What Seedance 1.5 Pro does well
The strengths worth knowing before you write your first prompt.
Multilingual lip-sync
Write a line in quotes, in English, Spanish, Japanese or many other languages, and the character says it with mouth movement that matches the words.
Joint audio and video
Voice, effects and room tone are generated with the picture, not added later, so timing and space feel natural. Audio is on by default.
First and last frame
Bring your own character in as a first frame and set where the scene ends with a last frame. Great for spokespeople and recurring hosts.
4 to 12 second scenes
Choose 4, 5, 8, 10 or 12 seconds. That is room for a hook, a short exchange or a full product line.
Every format
Render in 16:9, 9:16, 1:1, 4:3, 3:4 or 21:9, at 480p, 720p or 1080p, for feeds, stories, ads or presentations.
What you can make with Seedance 1.5 Pro
Spokesperson clips
Turn a portrait into a presenter who delivers your message on camera, then render the same line in several languages for each market.
Dialogue scenes
Two characters trading short lines is where lip-sync matters most. Keep each line brief and name who speaks first.
Localized ads
Keep the same visuals and swap the spoken line between languages to test the same ad in different regions without a reshoot.

What is Seedance 1.5 Pro?
Seedance 1.5 Pro is a video model on NovaMotions AI that generates audio and video together with lip-sync. It makes 4 to 12 second clips in 480p, 720p or 1080p from text or from a first and last frame.
Which languages can characters speak?
Write the line in the language you want and the character speaks it in that language with matching mouth movement. Widely spoken languages give the most natural delivery, and short, clear lines sync best.
How should I write dialogue for lip-sync?
Put each spoken line in double quotes, say who speaks and keep lines short enough to fit the clip. Around ten words is comfortable for 5 seconds. Describe the tone too, like whispering or laughing.
Can I use my own character?
Yes. In Image mode, upload a clear, front-facing portrait as the first frame. Seedance 1.5 Pro animates that face and voices your line. A well lit, sharp image gives the best mouth detail.
Which lengths and resolutions are available?
Clips are 4, 5, 8, 10 or 12 seconds long, in 480p, 720p or 1080p, and in 16:9, 9:16, 1:1, 4:3, 3:4 or 21:9.
Can I upload reference clips or audio?
Seedance 1.5 Pro works from text and frames only. For reference images, clips and audio, use Seedance 2.0 Pro, which also voices lines in quotes.
Should I pick Seedance 1.5 Pro or Veo 3?
Both lip-sync. Seedance 1.5 Pro offers longer clips, up to 12 seconds, and every aspect ratio. Veo 3 tops out at 8 seconds but adds 4K and up to 3 reference images.
How many credits does a Seedance 1.5 Pro clip use?
It depends on the clip. Longer clips, higher resolutions and native audio use more credits. The exact amount shows on the Generate button before you spend anything, and the same balance works for video, images and music.
What happens if a Seedance 1.5 Pro generation fails?
Every credit goes straight back to your balance automatically. There is nothing to claim or report. Adjust the prompt or the settings and try again.
Can I use Seedance 1.5 Pro videos commercially?
Yes. Every plan includes commercial use and downloads have no watermark. You are still responsible for what you make, so avoid real people, logos or characters you do not have the rights to.
