abstract-transitions

ABSTRACT · TRANSITIONS — six short rooms for the same phone, and the five handoffs between them are the subject. Each scene is 2.5 s of a set the reel already knows (a kit row, a ring corridor, a capsule field, a cube grid, a halo, an eclipse); the gaps are five DIFFERENT transition kinds, so cutting this file at any gap shows one handoff in isolation.

# scene dur → next by the room
01 t01-row 2.5 match-move (0.8) the phone with a cube and an icosphere on a mirror floor
02 t02-corridor 2.5 through=t02-phone (0.9) the ring corridor; the camera flies INTO the phone's glass
03 t03-field 2.5 whip-pan shader + transition-camera=whip-left the phone floating in a capsule field
04 t04-grid 2.5 flash-through-white (0.5) the phone rising in the cube grid
05 t05-halo 2.5 slice shader, 9 strips, accent-tinted the phone in three rings
06 t06-eclipse 2.5 — the phone against the disc

15.0 s of scene + five gaps (3.3 s) ≈ 18.3 s on the wall.

THE FIVE HANDOFFS, and what each one asks of the scenes either side:
· MATCH-MOVE — a run-on morph on shared match= keys. Both scenes carry
match=hero on the phone and hz0/hz1/hz2 on the haze; everything else
crossfades under the morph. Nothing in either scene may fade IN over
the flying phone (the veil trap).
· THROUGH — the camera flies into an element of THIS scene; the next
scene opens on its own first row. t03's first row is close on the
phone so the arrival reads as "inside, then out".
· WHIP-PAN — a full-frame shader gap with a camera program layered over
it (transition-camera=whip-left). Shader gaps are EXCLUSIVE with
match/through: matched elements only crossfade under them. t03 is
the only room whose phone has no floor, so the whip has nothing to
smear but the field.
· FLASH-THROUGH-WHITE — the reel's own s04→s05 gap. 0.5 s; the white
hides the cut, so the two rooms may differ completely.
· SLICE — strips that slide off in alternation; transition-shader-strips
sets the count and transition-accent tints them.
