  playing 24fps back with 25fps

  Posted by Andi Winter on February 14, 2011 at 1:54 pm

  hi all!

  i want to playback a 24fps footage with 25fps WITH sound, to then simply record the output on another device in SD for DVD-creation.

  the framerateconversion seems to be pretty good, but the sound seems to get unsync right from the start.
  do i have to change something to get this to work? tried to change the audio in “conform room” to 25 fps, still not sync. any ideas?

  i think this should be possible, shouldn’t it?

  any experiences?

  I am not sure about resolve (never tried this ) , but usually to go from 24 to 25 you have speed up the footage and audio by 4%,
  usually the video speed up is handled by the color grading app (changing the framerate (or exporting a QT and than using cinema tools ), but you need to speed up the audio by itself in protools or something , than re import (merge it back together on 25 project )it in the app for playback and sync ..

  this is the typical workflow for 24 to Pal (for example how SCRATCH does it)
  I am curious if resolve changing the speed of the project it will actually play it back 4% faster (which it should) and not trying to keep the same length interpolating and duplicating frames (like final cut does and than will look horrible)

  thx g

  yes, i know this would be the alternative workflow. but i also think davinci should speed up the audio by 4.1% automatically if i switch to 25fps…

  strange it doesn’t…

  mmm… anyone can confirm that resolve should slow down audio ?
  how it does it ? (audio pitch wise )…
