Video encoding method, apparatus, and device, and storage medium

A video encoding method of a video encoding apparatus is provided. In the method, an intra-frame pre-coding cost of a video frame is calculated. The intra-frame pre-coding cost indicates an amount of information in the video frame and a spatial correlation degree of the information in a plurality of code blocks of the video frame. A quantization parameter threshold of the video frame is set according to the intra-frame pre-coding cost. A quantization parameter estimation value of the video frame is calculated. The quantization parameter estimation value indicates a predicted compression status of the information in the video frame. A target encoding manner of the video frame is determined according to the quantization parameter threshold and the quantization parameter estimation value. The target encoding manner is one of a plurality of encoding manners including full-resolution encoding and downsampling encoding.
