Concise method to convert 24fps sequence to 23.98 for Blu-Ray output

Is there any particular reason why you can’t just make a 24fps BluRay.
There really should be no reason why you would have to use 23.976.

I need a 23.976 Blu-Ray as part of a deliverables list.

Kind of weird that the project would have been shot in true 24 and they would want a 23.976 BluRay.

Getting a proper 23.976fps Video from the True 24 Video would be done through a TeleCine Process. To get the best results your 24fps Video will need to be slowed down by 0.1%. This will change the Real Time Playback of the Video though. As a simple example, if it is exactly 1 hour long at 24fps it will take 1:00:03:14 to play it back at 23.976.

I’ve never tried AME to see if it can do a proper TeleCine conversion but it couldn’t hurt giving it a try. You will want to check for three things. Is the Converted Video 0.1% longer than the original, are there any repeat Frames and are there any blended Frames. The answer should be no to the lat two.

There are a few ways to do the Reverse Process some are hardware based like The Alchemist and possibly a Terranex can do it but don’t quote me on that. As far as software goes I can’t say I’ve researched this so start off by testing AME.

I have a feature length film edited in Premiere Pro CC 2017 at true 24fps, that I will need to deliver at 23.976 for Blu-Ray.

24fps can be used for Blu-ray without any conversion to 23.976 since 24fps is a supported frame rate for 720p/1080p/4K. I have made several Blu-rays in 24fps and i have bought several commercial Blu-ray discs that are 24fps.

See “Supported video formats” here: https://en.wikipedia.org/wiki/Blu-ray

Why the urge to convert the footage? 🙂

You could try export a ProResHQ of your 24fps film – import that file – right click and re-interpret frame rate to 23.976 – the file now thinks it’s a 23.976 clip, it should look and sound fine. Drag the clip to a new 23.976 sequence – set in and out and export a ProRes or MPEG2 etc for a 23.976 BluRay project.
