The number 77 is used in multiple places within this block. To improve readability and maintainability, it's good practice to define it as a variable before this block and reuse it. This avoids 'magic numbers' and makes it easier to change this value in the future. For example:

num_frames_to_process = 77
animate_pose_video = VideoData(...).raw_data()[:num_frames_to_process]
animate_face_video = VideoData(...).raw_data()[:num_frames_to_process]
