  Audio Drift when sync double system audio

  Posted by Uli Kunkel on June 21, 2008 at 8:31 am

  I’m currently in the process of syncing dailies for a feature that is currently in production. The film is being shot on the Red camera at 23.98 fps Non-drop. The audio is being recorded on an Aaton hard drive recorder in broadcast wave 23.98 fps non-drop at 48.048kHz 24-bit.

  When I merge the audio and video in FCP, the audio starts in sync and begins to drift rather quickly. At first I thought that FCP wasn’t slowing the audio files down to play back properly at 48kHz, so I tried converting them in Compressor to 48.000 kHz. That only made it worse.

  Any ideas as to what I might be doing wrong here?

  Thanks.
