  Prores 422 Audio Render issues

  Posted by Ian Durkee on February 25, 2011 at 4:38 pm

  First, thanks for being a fantastic resource.

  When I bring prores 422 (not HQ) clips into a sequence in FCP 6 I have to manually render the audio each time. What could I be doing wrong?

  Is your audio 48k? Aif or Wav?

  I believe it is AAC. I took some H264 footage and applied the prores 422 settings in compressor before bringing it in to FCP.

  In the Browser it will give you the specs on the audio.
  You probably need to re-do em so they are 48k, 16bit, aif’s

  Then there will be no audio issues for you.

  I’m assuming that these ProRes Clips were pushed through compressor – the compressor preset for transcoding does pass through audio – leaving you with AAC audio. You’ll have to redo them with Linear PCM, 16 bit, stereo for FCP to work with them in RT.

  Best,

  What was your original file format from your camera?

  I have a headcam which produces H464 video files, the audio is recorded at 16Khz.

  Playing the unconverted camera clip in QT and select the show window>movie inspector will tell you.

  As stated above compressor by default does nothing to the audio when converting to ProRes, you need to set the converted audio to 48KHz.
