PFTrack .ma importing at incorrect frame rate

[swansonite07]

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.

Hi!

I found the solution. You have to edit the third line in .ma file that you exported from PFTrack.

like this:

//Maya ASCII 4.0 scene

requires maya "4.0";
currentUnit -l cm -a deg -t 23.976fps;

"Set the current time unit. Valid strings are:
[hour | min | sec | millisec | game | film | pal | ntsc | show | palf | ntscf | 23.976fps | 29.97fps | 29.97df | 47.952fps | 59.94fps | 44100fps | 48000fps]
When queried, returns a string which is the current time unit

Note that there is no long form for any of the time units. The non-seconds based time units are interpreted as the following frames per second:

• game: 15 fps
• film: 24 fps
• pal: 25 fps
• ntsc: 30 fps
• show: 48 fps
• palf: 50 fps
• ntscf: 60 fps"
