Input

Prompt

"Beneath the Walls of Troy" - a 30-second epic action commercial. @Image1 is a Greek hero in a golden bronze breastplate and crimson cloak, wearing a red-crested Corinthian helmet, armed with a long spear and a lion-emblem round shield; @Image2 is a Trojan champion in blackened scale armour and a royal-blue cloak, wearing a black-crested helmet, armed with a curved sword and a horse-emblem round shield; the setting follows the walls of Troy and the sunset battlefield of @Image3. Keep each warrior's armour, helmet, cloak colour, weapon and shield emblem exactly as in their own reference for the whole clip - never swap them. The final second must be black with gold English text "Made with NezhaGate". The ending must be a handshake and a salute between the two; nobody is left lying on the ground.

0-3s: Sunset. An aerial shot sweeps past the colossal walls of @Image3, wind driving the sand; in the middle of the field the two warriors face each other twenty paces apart, drums rumbling low.
3-6s: Alternating close-ups: the sharp eyes of @Image1 behind the helmet's slit; the fingers of @Image2 tightening one by one around the sword grip; grains of sand hopping on the ground with each drumbeat.
6-10s: Both charge at once, a low tracking shot, sand exploding under their feet; @Image1 hurls the spear, @Image2 raises the shield - the spear point strikes it in a burst of sparks, splinters of wood and bronze scattering in slow motion.
10-15s: Close combat: @Image2 lands three rapid slashes, @Image1 blocks with the shield and sidesteps, a trail of sparks scraping off the shield rim; the camera orbits the pair a full 360 degrees - fast, fluid, powerful.
15-20s: @Image2 rams forward and drives @Image1 back against a toppled chariot, the sword biting into the wooden spokes of its wheel; @Image1 vaults over the chariot, rolls on landing and snatches up a broken spear from the sand.
20-25s: Climax: the setting sun sits right between them; @Image1 leaps into the air, @Image2 raises the shield to meet him, and they clash mid-air - the shot drops into extreme slow motion, sparks, sand and the flying crimson cloak hanging in the air as a shockwave pushes the dust into a ring.
25-29s: On landing @Image2 falls to one knee, the shield rolling away; @Image1 lowers the broken spear, pauses a beat and offers his hand; @Image2 takes it and rises, and the two warriors salute each other in a haze of golden dust.
29-30s (final second only): Cut to black; a single line of bright gold serif text appears at center: "Made with NezhaGate", about one third of the frame width, crisp and sharp, with one deep drum resonance.

Action and performance: the fight is continuous, fast and weighty, attacks and defences easy to read, every impact with recoil and body sway; tightening grips, hard breathing, locked eyes and the final salute must be visible; both warriors keep their helmets on.
Camera: top-tier cinematic action commercial, 24fps film look, widescreen; aerial, low tracking, 360-degree orbit and extreme slow motion alternating, brief slow motion on key impacts; no shaky handheld, no cutting so fast the action becomes unreadable.
Environment: wind-blown sand, sparks, splinters, flowing cloaks and crests, and the dusty haze against the low sun all move with real physics.
Sound: war drums, wind, metal and shield impacts, feet in the sand, creaking armour, hard breathing; an epic orchestral score building up, key impacts landing on the beat.
Avoid: blood, wounds or death; extra characters; any on-screen text, captions or watermarks except "Made with NezhaGate" in the final second; weapons or shields merging or swapping; deformed fingers or limbs; confusing the two warriors.

Content requirements

Full details →

Everything is reviewed
The prompt, the reference files and the finished clip all go through content review, picture and sound alike.
No charge if rejected
A rejected job is not charged; the credits held at submit are refunded in full.
The finished clip is reviewed again
Some jobs are rejected at submit; others only when the finished clip is reviewed, anywhere from a few minutes to over half an hour later.
Sound is reviewed too
Spoken lines, narration and lyrics in your prompt are voiced or sung, and reviewed together with the picture. If you need no voices, leave out lines and lyrics. This model always adds a soundtrack; it cannot be turned off. Uploaded reference audio is reviewed as well.
Commonly rejected
Sexual content or nudity; gore, self-harm and violent injury such as gunshot wounds; firearms, explosives and drugs; minors shown with alcohol, tobacco or in danger; politicians, celebrities and other public figures, in looks or voice (look-alikes included); copyrighted characters.
One bad shot fails the whole clip
If a single shot in a long storyboard script breaks the rules, the whole clip is rejected. Resubmitting the same input is rejected again; fix that part or replace the reference, then retry.
