The QP for a frame may be derived by determining an initial QP, adapting this value, and applying a final control calculation. The QP for a frame may be calculated from a variety of variables, that may include the frame type (intracoded (I), predictive (P), or bipredictive (B)), the fullness of a hypothetical reference decoder (HRD) buffer, the instant and target bit rates, a total encode size, a total target size, the number of P frames between I frames in a group of pictures (GOP), the number of B frames between I frames in the GOP, and the size of previous frames."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for frame level bit rate control without pre-analysis","description":"Methods and systems to determine a quantization parameter (QP) that may then be used in a bit rate control process during video compression and decompression.
