In a video encoding method, a to-be-encoded video is obtained. The video includes at least two video frames arranged in sequence. A quantization parameter and a quantization parameter threshold of an ivideo frame is calculated, where i is a positive integer greater than or equal to 2. A coding resolution of the ivideo frame is determined according to the quantization parameter and the quantization parameter threshold. The coding resolution is a first coding resolution in a case that the ivideo frame is sampled, and the coding resolution is a second coding resolution in a case that the ivideo frame is downsampled. Then the ivideo frame is encoded at the coding resolution.
