Re: HD 25fps - 29.97fps frame rate best conversion by gary adcock on May 30, 2008 at 11:44:25 am
[PETER LEE-JONES]"Why would I want to go to 23.98?
My delivery format is 29.97 "
Because that is the standard method for converting between the NTSC and PAL frame rates.
by conforming the the clip in CT to 23.98, and then adding pulldown to get your output to 29.97- you can achieve the conversion. It will not be as accurate as going through a teranex, but it does work.

There is a caveat to the 25 to 23.98 conform process. Your TRT will grow by 4% and your audio with shift in pitch.
A quick way to pitch correct the audio is to conform the video, note the new TRT. Take the 25fps audio into soundtrack and use the time stretch process. Enter in the new TRT, render and output.

I believe that the 5500 can playout 25 as 23.98 and pitch correct the audio at the same time. But what that would do to your audio encode I do not know.
