Prepping For A Mix Session

  • Always include all available channels of audio!
  • You may desire to mute one track or the other for your rough cut presentation, but please do not delete them from your sequence.
  • If it was shot with a Lav & a Boom then include both. We never know what will be useful in the mix…
  • All audio files should be at the same sample rate to insure accurate playback.
  • Replace any lo res MP3ʼs in the edit, such as temp music,with full res AIFF or WAV versions.
  • If youʼve rendered any audio effects (such as EQ for a phone voice) also include the original audio source on a muted track.
  • Roomtone is your friend! Send us as much as you have, at the end of your sequence.
  • If you have any questions at all about how to prep or what to expect from us, please don’t hesitate to call us!

What we need from you for your Mix Session

  • An OMF (Type 2) or AAF export from the edit sequence
  • Embedded media, with 90 frame (or more) handles
  • A Quicktime movie that matches the OMF framerate with audio from the sequence
  • Match the start of the OMF at 59:58:00 EXACTLY
  • Include a visual reference to the 2POP
  • Please call us with any questions you might have about how to prepare your session for a mix.

What is a 2Pop?

A 2POP is a 1kHz sine wave, two frames long,  at -20dB placed exactly 2 seconds before the first frame of picture.  Usually this occurs at 00:59:58:00, or 2 seconds before hour 1. Many editors will also include color bars to give a visual reference as well.  Basically, it’s a beep. However, it can be a very important beep.  When dealing with lip sync issues that can occasionally occur when passing a session back and forth between editorial and audio post, if there is a 2Pop in place, the troubleshooting is improved greatly.
