A method and system are described for low-latency video. In the method a frame, selected from a group of frames, is divided into P-regions and an I-region based on an assigned refresh pattern in a refresh loop. An I-region bit budget and a P-region bit budget are determined. Quantization parameters are determined using the I-region bit budget and the P-region bit budget. Macroblocks of the selected frame are encoded based on the quantization parameters. The I-complexity and P-complexity are updated and a new frame bit budget is determined. The dividing, determining of the I-region bit budget, determining of the P-region bit budget, determining of quantization parameters and encoding are repeated for each remaining frame in the group of frames.
