  Mixing 23.98 & 29.97 Workflow

  Posted by Paul Turlick on November 22, 2005 at 6:40 pm

  Hi-

  I’m working on a HDCAM doc and have a bunch of footage in the can shot in 1080i @ 29.97. I’m planning on shooting some other footage in 1080i @ 23.98 for a different look. What kind of nightmares can I expect (if any) in mixing these two and what would my workflow be in terms of pulling it off?

  Thanks-
  Paul

  It depends on what your final target format will be. The fact that you’ve already got interlaced material at 29.97fps suggests that you’re probably not going back to film. If that’s the case, I would probably cut the entire show at 29.97/1080i.

  Assuming you’ll be offlining this at a lower resolution, what I would suggest is:

  – Downconvert all the 1080i/29.97 material to 480i/29.97 with matching TC. Use the ANAMORPHIC setting of the HDCAM deck during the downconvert, set your sequence for ANAMORPHIC as well within FCP.

  – Downconvert all the 1080p/23.98 material to 480i/29.97 with matching NON-DROP FRAME TC. At this point, 2:3 pulldown will be added to the downconverted output. MAKE SURE THIS IS PERFORMED CORRECTLY SO VIDEO,AUDIO AND TC ARE ALL IN SYNC. Same settings for ANAMORPHIC apply.

  – Ingest all your material into FCP at 480i/29.97 using the offline codec of your choice and edit away.

  – When it’s time to uprez, recapture the required 1080i material in the normal way. The 1080p material can be recaptured from the 2:3 HD output of the HDCAM (make sure and set the RS-422 “tc sense” to 30fps).

  That’s about it!

  All the best,
