Abstract: A method that is performed by a video encoding device is provided. The method includes identifying N image frames in a sliding window of an image frame sequence, the N image frames including N−1 encoded image frames and a to-be-encoded image frame; obtaining a motion amplitude difference of the N image frames in the sliding window, the motion amplitude difference indicating a difference between a corresponding image frame motion amplitude and a previous image frame motion amplitude; updating a static variable based on the motion amplitude difference of each of the N image frames in the sliding window, the static variable indicating a number of consecutive static image frames; and encoding the to-be-encoded image frame as an I frame based on the updated static variable not being less than a first preset threshold.

Abstract: A video encoding method is provided. The video encoding method includes: obtaining a to-be-coded video frame; determining a current encoding mode according to current coding information and/or image feature information of the to-be-coded video frame; processing the to-be-coded video frame according to the current encoding mode to generate a current coded video frame; obtaining a current reference frame corresponding to the current coded video frame based on the current coded video frame being an inter frame; obtaining a corresponding processing reference frame according to resolution values of the current reference frame and the current coded video frame; and encoding the current coded video frame according to the processing reference frame to generate first coded data.
