It is moving fastest * at the moment it is replaced, which is the oldest trick there is for hiding * an edit. * - **Every cut is followed by a glide, not a stop.** The frame arrives slightly * off and eases in — measured, the answer page lands 27px high and settles * down over 15 frames on an ease-out. Cut to a static frame and the edit is * the loudest thing in the shot. * * The only *move* in the whole reference is inside a shot, and there are two * kinds: a slow idle drift that never stops, and one fast blurred push to * whatever is about to happen. * * ## The pull-back is fitted to the content, not to the clock * * As the answer grows — paragraph, then headline, then four cards, then the * composer sliding up — the camera pulls back and rises to keep the block in * frame. Tracking the column's left and right edges across the move recovers a * scale of **1.404× → 1.0** about a fixed point at **(0.5, −0.548)** of the * frame: dead centre horizontally, and 273px *above the top edge*. Both edges * agree on that point to within 1px, which is what makes it a measurement and * not a guess. A focal point above the frame is the whole reason the page * appears to rise as it shrinks, instead of collapsing toward its middle. * * Peak velocity sits at 48–52% of the move, so the curve is a cubic in-out — * see `shotBScale`.
