1080i50 25fps PAL to 24fps for 3D model mapping
I have 1080i50 XDCAM PAL footage that needs to be edited into a series of sequences that will ultimately be projected or texture-mapped onto the face of a 3D object. The company handling the 3D modeling & animation is requesting Quicktimes running at 24fps.
My question is this: should the Quicktimes be exactly 24 fps for the sake of working in a 3D application or instead be 23.976? (The entire completed project with all elements will most likely be projected on a screen at 1920×1080 29.97). And what is the best way to accomplish this framerate conversion, from 25fps to 24 or 23.976?
I’m also posting a similar version of this in the After Effects forum…
Thanks!

Hi Mike,
Where did you get the footage and where will it be shown? USA, Europe?
That will be key to determining your master framerate, but you dont need to go from 25fps to 23.976 to 29.97…that will unnecessarily compromise your footage. Any 3D animation program will be able to handle the footage at any framerate and full HD.
So consider cutting in 25fps as close to master format as your system will allow, then export to 3D house at 25fps.
They execute project at 25fps and final masters are in any required conversion format.
So for web, why not just export as 25fps…quicktime doesn’t care, only monitors and format specific decks. So, for TV export an NTSC version (with letterbox hopefully) and an HD version for that broadcast format. But even those can be delivered digitally today.
Any questions let me know and good luck.
