I have been doing Ken Burns type effect in both FCP and Avid but would like to smooth the edges so if you do a zoom/direction change during the shot it does not jolt. For example if you do a zoom into to a person and then stop zooming to leave the CU of them for a few seconds when you stop zooming it is abrupt, I want it to slow down progressively and come down to a soft landing.
Yes as John says you can do this by automatically adding and Easy Ease to the motion keyfrmaes. Further tweaking can be applied if necessary using the Graph Editor.
After Effects also has a Keyframe Assistant specifically for this purpose to ensure an even speed when panning or zooming using the Scale property. It's name is a little off-putting but it's very easy to use, it's called (wait for it) "Default spatial Interpolation to Linear" Phew!
There are also lots of free animation presets for After Effects that will automatically add these kinds of Ken Burns effects with a drag and drop. you can Browse the free animation presets by going to Animation > Browse Presets. This will open Adobe Bridge where you can see previews of the presets before applying them.
Here's a link to a list of presets in the Help. you can also check here for info regarding the keyframe assistant I spoke of earlier.
Incidentally, you can also do some of this in Final Cut Pro.If my memory serves me correctly you can right-click on a keyframe in FCP (7) and choose to Ease it or Smooth it.
Hope this helps! You'll love After Effects! :-)
