Seedance 2.5 Tips
- • Seedance 2.5 is a director, not a search engine — write a shot brief, not a description
- • Real cuts come from explicit "cut to" or "Shot 1: / Shot 2:" labels — bare timestamps only set pacing inside one continuous take
- • One action + one camera move per shot; stacking camera moves muddies the motion
- • Wrap dialogue in double quotes with a tone note and keep lines short: she softly whispers "I am free"
- • For image-to-video: describe motion and camera only — the model already sees your image
- • Reference-to-video takes up to 50 assets (images, video, audio, 3D white-box) — give every @Image1 / @Audio1 an explicit role
- • Edits and extensions must open with the action word the API looks for: "Replace...", "Remove...", "Add..." for edits, "Extend @Video1 forward / backward" or "Continue the story" for extensions
- • Lens type + shallow DOF steer the look more than camera-body names; always close with the spec line (resolution, aspect ratio, duration, fps)

Multi-Reference Generation
TechniqueSeedance 2.5 accepts up to 50 multimodal references — assign roles.
Reference 1 (character): preserve this person's face, hair and build exactly. Reference 2 (wardrobe): the outfit and its materials. Reference 3 (environment): the location and its light. Reference 4 (style): match this grade and grain. Generate: [CHARACTER] [ACTION] in the referenced environment. Camera: [MOVE]. Duration: [SECONDS] seconds at [RESOLUTION]. Audio: [SOUND].
Long-Form Single Take
CinematicUses Seedance's native single-pass clips up to 30 seconds.
A single continuous [SECONDS]-second take, no cuts. 0-[X]s: [WHAT HAPPENS]. Camera [BEHAVIOUR]. [X]-[Y]s: [WHAT HAPPENS]. Camera [BEHAVIOUR]. [Y]-[END]s: [WHAT HAPPENS]. Camera [BEHAVIOUR]. [SUBJECT] stays consistent throughout. Lighting: [SETUP]. Grade: [GRADE]. Output [RESOLUTION], 10-bit colour.
Synchronised Dialogue Scene
AudioAudio generated in the same latent space as picture.
[CHARACTER A — description] and [CHARACTER B — description] in [SETTING]. A says: "[LINE]" B replies: "[LINE]" Voices: A is [VOICE]; B is [VOICE]. Lip-sync must match. Ambient: [BACKGROUND SOUND]. Music: [MUSIC OR NONE]. Camera: [FRAMING — e.g. over-the-shoulder favouring A, then reverse]. Lighting: [SETUP]. Duration: [SECONDS] seconds.
Region-Level Edit
EditingSwap a subject, product or background without re-rendering the shot.
In the supplied video, replace [WHAT — e.g. the product held in frame] with [NEW ELEMENT]. Keep everything else identical: the camera move, the actor's performance, the lighting, the shadows, the background and the audio. Match the replacement's scale, perspective and light response to the original shot across every frame.
1080p Product Film
CommercialFull-HD commercial output with sound design.
[PRODUCT] in [SETTING]. [MATERIAL AND FINISH DETAIL]. Camera: [MOVE] on a [LENS], constant speed. Lighting: [SETUP], with [WHAT THE LIGHT DOES ON THE MATERIAL]. Audio: [SOUND DESIGN — e.g. a low ambient pad with one crisp mechanical click on the reveal]. Render: 1080p, [ASPECT RATIO], [GRADE], [SECONDS] seconds, 24fps.
3D Reference Shot
TechniqueSeedance accepts 3D white-box references for exact staging.
Using the supplied 3D white-box reference for camera path and scene layout, render: [FULL SCENE DESCRIPTION]. Follow the reference's camera move and object placement exactly.

How to Use the Prompt Generator
Pick Mode & Direct Your Shot
Choose Text-to-Video, Image-to-Video, Reference-to-Video, or Region Edit. Pick a use case (cinematic, music video, lip-sync dialogue, multi-shot), set resolution and audio mode, and write your action as a shot list — use explicit "cut to" or "Shot 1: / Shot 2:" labels for real cuts, and timestamps like [0-3s] to pace the beats.
Generate Your Prompt
Click Generate. The tool assembles a director-style brief — subject + action with labeled shot cuts, camera movement, lens and look direction, color grading palette, audio direction with quoted dialogue, and the technical spec close-out (resolution, aspect ratio, duration, fps).
Copy & Generate
Paste into Dreamina, Jimeng, or the ByteDance Volcano Engine API (the prompt also runs on Seedance 2.0 and other top video models). Draft at 480p first to iterate cheaply, then re-render the winner at 1080p.
Frequently Asked Questions
What is Seedance 2.5?
