Abstract
Disclosed are a video frame coding method performed at a terminal. The method includes: obtaining and coding an ith video frame in a group of pictures, and counting a quantity of actually consumed bits corresponding to the ith video frame; detecting a state of the ith video frame based on the quantity of actually consumed bits, an initial average bit rate of the group of pictures, a quantization model, and a video frame detection rule, and determining multiple quantization parameters of a (i+1)th video frame; and determining first quantities of allocated bits for compensation of first to-be-compensated video frames; updating the first coding rule according to a first quantity of allocated bits for compensation, the quantization parameters corresponding to the (i+1)th video frame, and coding the (i+1)th video frame.
