  DV 24p questions….

  Posted by Ewoo Oowe on September 12, 2007 at 2:36 pm

  I have a sequence with DV 24p Advanced footage in it.

  I need to make a digibeta master for a festival screening.

  Prior to this the sound will be mixed in Pro-Tools by a mixer / designer.

  I need to provide the mixer with an OMF and a quicktime of the movie with timecode burnt in.

  He will mix the sound and then provide AIFF files for me to sync back to the picture before output to digibeta.

  The editing timebase of my FCP sequence says “23.98”. The TC rate of my clips is “30”.

  I presume that the Pro-Tools work will need to happen in 29.97 so that the sound will go back to digibeta correctly (digibeta being a 29.97 format only).

  Do I need to put my sound into a 29.97 sequence prior to making the OMF?

  Do I need to put my picture into a 29.97 sequence prior to making the quicktime with burnt in timecode for the mixer?

  When I receive the audio back should I put it into a duplicate of the original sequence (editing timebase (23.98) or into a 29.97 sequence?

  I think I understand most aspects of DV 24p (it is actually on 29.97 but then certain frames are thrown away on playback to achieve 24p). However this sound process has left me a little uncertain as to what to do.

  Thanks in advance,

  Hi Dave,

  Thanks for the response.

  1. Yes….the audio mixer can deal with 23.98 or 29.97.

  2. I didn’t do the original capturing, but when I get the information on the clips, it says ‘TC Rate 30’. However the sequence was edited in a 23.98 timeline. Playback looks fine on both computer and video monitors.

  I believe the video clips still have all the information (all 29.97 frames), but that FCP is removing them on the fly for playback. At least that is my understanding.

  Can you enlighten me any further on the correct workflow given this information?

  Thanks again,

  Ewoo

  Hey,

  Thanks for responding……

  But I’m still not sure what I should be doing…..

  I need to provide the audio mixer with an OMF and quicktime (I know how to make these but need to know what frame rates and settings my sequences should be set to).

  When I get the audio back I need to match it to picture and put it on Digibeta (through SDI with a KONA).

  The footage was shot 24p Advanced and edited in a 23.98 timeline. When I check the info on the clips in FCP it says TC rate 30fps. However when I open the clips in quicktime and check the info it says 23.98fps. I am presuming that quicktime is able to understand the pulldown and interpret the clips as 23.98, even though they really still exist as 29.97?

  Thanks….

  Ewoo
