Video model by ByteDance Seed

Seedance 2.5

ByteDance's newest video model makes 30 seconds of video with sound in a single take, which is enough room for a whole ad to play out from hook to payoff. Every clip on this page shows the exact prompt behind it, so you can borrow what works and swap in your product.

Made with Seedance 2.5

The prompt

One continuous shot, no cuts. Photoreal, 35mm, smooth gimbal tracking, dusk after monsoon rain, wet reflective surfaces, saffron and deep green palette. [0-5s] On a wet rooftop, a child's hand releases a folded paper airplane. The camera follows just behind it as it lifts into the wind. Sound: wind, distant traffic. [5-11s] The plane dives between buildings and skims over a crowded vegetable market, past hanging marigold garlands. Sound: vendors calling, oil sizzling. [11-18s] It slips through the open window of a moving commuter train. Passengers, ceiling fans spinning. Sound: rhythmic train clatter. [18-25s] It exits the far window, glides across a schoolyard and through a classroom door. Sound: chatter fading to quiet. [25-30s] It lands on a wooden desk. A hand unfolds it to reveal a crayon drawing of the same rooftop. Camera settles close. Sound: paper rustle, distant thunder.

One take

30 seconds, no cuts

Seedance 2.0 stopped at 15 seconds, so anything longer meant stitching clips that never quite matched. This one holds a single shot for the full 30, and you can watch each line of the prompt land on screen.

Seedance 2.0 vs 2.5

What changed from Seedance 2.0

The prompt on bothOne continuous take, warm documentary look, small café in morning light. A barista grinds beans, tamps, pulls an espresso shot, steams milk and pours a leaf of latte art. Continuous close tracking. Sound: grinder, steam wand, café ambience.

References

Your references, your ad

Hand it a product photo, a character, a motion clip and a track, and say what each one is for. It takes up to 50 references at once, which is how an ad ends up looking like your brand instead of stock footage.

Hover a reference to see where it shows up.Tap a reference to see where it shows up.

The result

A vertical sneaker ad built from 4 references: an invented skater, a product photo, a skate-trick clip and a music track.

Timestamp edits

Change one moment, keep the rest

Point at a timestamp and say what should change. Everything before and after stays put, so a wrong jacket color no longer costs you the whole take.

Limits

Where it struggles

Every model has weak spots, and these come from ByteDance's own notes and from people using it for real work. Knowing them up front saves you credits.

Fast action

Quick, complex movement can morph or wobble, and upscaling won't clean it up.

FixSlow the action down in your prompt, or try a model built for action.

Characters interacting

With several people touching or reacting to each other, gestures can come out wrong.

FixSpell out exactly who does what to whom.

Resolution

There's no 4K, and most platforms top out at 720p.

FixNeed 4K? Seedance 2.0 makes it, for clips up to 15 seconds.

Voices

It guesses a voice from your references and sometimes adds an accent you didn't ask for.

FixName the voice and accent in plain words in your prompt.

Old prompts

Prompts written for Seedance 2.0 can glitch here, and rapid one-second cuts tend to fall apart.

FixWrite fewer, longer beats and let each one breathe.

Retries

A good take often needs a few attempts, and each 30-second attempt costs similar credits.

FixDraft on Seedance 2.0, then switch to 2.5 for the final take.

Real faces

Real people's faces, selfies included, are reportedly blocked.

FixUse invented characters.

    02

    Write it in beats

    Split your 30 seconds into 4 or 5 moments, and for each one say what we see, what the camera does and what we hear. Give every reference a job, like "Image 1 is the product."

  3. A finished Seedance 2.5 video: a paper plane over a rooftop at sunset

    Make it, then fix what's off.

    If one moment is wrong, edit that moment instead of starting over.

A prompt written like a storyboard works better than one long paragraph. Here's the shape we start from.

[The look: lens, light, palette, one shot or several]

0-6s: [What we see]. Camera: [move]. Sound: [what we hear].
6-12s: [What we see]. Camera: [move]. Sound: [what we hear].
12-20s: [Your product appears]. Camera: [move]. Sound: [what we hear].
20-30s: [How it ends]. Camera: [move]. Sound: [what we hear].

References: Image 1 is [the product]. Image 2 is [the character]. Audio 1 is [the track].

No. Most platforms, Predis.ai included, offer up to 1080p, and Seedance 2.0 is the version with 4K.

It doubles the longest clip from 15 to 30 seconds and takes far more references. Seedance 2.0 still has 4K and usually costs less for short clips.
