LatentSync (Apache-2.0) and MuseTalk (MIT) are now first-class presenter
engines and come before wav2lip for a clip, so the compose documentation says
which engine engine:"auto" will pick and why: wav2lip works at 96x96 and
upscales, which is where the soft mouth on a 1080p reel comes from, while
these two run at 256-512 px natively. sadtalker still leads for a still
portrait because it is the only one that invents head motion rather than
replacing a mouth.
