Howler tutorial: Frame Blending vs. Motion Estimated Interpolation for super slow mo [Commer cial]
Here's a tutorial that compares 3 methods for slowing an animation, originally consisting of just 4 frames, and turned into 200+ frames for smooth, super-slow motion.

This castle's 3D model is a massive 3D reconstruction, has millions of polygons, and takes over an hour to render each frame at 960x540.
It's particularly useful when, like in this example, the 3D model is so big that it takes hours to render a few frames, and you just can't see yourself rendering a 5 second animation at 30 fps.....
Motion estimation can often produce high quality tween frames, good enough that you can spare the time to render the extra frames. It isn't applicable to all scenarios, but here's one that works. In other cases you might notice slight glitches, but the time saved on extra 3D rendering is easily compensating for the time spent on fixing the glitches.
PD Howler, powered by Project Dogwaffle, is available ere at DAZ. The Motion Prediction Module has been available since version 7.2
So ask yourself: What are YOU gonna tween today?
