pictures (I) and one or more predicted pictures (P), the first ratio (IP) being calculated based on the ratio between the size of one or more previously encoded intra-coded pictures and the size of one or more previously encoded predicted pictures; and determining a quantization parameter (QP) to be applied to a frame to be encoded based on the first ratio (IP).
