[Subject]
One fictional AERIS Fold travel kettle remains identical throughout the video:
a compact matte-silver cylindrical body, a translucent smoke-gray handle,
a thin cobalt temperature ring, and a small wordless circular control.
The setting is a quiet sleeper-train cabin before sunrise. The core event is
the kettle unfolding, heating one cup of water, and returning to its compact form.
No people appear.

[duration and aspect ratio]
+ [capture or animation style]
+ [lighting and palette]
+ [materials and texture]
+ [camera rhythm]

[Style]
15 seconds, 16:9, premium live-action product film with invisible CG integration.
Blue-hour window light, warm amber practical lamps, deep navy shadows, restrained
highlights, realistic brushed metal, clear steam, and subtle train vibration.
Use macro details, controlled lateral tracking, and brief speed changes around
mechanical actions. Clean image, natural motion blur, no futuristic neon.

[time] Starting state + subject action + camera direction + ending state

[Timeline]
[0:00-0:02] Extreme macro of a narrow cobalt light ring in darkness. The ring
activates with one clean pulse as the camera pulls back to reveal the compact kettle.

[0:02-0:05] The handle rotates outward from its real hinge and locks. The lid rises
five millimeters and seals again while the camera tracks left at tabletop height.

[0:05-0:09] Water begins to heat. Condensation forms inside the small viewing window;
the train passes through a tunnel and warm cabin reflections travel across the shell.

[0:09-0:12] The kettle pours one precise stream into a ceramic cup. The camera follows
the stream downward, then settles beside the cup as steam catches the window light.

[0:12-0:15] The handle folds back into the body. Dawn appears beyond the window.
End on a stable three-quarter hero frame of the compact kettle beside the filled cup.

[BGM]
Minimal 104 BPM electronic score built from soft felt percussion, low warm synth,
and a restrained glass pulse. Begin with only the pulse; add the beat when the handle
locks at 0:03. Reduce the music during the pour at 0:09, then resolve on one warm chord.
Keep realistic hinge clicks, a quiet heating hum, water pour, cup resonance, and low
train ambience clearly audible. No voice-over and no sung vocals.

[Constraints]
Keep one identical kettle in every shot. The handle rotates only from its visible hinge;
no floating parts, duplicated lid, changing proportions, or liquid passing through solid
surfaces. Keep the cup fixed on the table and preserve the same cabin layout. No hands,
faces, extra appliances, readable text, invented logo, subtitles, watermark, black bars,
or final fade to black. Hold the last hero frame steady and fully visible.

[Subject]
Define the recurring subject or product, the setting, the core event, and the role of
every reference asset. State which identity, shape, wardrobe, or material must persist.

[Style]
15 seconds, [aspect ratio], [capture or animation treatment]. Describe lighting,
palette, texture, lens behavior, camera rhythm, and image quality.

[Timeline]
[0:00-0:02] Hook: starting state + first visible action + camera move + ending state.
[0:02-0:05] Development beat.
[0:05-0:09] Main action or transformation.
[0:09-0:12] Payoff or reveal.
[0:12-0:15] Resolution and stable final frame.

[BGM]
Music style, tempo, emotional curve, dialogue or voice-over, ambience, and synchronized
sound effects. State what must remain audible and whether vocals are allowed.

[Constraints]
List the 3-8 failures most likely to break this exact video. Lock subject identity,
spatial continuity, action physics, protected regions, text policy, and final frame.

[Subject]
Recurring subject + setting + narrative objective + reference responsibilities.

[0:03-0:08] Establish the subject and space.
[0:08-0:13] First development.
[0:13-0:18] Escalation or transition.
[0:18-0:24] Main payoff.
[0:24-0:28] Resolution.
[0:28-0:30] Stable end card, hero frame, or emotional landing.

[BGM]
Score, dialogue, ambience, synchronized effects, and the musical ending.

[Constraints]

[Subject]
One fictional AERIS Fold travel kettle remains identical throughout the video: compact
matte-silver cylindrical body, translucent smoke-gray folding handle, thin cobalt
temperature ring, and a small wordless circular control. The setting is a quiet premium
sleeper-train cabin before sunrise. The kettle unfolds, heats one cup of water, pours it,
and returns to its compact form. No people appear.

[Style]
15 seconds, 16:9, premium live-action product film with invisible CG integration.
Blue-hour window light, warm amber practical lamps, deep navy shadows, restrained
highlights, realistic brushed metal, clear steam, and subtle train vibration. Macro
details, controlled lateral tracking, and brief acceleration around mechanical actions.
Natural motion blur, shallow depth of field, no futuristic neon.

