It is unprofessional for Ps to make dynamic pictures, so it is necessary to decompose the dynamic pictures into several frames and then process them frame by frame. If you stick your face on the pig's head, you should first adjust the size of the face to be similar to that of the pig's face, then rub it on the pig's face with a stamp-imitating tool, then adjust the color to make it more complete, and finally introduce IR to make it dynamic!
