The camera stopped at every key: each stretch between two keys eased in
and out on its own. Each value now follows a monotone cubic through the
keys, so it keeps its speed through a key, never runs past one, and only
eases at the first and last key.
The moved picture shook. The depth model guesses the lens again for every
frame, the depth-scale smoothing kept the frame-to-frame wobble instead of
removing it, and still things got a slightly different depth each frame.
Every frame now uses the clip's median lens, each frame's median depth
follows the smoothed line, and the depth of spots that hold still is
averaged over nearby frames. With the camera held at one angle the guide
now moves 0.02 px a frame between frames, against 0.28 before and 0.04 in
the source clip.
