Error when sending animation to FCP?

My settings on istopmotion look like this
Pixel Aspect Ratio- HDV1080 (4:3) 1.333
Starting offset 00:00 Timecode
Export Settings- HD 1080p25
Preview- Default

And when I send it to Final Cut Pro it gives me an error saying the footage will not work properly due to settings? What should I set on FCP, it doesnt seem to really have an option for HD1080p25.
When you try to play the film on FCP, it plays really slow (im using 15fps) but in the past, istopmotion would automatically put in a keyframe every 24f, I can’t seem to find this feature anymore.

I am fairly new at this, I appreciate your help!
Thank you
