Chrome ExtensionSeedance 2.5 Video Prompt Generator
Generate optimized video prompts for ByteDance's Seedance 2.5 — the multimodal model with native 30-second single-pass clips, up to native 4K, synchronized audio, up to 50 references (text + image + audio + video + 3D white-box in one pass), and localized region-level editing. Built around the director-style framework: Subject + Action → Environment → Look → Camera → Audio, with explicit multi-shot cut labels and lens-driven look direction baked in.
Describe the main visual scene — subjects, environment, mood, and key visual details

Fill in the form and click "Generate" to create an optimized Seedance 2.5 video prompt.
Tip: Describe the motion and temporal progression of your scene. Think in terms of "what happens over time" rather than a static description.
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
- • Lens type + shallow DOF steer the look more than camera-body names; always close with the spec line (resolution, aspect ratio, duration, fps)
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). For 4K hero shots, draft at 720p first to iterate cheaply, then re-render the winner.
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 native 4K (10-bit color), 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.
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), native 4K with 10-bit color, 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, and roughly 20% better prompt adherence with tighter 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 handles multilingual dialogue (English, Mandarin, Japanese, Korean, Spanish, and more) — 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 up to 30 seconds at up to native 4K (10-bit color), with 720p and 1080p available for faster, cheaper drafts. Aspect ratios include 16:9, 9:16, 1:1, 4:3, 3:4, and 21:9. Draft at 720p to iterate cheaply, then re-render your winner at 4K.
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.
