If there are multiple effects, you might try playing with the order of the effects. Another thing if you are just using it on the one clip, you might nest the clip and apply the swivel effect to the nested sequence.
Hope this helps,
*UPDATE: Problem solved.
Looking for a solution as well...
I figured out, that it's only getting cropped when the footage's size is equal to or greater than than that of the sequence.
In the picture at the top the sequence has a resolution of 1920x1080. Notice how the left video stays untouched while the right one gets cropped. The left one has a native resolution of 1280x720 while the right one is in 1920x1080.
/edit: Found a solution:
dradeke's workaround should work fine, as well. But if you don't want to nest your clip for whatever reason you might have: You just have to add a "Transform" effect ABOVE your "Basic 3D" one and do all the 'motion' related attributes (scaliing, position, etc...) with this one.
