PFTrack .ma importing at incorrect frame rate

[#1]

Hi, I am trying to import a .ma file that was exported from pftrack into after effects. In PFTrack the frame rate is set to 23.976 but when I import it into AE it comes in as a composition at 30 fps. I can't find a way to re-interpret the frame rate of a comp, and changing the frame rate in the comp settings isn't really an option because it messes up the tracking key frames.

Any help would be appreciated.

Yes it's possible to change the FPS check this small tutorial https://www.youtube.com/watch?v=GctfMN3IxuU

Hi OussK, thanks for the reply.

As I said in my post, the .ma comes into AE as a composition and the "interpret footage" option is grayed out.
