What it does
The technique catalog: five velocity-matched SEAMS (zoom-through, INVERSE zoom-through, cut-the-curve, waterfall cut, rack-focus blur-cut) plus the two in-scene techniques, waterfall ENTRY (staggered arrival cascades for title cards / segment openers) and the nudge curve (slow-fast-slow three-phase group slides). Covers partial-travel (~12% of frame) velocity matching via mirrored power4 eases, the Z scale-sign rule, size-scaled blur (10px text / 18-20px full-frame), word-by-word staggered cuts, cascade pacing by element weight, and the 10/65/25 slide ratio. Read before authoring any transition, text-beat handoff, kinetic text entry, or group reposition. [depth, zoom, inverse-zoom, scale-sign, mirrored-zoom, rack-focus, pacing, velocity, cut-the-curve, waterfall, stagger, cascade, kinetic-text, title-card, segment-opener, nudge, slide, easing, group-motion, z-depth, motion-graphics, cinematic, transition, blur, directional-continuity]
Cut the Curve, the technique catalog
Five SEAM techniques, one principle: cut at peak velocity, match direction and speed
on both sides of the cut, plus the two in-scene techniques (§6 arrivals, §7 slides).
The seam LAW, vector law, the current, the ledger, the Seam Gate, lives in
motion-doctrine; read it first. This skill is the parameters and mechanics.

Catalog
| # | Technique | Scope | Axis | Use for |
|---|---|---|---|---|
| 1 | Zoom-Through (forward) | Within-scene text swap | Z, toward viewer | progressing deeper into the same thought |
| 2 | Inverse Zoom-Through | Arrival / payoff beat | Z, away from viewer | something bigger lands |
| 3 | Cut the Curve | Between scenes | X / Y | the default boundary, the film's current |
| 4 | Waterfall Cut | Text-to-text seam | X, per-word | word-level handoff between big-text beats |
| 5 | Rack-Focus Blur-Cut | Same-surface state swap | X / Y / Z | the one cut you want SEEN, a DSLR focus-pull flourish |
| 6 | Waterfall Entry | In-scene ARRIVAL (no seam) | Y, from below | title cards, segment openers, list intros |
| 7 | Nudge Curve | In-scene group slide (no seam) | X / Y | repositioning a composed group to make room |
Z direction is a sign
"Same axis" is not enough on Z, the sign of d(scale)/dt must match across the cut:
