Abstract: Aspects of the disclosure are directed to a media content placement method and a related apparatus. According to the method, a target video and first media content can be obtained, and video frames of the target video are inputted into a first model for corner tracking to obtain a plurality of target corners. Additionally, a target region in the video frames can be determined according to the target corners, and the first media content can then be placed into the target region. In this way, the automatic placement of the media content is realized. The target region in the video frames can be determined through the target corners outputted by the first model, thereby ensuring the accuracy of the placement process. In addition, the whole process does not require manual replacement, which improves the efficiency of media content placement.