[Timeline]
[0:00-0:02] Extreme macro of the cobalt ring in darkness. It activates with one clean
pulse as the camera pulls back to reveal the compact kettle beside an empty ceramic cup.
[0:02-0:05] The handle rotates outward from its real hinge and locks. The lid rises five
millimeters and seals while the camera tracks left at tabletop height.
[0:05-0:09] The water heats. Condensation forms inside the viewing window as tunnel
reflections travel across the brushed shell. The cup remains fixed beside the kettle.
[0:09-0:12] The kettle tilts and pours one precise stream into the cup. The camera follows
the stream down and settles beside the cup as steam catches the window light.
[0:12-0:15] The kettle returns upright and the handle folds into the body. Dawn appears
beyond the window. End on a stable three-quarter hero frame beside the filled cup.

[BGM]
Minimal 104 BPM electronic score with felt percussion, low warm synth, and a restrained
glass pulse. Add the beat when the handle locks. Pull the music back during the pour,
then resolve on one warm chord. Keep realistic hinge clicks, quiet heating hum, water,
cup resonance, and low train ambience. No voice-over and no vocals.

[Constraints]
Keep one identical kettle in every shot. The handle rotates only from its visible hinge;
no floating parts, duplicated lid, changing proportions, or liquid passing through solid
surfaces. Keep the cup and cabin layout consistent. No hands, faces, extra appliances,
readable text, invented logo, subtitles, watermark, black bars, or final fade to black.
Hold the last hero frame steady and fully visible.

Image 1 defines [identity or design] for [time range].
Image 2 defines [location or palette] for [time range].
Video 1 defines [camera or action] only for [time range].
Do not inherit [actor, background, color, wardrobe, or objects] from Video 1.

[Subject]
Image 1 defines Subject A's adult face, short black hair, charcoal suit, and red gloves
throughout the full video. Image 2 defines the empty museum architecture, sculpture
positions, and cool white lighting. Video 1 defines only the forward corridor-dolly path
from 0:03 to 0:08. Do not inherit the actor, wardrobe, walls, furniture, or warm color
grade from Video 1. Subject A follows a thin trail of red thread toward one marble statue.

[Style]
12 seconds, 16:9, elegant live-action mystery film. Cool limestone, soft overhead pools
of light, controlled reflections, restrained contrast, 40mm lens, measured camera motion.

[Timeline]
[0:00-0:03] Wide locked frame: Subject A enters the empty gallery from frame left and
notices the red thread crossing the floor. End with her right foot beside the thread.
[0:03-0:08] Reproduce only Video 1's forward camera path as Subject A follows the thread.
Keep the gallery from Image 2 and her appearance from Image 1.
[0:08-0:12] The thread rises from the floor and wraps once around the statue's wrist.
The camera stops; Subject A stops one meter away. End on a stable two-subject composition.

[BGM]
Sparse bowed-glass score, quiet room tone, soft footsteps, and one thread-tension sound.
No dialogue.

[Constraints]
Keep Subject A's face, suit, gloves, and body proportions stable. Keep one thread and one
statue. No inherited person or furniture from Video 1, no extra visitors, no wardrobe
change, no moving sculptures, no text, logo, watermark, or final black frame.

initiator + origin + path + target + contact + landing or end state

[0:05-0:08] Subject A removes one brass key from the left pocket of her apron with her
right hand, turns her wrist outward, and throws the key in a shallow left-to-right arc
across the workbench. The key remains visible in flight. Subject B catches it once in his
open left palm at chest height, closes his fingers around it, and lowers the same hand to
the bench. The camera pans right with the key and stops only after the catch is complete.

One continuous shot with no cuts, wipes, flashes, hidden edits, or viewpoint resets.
The camera moves from [starting position] through [path] and ends at [final position].

[Subject]
One adult baker in a navy apron opens a small corner bakery before dawn. One continuous
shot follows the first tray of croissants from the oven to the front window.

[Style]
14 seconds, 16:9, warm observational live action, 35mm lens, gentle handheld stability,
amber practical light inside and cool blue street light outside.

[Timeline]
One continuous shot with no cuts, wipes, flashes, hidden edits, or viewpoint resets.
[0:00-0:04] Start inside the open oven at tray height. The baker pulls out one tray while
the camera retreats backward into the kitchen, maintaining the same screen direction.
[0:04-0:09] The camera arcs around the baker's left side as she carries the tray forward,
then passes naturally behind a hanging copper pan without cutting.
[0:09-0:14] Continue through the service doorway and settle outside the front window as
she places the same tray on display. End with her switching on the OPEN light from inside.

[BGM]
Quiet brushed percussion, oven fan, tray rattle, footsteps, morning traffic, and one switch
click. No dialogue.

[Constraints]
No cuts, teleportation, speed ramps, camera reset, duplicate tray, changing pastry count,
identity drift, extra staff, unreadable signage, watermark, or black ending.

Extend Video 1 forward by [duration].
Begin from its exact final [pose, framing, direction, light, and sound].
Continue with [new action beats only].
Do not replay or summarize the source clip.

[Subject]
Extend Video 1 forward by 8 seconds. Begin from the exact final frame: the same adult
traveler stands at the ferry rail facing frame right, holding one yellow duffel bag as
the harbor enters view. Preserve face, coat, bag, weather, vessel, lens height, camera
drift, travel direction, and the original engine-and-wind ambience.

