Method for video processing, electronic device, and storage medium

An electronic device, comprising:

• a processor;
• and
• a memory for storing instructions that, when executed by the processor, cause the processor to:
• determine a target frame in a video to be processed;
• determine at least two first energy images corresponding to the target frame based on at least two preset macro block sizes, respectively, each of the first energy images representing alternating current energy of at least one first macro block corresponding to a respective one of the macro block sizes, wherein the at least one first macro block is obtained by segmenting the target frame based on the respective macro block size;
• determine a first energy map corresponding to the target frame based on the first energy images, wherein the first energy map represents energy distribution in the target frame;
• and
• determine, based on the first energy map, an adaptive quantization parameter corresponding to the target frame and encode the target frame by using the adaptive quantization parameter.

A non-transitory computer-readable storage medium having stored thereon computer program instructions that, when executed by a processor, cause the processor to perform the following operations including:

• determining a target frame in a video to be processed;
• respectively determining at least two first energy images corresponding to the target frame based on at least two preset macro block sizes, each of the first energy images representing alternating current energy of at least one first macro block corresponding to a respective one of the macro block sizes, wherein the at least one first macro block is obtained by segmenting the target frame based on the respective macro block size;
• determining a first energy map corresponding to the target frame based on the first energy images, wherein the first energy map represents energy distribution in the target frame;
• and
• determining, based on the first energy map, an adaptive quantization parameter corresponding to the target frame and encoding the target frame by using the adaptive quantization parameter.
