This application provides techniques of processing video frames. The techniques comprise obtaining a target frame of a video; capturing at least one to-be-processed image from the target frame, wherein the at least one to-be-processed image comprises at least one segment of the target frame; generating a plurality of channels by performing channel decomposition on the to-be-processed image, wherein the plurality of channels comprise a first channel and a second channel; embedding watermark information indicative of a watermark into the first channel; embedding location information into the second channel, wherein the location information indicates a location of the watermark in the target frame; generating a target image corresponding to the to-be-processed image based on the first channel comprising the embedded watermark information and the second channel comprising the embedded location information; and generating a watermarked video by embedding the target image into the target frame.
