Elastic Reality has been used a great deal for making tweens for animation. Just ask the belly dancing Ritz(r) crackers or the Coke(r) sun :-). You should take key frames from your animation source, probably twice a second (assuming you working with 24 or 30 frame frame rates). Load the project up as if it were a moving morph. Duplicate all the source frames (all A roll images being the same source frame). Do the same for the B roll. Trace the shapes you want to control on the first frame of the A roll. Select them all, then copy (EDIT/COPY) them. Then shift into the B roll and PASTE them on the first image of the B roll. Move to the last image of the B roll then tweak the shapes so they line up on the last image only. In render options set the check box Don't Render B roll. Perform the morph as usual….pixels will be picked up from the A roll where they were supposed to come from and will be deposited in a tweened location between the first key frame (the a roll) and the next key frame (the b roll). You can control the rate of interpolation from the source to final shape using the motion curve for groups you've assigned (if any). And, you can add tweaks to the motion in the B roll if necessary.
