you have to explain what you want/mean.
You need a video from some talking face (who ?) or you need to create a DFM from your head or somebody else ?
if the DFM is available, there is almost no work, but in other case, creating a DFM is a huge work, because you need to find
tons of pictures of the subject, then process several days on computer with nice specifications (Rtx3090 or 4090 welcome).
