How do I copy and paste motion attributes?

Sadly, you can't copy and paste keyframing in FCP X - let's hope we get that facility soon.

One of my free plugins can be used as part of a workaround.

The first thing to note is that as it works as an effect, it cannot change the look of anything that's outside the boundary of a clip it's applied to. If your clip is smaller than full screen, you need to turn it into a compound clip, so my effect can work with the whole frame.

Use my Alex4D Smooth Move effect. With it you can choose a start and stop position, scale, rotation for a clip.

If you want to apply distinct colour, sound, and other effects to your clips that you don't want to copy to other clips along with your moves, if you make the changes first and make the clip into a compound clip, those changes are now stored 'further inside' the clip. That means when you copy the clip and then paste effects to some other clip, only the effects applied to the compound clip will be pasted, not the effects applied to the clip(s) in the compound clip.

For FCPX transformations, cropping, distortion, etc... NOT including any added motion effects, additional "plugins" etc... just the stuff you can do in FCPX to a clip:

Copy the clip with the keyframed changes and Option-Command-V on the clip you want to copy the keyframes to (make sure they'll fit, i.e., do the shortest clip first and copy that one.) Your keyframes will be applied to the new clips.

IF you have effects and other stuff you already did to your clips (including color corrections!):

Make each clip you need to copy or paste FCPX keyframes onto a compound clip first (select and Option-G), otherwise, you will whack all your effects and apply the motion effects that were applied to the original animated clip (make sense??) You can isolate "actions" to clips by compounding them. It is *better* to plan ahead and create the actions that will be copied first before adding motion effects, color corrections etc. Too many "layers" of compounding slow things down; but one or two layers won't be too much of a burden.
