Seedance 2.0
ByteDance
#1 Image-to-Video with Audio — Multimodal Reference System
Seedance 2.0's core advantage is its reference input system: upload up to nine images to anchor appearance, three video clips to guide camera movement and action, and three audio clips to set sound atmosphere — all processed in a single generation pass alongside your text prompt. The Dual-Branch Diffusion Transformer generates video and audio simultaneously, producing synchronized dialogue, ambient sound, and music without a separate audio step. Ranked #1 on Artificial Analysis for image-to-video with audio.
- #1 on Artificial Analysis — I2V with Audio
- 9 reference images + 3 video + 3 audio clips
- Native audio-video joint generation
- Multi-shot scene sequencing
Wan 2.6
Wan AI
Character Consistency Across Scene Cuts
Wan 2.6 maintains consistent character appearance across multiple sequential clips — the same face, clothing, and visual identity carries through every shot without the identity drift that appears when re-generating characters with other engines. Audio locks continuously across all shots: dialogue, ambient, and foley layers do not break at edit points. The right engine for multi-scene narratives and serialized content.
- Consistent character identity across cuts
- Continuous audio across multi-shot sequences
- Image-to-video with style consistency
- 5–15s output
How Seedance 2.0 Generates Audio and Video Together
Most AI video models produce silent video first, then layer audio on top in a separate step. Seedance 2.0 works differently: its Dual-Branch Diffusion Transformer architecture processes audio and video as parallel streams from the same prompt. Dialogue, environmental ambient sound, and background music emerge from the same generation step as the visual frames — with timing anchored to the motion rather than synced after the fact. The result is tighter alignment between what is seen and what is heard, without manual audio editing or offset correction.
What Creators Use Seedance 2.0 For on Bytedance Seedance
From social content to brand campaigns — six use cases where Seedance 2.0's reference system and native audio deliver results other engines cannot match.
Short-Form Social Content
Vertical 9:16 with native audio — ready for TikTok and Reels
Generate 9:16 vertical video with audio already embedded for direct upload to TikTok, Instagram Reels, or YouTube Shorts. Upload a reference image to anchor your subject's appearance, write the scene description, and Seedance 2.0 handles motion, dialogue, and background audio in one pass. No video editor, no audio sync step, no export workflow.
Brand Campaigns with Reference Control
Lock brand visuals across every video with reference image anchoring
Upload product photos, brand assets, or visual identity references as @Image inputs to anchor Seedance 2.0's output to your specific visual language. Generate product reveal videos, lifestyle campaign clips, or brand story sequences where the visual identity stays consistent across every generation — without rebuilding the shot from scratch each time.
Animate Reference Images into Motion
Turn any still image into a fluid scene with accurate body motion
Upload a character illustration, product photo, or concept art and Seedance 2.0 animates it with physically plausible motion — cloth reacting to movement, weight transferring naturally, environmental elements responding to action. Supply a reference video clip to guide the specific motion style: choreography, athletic movement, or camera behavior can all be templated from a reference.
Pre-Production and Storyboard Visualization
Turn scene descriptions into visual reference in minutes, not days
Translate script descriptions into visual reference clips for director presentations, client approvals, and production planning. Upload location reference photos as @Image inputs, supply a camera movement reference as @Video, and describe the action — Seedance 2.0 generates a visualization that communicates framing, timing, and atmosphere without a full production crew.
Educational and Training Video at Scale
Describe the concept and get a watchable explainer in one prompt
Generate instructional video sequences from text descriptions of concepts, processes, or procedures. Supply relevant visual references to anchor the learning material to specific equipment, environments, or scenarios. Audio narration and sound cues generate alongside the visual, producing a complete instructional clip without recording, editing, or animation software.
Game Cinematic and Concept Visualization
From asset references to cinematic sequences — without a render farm
Upload character concept art, environment designs, or in-game screenshots as reference inputs. Describe the scene narrative, camera angles, and action beats. Seedance 2.0 generates cinematic sequences that visualize gameplay moments, story beats, and trailer concepts with production-quality motion and sound — usable for pitch decks, promotional material, and development reference.

Seedance 2.0 Prompt Examples — Reference-Led and Text-Only
Effective Seedance 2.0 prompts separate what should come from reference files versus what should come from text. These examples show both approaches.
Vertical Social Content
Fashion brand, 9:16 for TikTok or Instagram Reels
"A model in a white linen dress walks through a sunlit courtyard. Camera follows at shoulder height, slight handheld drift. Light summer breeze, fabric moving naturally. Natural ambient sound — footsteps on stone, birds, distant fountain. 9:16 vertical, 8 seconds."
Product Reveal with Reference Anchor
Upload product photo as @Image1 reference
"@Image1 product rotates slowly on a dark slate surface. Studio lighting from upper left with soft fill. Chrome reflection on the base. Subtle ambient sound — low drone, clean room silence. 16:9, 6 seconds."
Cinematic Scene Visualization
Pre-production storyboard — upload location reference as @Image1
"Wide establishing shot of @Image1 at dusk. Camera slowly pushes in, holding horizon line. One figure visible in the mid-distance, facing away. Wind moving through tall grass. No dialogue. Ambient environmental sound — wind, rustling, distant birds. Cinematic 2.39:1, 10 seconds."
Instructional Sequence with Narration Cue
Process explanation — text-only, no reference needed
"Close-up of hands carefully folding a paper crane, step by step. Camera stays focused on the hands, clean white surface below. Narrator says: "Begin by folding corner to corner, creating a triangle." Calm background music. 16:9, 12 seconds."
Four techniques that consistently improve Seedance 2.0 output:
- • Separate reference and text jobs - Use @Image references for appearance — face, clothing, environment. Use @Video references for motion style and camera behavior. Let text handle narrative and audio description. Mixing all three in text alone produces weaker results.
- • Name audio explicitly - Write audio as direction, not mood. "Narrator says: [text]" or "a car door closes" or "rain on a metal roof" produces accurate audio. "Dramatic atmosphere" or "cinematic sound" produces generic output.
- • Specify camera movement with cinematography terms - "Slow dolly in", "steadicam follow", "rack focus from foreground to background", "static wide" — these terms are understood and followed. Vague direction like "move the camera" produces inconsistent results.
- • End with format and duration - Close every prompt with the target format — "9:16 vertical, 8 seconds" or "16:9 cinematic, 10 seconds". Seedance 2.0 uses this to correctly frame composition and pacing.
