AI video generation just entered a new era. Seedance 2.0 from ByteDance is now available on Visualizee.ai - and it delivers a massive leap in motion quality, physical accuracy, and audio. Upload your start frame (and optionally an end frame), describe the motion you want, and Seedance 2.0 produces coherent, physically accurate video with synchronized dual-channel stereo audio.
This is available today for Pro and Max plan subscribers. Here's what it brings to your workflow:
Start frame + end frame control - define the opening and closing shot, and the AI generates smooth motion between them
15-second videos with dual-channel stereo audio generated automatically
Physically accurate motion - complex interactions that follow real-world physics
Immersive audio - foley details, ambient sounds, and background music synchronized to the visuals
Why Seedance 2.0 Matters
Previous image-to-video models often produce motion that looks artificial - floating objects, impossible body mechanics, and physics that break the illusion. Seedance 2.0 solves this with a unified architecture that understands how the real world moves. Combined with start/end frame control and automatic stereo audio, it turns your still renders into production-quality video.
For architects, designers, and creative professionals, the workflow is straightforward: generate or upload your render, set it as the start frame, optionally provide an end frame to define where the camera lands, describe the motion and atmosphere, and Seedance 2.0 handles the rest - including immersive stereo audio.
Key Capabilities
Start Frame + End Frame Control
Define exactly where your video begins and ends. Upload a start frame (required) and an optional end frame, and Seedance 2.0 generates smooth, coherent motion between the two. This gives you precise control over:
Architectural transitions - start at the entrance, end at the living room window
Time-of-day shifts - begin at golden hour, end at blue hour
Reveal sequences - open on a detail shot, close on the full space
Before/after transformations - show a room furnished vs. empty
When you provide only a start frame, describe the camera movement and Seedance 2.0 determines the natural endpoint.
Physically Accurate Complex Motion
Seedance 2.0 delivers a significant leap in motion quality. Multi-subject interactions, complex movements, and subtle physics all render naturally - no more floating objects or impossible body mechanics.
The model handles scenarios that previous generators couldn't:
Multi-person interactions - handshakes, group activities, collaborative work
Precise physical motion - fabric draping with gravity, water splashing realistically, objects falling naturally
Continuous action sequences - a person walking through a door, sitting down, and picking up an object
Dual-Channel Stereo Audio
Seedance 2.0 generates dual-channel stereo audio synchronized with the visual content. It supports multi-track parallel output for background music, ambient sound effects, and character voiceovers - all aligned with the visual rhythm.
The audio quality extends to subtle foley details: the scratch of frosted glass, rustling fabric, gentle tapping on surfaces, or the popping of bubble wrap. Paired with precise audio-visual timing, this creates an immersive viewing experience without any post-production sound design.

Demo: Creating a 12-Second Walkthrough with Audio
Here's a practical example of what Seedance 2.0 can produce on Visualizee.ai. We'll turn a single architectural render into a 12-second cinematic walkthrough with synchronized stereo audio.
Step 1: Generate the First Frame
Start by creating the still image that will serve as the opening shot. You can generate this in Visualizee.ai or upload your own render.
Step 2: Generate the Video with Motion and Audio
Use the first frame as the start image in Seedance 2.0 and describe the camera movement and audio you want.
Settings:
Duration: 12 seconds
Start image: The first frame generated above
Audio: Enabled
Model: Seedance 2.0
Step 3: Review the Result
The generated video should show a smooth, cinematic camera movement from the hallway into the living space, with realistic curtain movement, shifting light, and coherent material detail throughout. The dual-channel audio will include ambient city atmosphere, subtle wind, and soft background music - all generated automatically.
Pro Tip: Want more control? Provide both a start frame and an end frame - for example, the hallway shot above as the start and a close-up of the city skyline through the window as the end. Seedance 2.0 generates smooth motion between the two.
How to Use Seedance 2.0 on Visualizee.ai
Image-to-Video: Bring Your Renders to Life
The core workflow - upload a render or photo, describe the motion you want, and Seedance 2.0 animates it while preserving every visual detail and generating synchronized audio.
Example with Vizzy:
You: Uploads a render of a modern courtyard house at golden hour. "Animate this with a 10-second slow dolly forward through the entrance into the open-air garden. Include ambient water sounds from the reflecting pool and soft wind."
Vizzy: "I'll animate your render with Seedance 2.0. The camera will dolly forward through the entrance, revealing the courtyard garden and reflecting pool. Audio will include water trickling and gentle wind. Generating now..."
Example workflow:
Generate a still render in Visualizee.ai or upload your own image
Tell Vizzy: "Animate this with a slow pan to the right, add gentle curtain movement and ambient room sounds"
Seedance 2.0 creates the video with matching audio
Start + End Frame: Direct Your Scene
For maximum creative control, provide both a start frame and an end frame. Seedance 2.0 generates smooth, coherent motion between the two shots.
Example with Vizzy:
You: Uploads two renders. "Use the first image as the start frame and the second as the end frame. Create an 8-second smooth dolly forward from the entrance to the window view. Add ambient interior sounds."
Vizzy: "I'll generate an 8-second video that transitions from the entrance shot to the window view with a smooth dolly forward. Seedance 2.0 will handle the motion path and generate ambient audio. Generating now..."

Use Cases for Design Professionals
Architectural Walkthroughs with Sound
Create complete spatial experiences: the camera moves through the space while water features trickle, footsteps echo on polished concrete, and ambient sounds bring the scene to life. Upload your still render as the start frame, optionally set an end frame, and describe the motion.
Interior Design Client Presentations
Show clients material and lighting options as video - far more impactful than static renders. Generate different versions from the same start frame with different prompts to compare design directions side by side.
Product Reveal Videos
Upload a product photo as the start frame, set a different angle as the end frame, and describe the reveal. Seedance 2.0 handles the camera movement, lighting transitions, and audio synchronization in one generation.
Real Estate Marketing
Generate property tour videos with spatial audio that give buyers an immersive preview. Use start and end frames to control exactly which spaces the camera reveals. Explore AI tools for real estate.
Social Media Content
Create scroll-stopping video content with built-in audio - no separate sound editing needed. The 15-second duration is ideal for Instagram Reels, TikTok, and YouTube Shorts. See marketing solutions.
Best Practices
Writing Effective Motion Prompts
Be specific about camera movement, timing, and atmosphere:
Describe the path: "Slow dolly forward from the hallway into the living room, drifting slightly left toward the window"
Include timing cues: "The camera pauses briefly at the fireplace before continuing toward the balcony"
Add atmosphere: "Golden hour light shifts across the floor as the perspective changes, subtle dust particles in the beams"
Getting the Best Audio
Include environmental cues in your text prompt for richer sound design:
Mention specific materials - "footsteps on marble," "rain on glass," "wind through leaves"
