UE 5.3's Live Link Face guide says the iOS app streams ARKit facial animation to Unreal over the network (not USB); each recording saves a .mov reference video (JPEG-compressed frames, audio, timecode) and a .csv of raw ARKit curves importable via the Beta LiveLinkFaceImporter plugin into a Level Sequence; timecode comes from the system timer, an NTP server (default time.apple.com) or Tentacle Sync, and the app accepts OSC remote control.
