description Computing encoding parameters for an encoding video using constant rate factor control for a multi-layer coding scheme. This includes receiving an encoding quality factor 110 indicating a desired visual quality for an encoding of the input video. The encoding quality factor is mapped to a base quality factor 115 indicating a desired visual quality for a base encoding of the input video, the base encoding providing an encoding at a first level of quality. Base encoding parameters 130 are obtained from a base encoder 125. The encoding quality factor, base quality factor, and base encoding parameters are mapped to enhancement encoding parameters 140 for an enhancement encoding, where in a combination of the base encoding and the enhancement encoding provide an encoding at a second level of quality that is higher than the first level of quality. In embodiments the multi-layer video standard is Low-Complexity Enhancement Video Coding (LCEVC).
