Kerned pairs in Apple Motion

I am creating a custom font to be used in Apple Motion, a piece of video software that pairs with Final Cut Pro.

The kerned pairs that I have set up in my font are not displaying in Apple Motion, but kerned pairs do work in that program for other fonts on my computer.

The kerned pairs display just fine in Text Edit, so I was wondering if there is something I am not doing right.

MY FONT IN MOTION, NOT KERNING RIGHT:

I don’t have Motion to test this but I suspect it does not support OpenType Kerning. Can you try to add Write Kern Table custom parameter to the font info? It will try to write a old kern table. The problem is it can only contain a few pairs and no classes. You need to make sure the kerning fits.

OK, issue resolved.

As you recommended I added the Write Kern Table parameter to the instances tab of the font info window, since it’s a hidden parameter I pasted it in by copying this text:

> (
>         {
>         "Write Kern Table" = 1;
>     }
> )

I also had to export the file as a True Type font, as was recommended for Office users in this thread.

For posterity:
