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.

About Seedance 2.5 · 30s

Seedance 2.5 · 30s is the long-form tier of ByteDance's Seedance 2.5, and what sets it apart from the other Seedance models here is the billing shape: it is priced PER CLIP, a flat $1.50 for one 30-second 720P render. Aspect ratios 16:9 / 9:16 / 1:1 / 4:3 / 3:4, up to 9 reference images; omit them for text-to-video, include them for image-to-video. The finished clip carries a native soundtrack. Async job: POST /v1/videos/generations returns HTTP 202 and a job id immediately; poll GET /v1/videos/jobs/{id} until status=succeeded and read data[0].url -- an mp4 re-hosted by us and kept for 60 days (download it before then). Renders take about 15-20 minutes, so poll rather than waiting synchronously.

Use cases

A complete story in one take

30 seconds is enough for a product story or a concept piece, and you never have to cut it short to save money.

Long-form commerce video

Showing a product from several angles usually runs past 20 seconds -- exactly the range a per-second price punishes.

Vertical short-form

9:16 is verified to return a 720x1280 portrait clip, ready to hand straight to a short-video platform.

Image-to-video continuity

Up to 9 reference images, good for animating product or scene shots while keeping them consistent.

How to choose

Pick it when you want a 30-second clip: the same 30 seconds costs $4.74 on the per-second seedance-2.5 and $1.50 here. If you need to choose the duration (4-30s), 480P, an audio switch or reference audio/video, use seedance-2.5; for a few seconds only, the per-second seedance-2.0 is cheaper; and when budget comes first, grok-imagine-video-1.5 starts at $0.30.

FAQ

Can I ask for 10 seconds?

No. This tier is fixed at 30 seconds -- the upstream renders 30 whatever you send and charges the same for it. So we reject other durations at submit rather than charging you for 30 seconds and handing back a clip you did not ask for. Use seedance-2.5 when you need to pick the length.

How does it compare with the per-second seedance-2.5?

This model is a flat $1.50; seedance-2.5 is $0.158 per second. The crossover sits near 9.5 seconds -- below that the per-second model wins, and for a 30-second clip this one is 68% cheaper.

Does it handle real people?

Not guaranteed. The upstream marks this tier face-restricted, so reference images with real people may be rejected by its review. A rejection refunds in full, but if your material is people-first, use seedance-2.5 instead.

Does the clip have sound?

Yes -- renders come back with a native AAC stereo track and no extra parameter is needed. Because there is no switch for it upstream, this model does not accept an audio parameter.

How long does it take?

About 15-20 minutes in testing. Poll the async job rather than waiting synchronously. A timeout or failure refunds in full.
