In film you would just give the film to the projectionist and they would run a 25fps film at 24fps. For DCP you could export the film as DPX files and then import them into the DCP package as 24.00 FPS. You could render a 25FPS Quicktime and use Cinema Tools (FCP 7) to “Conform” the clip from 25.00 FPS to 24.00 FPS which is just a QT header change. Open the clip in Cinema tools and click on the conform button to to change the frame rate.

Converting the image files to 24 fps is easy, but you also need to slow down the audio and fix the pitch so it stays the same.

DCP doesn’t support 25 fps?

You mean “Old Ben”? Ben Kenobi?

How do I go about doing this from 25 to 24 for Blu-ray please?
It’s a concert film, so screwing with the audio is not an option – too many artefacts from time stretching & pitch shifting, so what IO was considering was a straight 25-24 conversion that extends the run time, and shrinking the footage back to the right length using something like Twixtor – but 4.1% is a huge amount.
The worst of this is that the film crew were asked to shoot at 24, yet refused saying ‘we always fix it in post’ which is utter BS of course.

Quickest way is to use Adobe Media Encoder.
From my experience.And when you say BluRay, do you mean its still an editable format e.g. ProRes422 and wish to convert to burn onto BD correct?
AME it is.
