Morph cut
Blend two takes so the join disappears. Two takes of the same person are joined by smoothly interpolating position and pose, so nothing jumps as in a jump cut.

How the movement works
To tighten an interview or narration, or to remove a slip without drawing attention.
- 01Take 1 (0–2.0 s): fixed camera (height 1.45 m); the person stands 0.4 m left, 3.3 m away, arms and legs at -0.45 rad. Take 2 (from 2.45 s): 0.35 m right, +0.55 rad. Both sway slightly by 0.12·sin(t×3) rad
- 02Morph (2.0–2.45 s, 0.45 s): the position is interpolated with a quadratic ease-in-out (about cubic-bezier(0.45,0,0.55,1)), and the two poses are drawn at the same interpolated position and cross-faded
- 03Only during the morph a blur of sin(q×π)×2.2 px is applied to the whole frame to soften the join (#041 Jump cut lets the position jump)
- 04Bottom strip: take 1 (grey), morph (blue, narrow), take 2 (grey) with a playhead
- 05Return: cross-fade back to the start of take 1 over the last 0.5 s; top-right readout shows "TAKE 1" → "MORPH" → "TAKE 2"
Prompt
Remove the repeated sentence in the interview with a morph cut, so the join is invisible.
