A question for the more experienced postpro experts here...
A film i worked on had to change its FPS from 24 FPS to 25 FPS and therefore now has a different duration.
Unfortunately i produced the sound design to the 24 FPS version of the film. I exported the mix of my sound design as a 48Khz WAV file.
By which factor do i have to pitch my exported WAV up or down to match the films new duration to ensure everything is back in sync if i align film and WAV at frame 0?
The tiny change in pitch does not matter (sonically) in my scenario. Therefore i want to do a pitch and not timestretch to avoid artifacts.
Any help would be greatly appreciated!
