Seedance 1.5 Pro is ByteDance’s high-quality AI video model for generating short, cinematic video clips from text or images, with optional native audio.
It’s perfect for creators who want smooth motion, consistent visuals, and tight audio-sync without spending hours compositing or searching for workaround tools. You work in 4 to 12-second clips, then chain them manually to build narrative flow.
If you’re producing storytelling content, marketing visuals, talking-head moments, or concept-driven video, Seedance 1.5 Pro gives you a reliable technical base with fewer surprises and more control over how a shot begins and ends.

What is Seedance 1.5 Pro best at?
Understanding Seedance 1.5’s core strengths will help you to decide when to choose this model for your projects. Here’s what it excels at:
Visual consistency across shots
The Seedance 1.5 Pro AI video generator model maintains strong subject and style consistency across generation iterations. If you reuse prompts, repeat character descriptions, and feed select still frames into the next generation, you can build multi-shot sequences with a coherent look and feel.
For everything from product showcases to character-driven storytelling, that consistency saves time and keeps your edit clean.
Start and end frame control
Seedance 1.5 Pro supports image-based references to start and end your videos with. You can lock in:
- how a shot opens
- how it closes
- the exact frames you want to transition between
This works particularly well when you want match cuts, motion continuity, or visual anchors in a multi-shot workflow.
From a still image, Start Frame, and the text prompt below, we created this video in seconds. The result could work perfectly for a UGC or product brand campaign.
Prompt: The camera makes a smooth circular movement around the table, slowly orbiting the scene. As the camera moves, sunlight pours onto the perfume bottle, causing its reflections to dance and shimmer across the pastel table surface. The motion feels cinematic, elegant, and fluid.
Strong audio-visual sync
Seedance 1.5 Pro generates audio and video at the same time. That means lip-sync accuracy, sound effects tied to movement, and audio that matches the environment. The model handles the sync for you, as long as the sound you want is described clearly in your prompt. As a creator, it’s important to note that you can’t position specific sound cues at exact timecodes. If you need detailed mixing, you’ll still do it in post.
And for projects that need a silent movie, you can turn off the audio using the toggle in the Artlist Toolkit settings.
Native multilingual lip-sync
The model handles diverse languages and dialects, which makes it a powerful tool for global creators or brands producing content in multiple markets. Dialogue feels more grounded and less mechanical.
What projects should you use Seedance 1.5 Pro for?
Some of the best use cases for this video model include:
Short narrative and storytelling: You can create emotional beats, character moments, and scene transitions in tight 4 to 12-second clips. Add dialogue or sound cues directly in the prompt, then chain the clips for longer stories.
Storyboard and previsualization: Turn written scripts or still frames into rough sequences with camera motion and ambient sound. It’s useful for planning edits, scoping visuals, or pitching concepts before production.
Talking-head and avatar content: Use it for expressive avatar videos, virtual presenters, or character commentary. Multilingual lip-sync makes it easier to localize your content without re-recording.
How to write better prompts for Seedance 1.5 Pro
1. Describe audio intent directly
Spell out what you want the model to generate. For example:
- “A woman whispers, ‘We’ll find it,’ as wind brushes through trees.”
- “Footsteps echo on concrete, slow and heavy.”
- “Soft ambient synth rises as the camera pushes in.”
The model responds well when you name dialogue, ambience, and sound effects clearly. Check out this example we created with AI Video on Artlist.
Prompt: A young woman in a tattered cloak whispers, ‘We’ll find it,’ as wind brushes through a dense, misty forest. Leaves rustle and small branches snap underfoot. The camera slowly tracks her from behind, following her steps on a moss-covered path, then pans slightly to reveal flickering light through the trees. Her breath is visible in the cold air. A distant owl hoots, and soft, suspenseful ambient synth rises in the background. Her eyes widen as she glances at a hidden stone doorway partially covered in ivy. The video ends with a subtle zoom on the carved symbols glowing faintly on the door, wind and ambient sound continuing, creating tension and mystery. Cinematic lighting with soft shafts of golden sun breaking through mist.
Start Frame: a close-up of her boots on the mossy ground
End frame: the glowing doorway.
2. Treat each clip as its own shot
Because the workflow is sequential, structure prompts like you’re writing shot descriptions, such as “Wide shot of a foggy forest path…”, “Cut to a close-up of the character’s hand holding a compass…” or “Low-angle tracking shot moving toward the doorway…” Consistent naming of characters, objects, and environments helps the model carry continuity into the next video.
3. Think in time
Describe how the shot evolves:
- camera movement
- action within the frame
- transitions between states
- emotional shifts
- sound changes
The more precise you are about progression, the smoother the motion and pacing will feel.
