The application provides a training method of an action trajectory generation model, an action trajectory generation method and device. Action category feature extraction and action trajectory feature extraction are performed on a first action trajectory sample to obtain an action category feature vector and an action trajectory feature vector. Action trajectory prediction is performed based on the action category feature vector and the preprocessed action trajectory feature vector to obtain a first prediction feature vector, so that the first prediction feature vector is obtained based on the two dimensions of the action trajectory category and the action trajectory itself. The model parameters are iteratively updated based on the action category recognition result and the action trajectory discrimination result of the first prediction feature vector. The predicted action trajectory is not required to be consistent with the action trajectory sample, but only the action category loss and the action trajectory authenticity loss are considered to optimize the model parameters, so that the authenticity, controllability and action style diversity of the action trajectory output by the trained model can be ensured.

This application relates to the field of digital human technology, providing a method, apparatus, device, medium, and product for generating digital human video ringback tones. The method includes: determining a reference video based on reference audio; obtaining the motion trajectory of a reference figure in the reference video; filtering target videos from a video library based on the motion trajectory of the reference figure; determining at least one keyword in the lyrics of the reference audio; filtering each video in the video library based on the keyword to obtain motion change information of the figure in the video frame corresponding to the keyword; determining the motion trajectory of the digital human based on the motion change information; and merging the reference audio, target video, and digital human into a digital human video ringback tone. This allows for the combination of reference audio and target video, and through the motion performance of the digital human, makes the final generated digital human video ringback tone more interesting and attractive, providing users with a more personalized and innovative calling experience.