Seedance 2.5 is ByteDance's latest multimodal AI video model, unveiled June 2026 at the Volcano Engine FORCE conference. It generates native single-pass clips up to 30 seconds long at up to 1080p on the public API, accepts up to 50 multimodal references in a single job (images, video, audio, style boards, and 3D white-box models), produces synchronized audio in the same generation, and adds localized region-level editing. It rolls out through ByteDance's Dreamina and Jimeng apps and the Volcano Engine API. A separate Seedance 2.5 4K version (10-bit color) launched October 23, 2026, but only for selected enterprise film studios.
How does this prompt generator work?
You provide structured inputs — scene, action, camera movement, audio, color grading, camera/lens look, and shot structure (single or multi-shot). Our AI applies Seedance's director-style framework: Subject + Action → Environment → Look → Camera → Audio, and always closes with the technical spec line (resolution, aspect ratio, duration, fps).
What changed from Seedance 2.0 to Seedance 2.5?
The headline upgrades: native 30-second single-pass generation (up from ~4–15s, and no stitching), a 480p draft mode for cheap previews, up to 50 multimodal references (up from 12) including 3D white-box models, localized region-level editing that swaps a subject, product, or background without re-rendering the whole shot, dedicated edit and forward or backward extension tasks in the API, 11 officially supported dialogue languages, and ByteDance-reported gains in prompt adherence and audio-visual sync. Native audio, lip-sync, multilingual dialogue, director-level camera control, and the @Image / @Video / @Audio reference syntax carry over from 2.0.
Do timestamps create hard cuts in Seedance?
Not on their own — this is the most common misconception. Timestamps like [0-3s] / [3-10s] set pacing and progression WITHIN a single continuous take (when things happen), not editorial cuts. To get real cuts inside one generation you must label them explicitly with "cut to …" or numbered "Shot 1: … Shot 2: …" markers; the model reliably follows about five to six labeled shots while keeping characters and style consistent. Use timestamps for rhythm, cut labels for cuts.
How do I get accurate lip-sync and dialogue?
Wrap spoken lines in double quotes and describe the tone in plain language before the line — for example, she softly whispers "just looking at you". Keep each line short (long monologues drift out of sync — split them across shots). There is no bracketed [emotion] markup; natural-language tone direction is what works. Seedance 2.5 officially supports 11 languages (Chinese, English, Spanish, Indonesian, Malay, Thai, Arabic, Portuguese, Vietnamese, Japanese and Korean), so name the target language if it is not English.
Does naming a specific camera or lens actually change the look?
Lens type and optics language genuinely steer the image — "wide lens," "telephoto," "shallow depth of field, f/1.8," "anamorphic flare" change framing and focus. Naming a specific camera body like Sony Venice or ARRI Alexa works more as a film-look style keyword (nudging color science, grain, and flare) than as literal hardware simulation. Both help, but describe the optics and lighting you want rather than leaning on gear names alone — that beats generic tags like "8K" or "cinematic."
What's the difference between Text-to-Video, Image-to-Video, Reference-to-Video, and Region Edit?
Text-to-Video generates from the prompt alone — most flexible. Image-to-Video animates an uploaded still — describe motion and camera only, not the visuals (the model already sees the image). Reference-to-Video accepts up to 50 assets (images, video, audio, style boards, 3D white-box models) referenced via @Image1 / @Video1 / @Audio1 syntax, and every reference should be given an explicit role for character consistency, style transfer, and beat-matched cuts. Region Edit changes a localized area — swap a subject, product, or background — while preserving the rest of the shot's motion, camera, and lighting.
What resolutions and durations does Seedance 2.5 support?
Seedance 2.5 renders native single-pass clips of 4 to 30 seconds at 480p, 720p (8-bit) or 1080p (10-bit), 24fps, on the public BytePlus API, and a 480p draft mode lets you preview cheaply. The API also has first/last-frame, edit and extend tasks (edit and extend take an uploaded 4 to 30 second clip, and extension can run forward or backward); those tasks keep the source's aspect ratio. Aspect ratios include 16:9, 9:16, 1:1, 4:3, 3:4, and 21:9. Seedance 2.5 4K, with 10-bit color, launched October 23, 2026 for a small group of enterprise studios only, with no public API yet.
Does Seedance 2.5 support audio?
Yes — it is one of the few models with native audio-visual joint generation, and 2.5 processes audio in the same latent space as the video for tighter sync across the full 30-second take. It can generate lip-synced dialogue, an emotion-matched music score, and diegetic sound effects in a single pass, or choreograph the video to match a reference audio track. Direct sound explicitly, and say "no music" when you don't want a score — open prompts tend to come back over-scored.
