Need advice to further reduce jitteriness in short photo animation

What I have done so far:

In After Effects:

• Imported photo from Photoshop

• Animated its position from toes to head on the Timeline

• Rendered at Best Settings from within AE. Result too jerky, almost stobe-like, especially on diagonal edges of high contrast

• Recreated layer by adding Drift Over Time effect. Better, still jerky/strobey, but a little less so.

• On both layers, Motion Blur was turned onion general and on the layers themselves and enabled by the render settings.

• Motion Blur settings in the Advanced panel of the comp settings all maxed out except Shutter Angle, which just blurred the photo.

In Premier:

• Imported the rendered footage from AE

• Applied Warp Stabilizer effect. Settings: Smooth Motion, 100% Smoothness, Method: Subspace Warp. In Advanced: checked Detailed Analysis, Rolling Shutter Ripple, Enhanced Reduction.

Have all latest versions of software, on Mac OSX.7.5

This is the result. (it is a little sexy, but not porn or anything--barely PG-13, I'd say.) Watch in Full Screen Mode.

I think it is still rather jittery, especially on the diagonal lines of her thigh and hip.

Is there anything else i can do? (evidently, Frame Blending does not work on still photos.)

Thanks!
