  changing audio bit depth

  Posted by Michael Sullivan on January 28, 2013 at 8:39 pm

  Howdy,

  I have a project with a massive amount of clips. Most have been captured at 24bits, and some at 16.

  When these are mixed in a timeline, the audio is a little out of sync and I believe this is the reason.

  Does anyone know if it’s possible for me to change the bit depth within FCP or anywhere else without changing the video information in said clip?

  If it was just a few clips I would recapture, but we’re talking a lot of clips.

  Thanks!
  Mike

  Thanks for your reply,

  These clips are actually finished commercials for historical reel. Most of the spots are

  Mac 10.6.8
  2.2.26 GHz Quad-Core Intel Xeon
  16GB Memory

  FCP 7.0.3

  The source clips are standard def NTSC CCIR601
  Uncompressed 10bit 4 2 2
  720×486 29.97
  48kz
  and then some are 16bit and some are 24bit

  There also are some Pro Res 422HQ mixed in there as well, though not too much.

  SEQUENCE SETTINGS

  720×486 CCIR 601 NTSC (40:27)
  PAR 720×480 DV
  Field Dominance Lower(Even)
  Editing Timebase 29.97
  Compressor Apple ProRes 422HQ
  Audio Rate 48
  Audio Depth 16
  Config Stereo Downmix

  You’re right in my assumption that it was the bit depths, but I guess it could be something else as well.

  I have a KONA capture card and I’m judging sync on my computer monitors, not my video monitor.

  Do you need any other info?

  Judging sync? Are you saying that that the viewers in FCP aren’t accurate?
