Gas transformation effect

On a footbridge one person turns to vapour while the other stays solid. a wide shot of two people standing on a plain footbridge in still morning air, the one on the left thins into translucent grey vapour that keeps their silhouette for a beat then drifts sideways over the railing and thins out, the one on the right staying completely solid with clothes, hair and a shadow on the deck, the bridge and the water below unchanged, locked wide camera

A standing figure becomes amber gas that spreads across a wide workshop. a wide shot of a bare workshop with a concrete floor, a standing person thins from the head down into bright amber translucent vapour that spreads low and wide across the room, flowing around the legs of a heavy workbench and rising in slow sheets, the bench, the tools and the shuttered windows staying completely solid, the amber light reflected faintly on the floor, locked wide camera

A loose cloud tightens downward and settles into a solid standing figure. a loose cloud of pale vapour hangs in a narrow corridor, it tightens from the top down and gains density until a solid standing person is there with clothes, skin and a hard shadow on the floor, the last wisps pulling in at the wrists and collar, the corridor walls and the ceiling light unchanged the whole time, locked camera at chest height

A seated figure gasses off and the vapour becomes visible crossing a light beam. a person sits on the floor of a dim attic with one hard shaft of daylight crossing the room, the body thins into translucent vapour that rises and becomes bright and clearly readable as it passes through the beam, then dims again above it, the dust already in the beam giving a reference for scale, the floorboards and the roof timbers unchanged, slow tilt up following the rise

A standing person turns to grey vapour from the feet up and rises. a person stands still in a bare room with a single window, the body begins to lose density at the ankles and the loss travels upward so the legs and torso become translucent grey vapour that still holds the exact silhouette, the shoulders and head going last, then the whole column loosens and drifts up toward the ceiling in slow curling ribbons, the floor, the window frame and the light unchanged, locked camera

A raised hand streams green vapour while the rest of the arm stays skin. a close vertical shot of a raised open hand against a dark plain wall, the fingers lose density and stream away as bright green translucent vapour that curls upward in the still air, the wrist and forearm below staying completely solid skin with a clear edge where the change stops, the green light faintly reflected on the arm, no other colour in frame, locked camera

A single chair in a hall turns to vapour and leaves the row otherwise intact. a wide shot of a long row of plain wooden chairs in an empty hall under flat ceiling light, the third chair from the left thins into translucent grey vapour that keeps the chair outline for a moment then rises and thins away to leave a clean gap in the row, every other chair staying solid and sharp with its shadow on the floor, locked wide camera

One side of a seated figure stays solid while the other side has gone to gas. a close vertical shot of a person seated at a plain wooden table in soft side light, the left half of the body is completely solid with skin, cloth and a visible shadow, and the right half from shoulder to hand has become translucent vapour whose edge curls and lifts where the arm should be, the tabletop showing through the gas side, the two halves held in the same frame for the whole clip, slow push in

Vapour rolling off the sea tightens into a solid person at the waterline. a wide shot of an empty beach at first light, a low bank of pale vapour rolls in off the water, gathers at the waterline and tightens upward into a solid standing person with clothes, hair and a shadow on the wet sand, the last wisps pulling into the shoulders, the sea, the sand and the flat light unchanged throughout, locked wide camera

A single jug turns to vapour while every other object on the shelf stays solid. a close vertical shot of a plain kitchen shelf holding a row of five unbranded ceramic jugs in flat daylight, the jug in the middle thins into translucent grey vapour that holds the jug shape briefly then rises and thins away, leaving a clean gap on the shelf, the four jugs on either side staying completely solid and sharp for the whole clip, locked camera