[Style]
Continue Video 1's natural overcast live-action look and restrained handheld motion.

[Timeline]
[0:00-0:03 of extension] The traveler lifts the yellow bag from the deck with her right
hand as the ferry slows. The camera continues the source clip's slight forward drift.
[0:03-0:06] The boarding ramp touches the dock. She turns toward frame left and takes
two steps, preserving her screen direction after the turn.
[0:06-0:08] She pauses at the ramp as a lighthouse foghorn sounds. End on her looking
toward the lighthouse, with the harbor still moving gently behind her.

[BGM]
Continue the original ambience seamlessly. Add only ramp contact, two footsteps, and one
distant foghorn. Do not add music or speech.

[Constraints]
Do not replay the ferry approach or repeat her rail pose. No cut at the extension seam,
identity change, wardrobe change, new passenger in the foreground, weather change,
camera jump, subtitle, logo, watermark, or fade to black.

At [time], in [screen location], change [target] from A to B.
Keep [camera, timing, subject, background, lighting, occlusion, and sound] unchanged.

[Subject]
Edit Video 1 only from 0:02 to 0:07. Replace the small white plastic lamp on the rear-left
side table with one amber ribbed-glass lamp of the same height and footprint. Preserve
the actor, face, hands, clothing, sofa, coffee table, wall art, window, camera movement,
timing, focus, exposure, occlusions, shadows, and every other object from Video 1.

[Style]
Match the source video's live-action optics, grain, warm evening light, and depth of field.

[Timeline]
[0:00-0:02] Source video remains pixel-consistent; no change.
[0:02-0:07] The replacement lamp occupies the original lamp's exact position and remains
correctly hidden whenever the actor passes in front of it. Its amber light affects only
the nearby wall and side table with realistic falloff.
[0:07-end] Preserve the replaced lamp and continue the original video unchanged.

[BGM]
Keep the source audio unchanged. Add no music, dialogue, or effects.

[Constraints]
Edit only the lamp and its local light contribution. Do not alter the actor, face, body,
furniture, framing, camera path, focus, wall color, clip duration, or audio. No duplicated
lamp, transparent actor, broken occlusion, flicker, text, logo, or watermark.

[Observed structure]
The reference contains four shots over approximately 12 seconds. Each cut is motivated
by one circular object occupying the center of frame: a cup rim, a bicycle wheel, a clock,
and the moon. The camera moves clockwise in every shot. The cuts occur when the circular
shape reaches roughly the same size and screen position. Music adds one percussion hit at
each cut. The exact lens and frame rate are unknown.

[Reconstruction prompt]
[Subject]
Create an original four-shot city-at-night sequence using a record, a laundromat dryer,
a taxi wheel, and a full moon as the four circular anchors. Do not copy people, locations,
wardrobe, brands, or color design from the reference.

[Style]
12 seconds, 16:9, rainy live-action city film, black asphalt, sodium amber, muted teal,
natural reflections, controlled clockwise camera motion.

[Timeline]
[0:00-0:03] Macro record spinning clockwise; push in until the label circle fills center.
[0:03-0:06] Match cut to a dryer window at the same scale; pull back as clothes rotate.
[0:06-0:09] Match cut to a taxi wheel; track beside it through one shallow puddle.
[0:09-0:12] Match cut to the full moon reflected in the puddle; tilt up to the real moon
and end on a stable skyline.

[BGM]
Original 96 BPM downtempo electronic score. One dry percussion hit on each match cut,
plus rain, vinyl texture, dryer hum, and one taxi pass.

[Constraints]
Keep every circular anchor centered and rotating clockwise before its cut. No copied
actor, location, brand, text, transition order, sudden camera reversal, watermark, or
black ending.

[Subject]
One unbranded folding chair shown as a clean clay-white engineering model. The seat,
backrest, front legs, rear legs, two hinge pins, and two cross braces remain geometrically
consistent. Demonstrate one complete fold and unfold cycle.

[Style]
10 seconds, 16:9, high-key product-visualization render on a seamless light-gray studio
background. Soft contact shadows, matte clay material, thin cobalt highlights only on
active joints, orthographic-like 50mm view, precise mechanical motion.

[Timeline]
[0:00-0:02] Three-quarter view of the fully open chair. Cobalt highlights identify the
two hinge pins while the camera makes a slow 20-degree orbit.
[0:02-0:05] The seat rotates upward around the real hinge axis; the cross braces fold
inward and both leg pairs approach each other without intersecting.
[0:05-0:07] Hold the fully folded state for one second as the camera reaches side view.
[0:07-0:10] Reverse the same joint paths to return to the fully open chair. End still.

[BGM]
No music. Quiet studio tone, two hinge movements, two soft mechanical locks.

[Constraints]
Keep fixed part count and real hinge axes. No bending metal, elastic legs, intersecting
parts, floating pins, extra braces, changing proportions, labels, dimensions, people,
logo, watermark, or camera cut.
