def reference(
  name: str = None,
  id: str = None
)

A sieve.reference is a reference to a sieve.function or sieve.Model that has already been deployed by you or another user. The power of sieve.reference is that it allows you to use a sieve.function or sieve.Model that has already been deployed without having to re-deploy it. For example, you might choose to use a “video splitter” utility already deployed at sieve-developer/video-splitter.

def wav2lip(video: sieve.Video, audio: sieve.Audio):
    images = sieve.reference("sieve-developer/video-splitter")(video)
    faces = sieve.reference("sieve-developer/mediapipe-face-detector")(images)
    tracked_faces = sieve.reference("sieve-developer/sort")(faces)
    return Wav2Lip()(video, audio, tracked_faces)
