Just diving into FCPX and I had a question about hte alpha channel. After finding the setting in the inspector, I switched it to premultiply. However, it does not update in the timeline and upon clicking out of it, the inspector reverts the setting back to "ignore alpha." It does this whether I change the clip in the Project or the Library. The title animation was exported from After Effects with the Animation preset.
I assume it's something simple, however I'm going mad trying to figure this out.
