Seedance 1.5 Pro is an earlier ByteDance video model with sound. It makes clips of 4 to 12 seconds from a text prompt or a start image, at any of five aspect ratios, and lists 720p output. Sound doubles the price. A 5-second clip costs 239 credits with sound off, and 478 with sound on.

#What it costs
These are credits per clip, as of 2026-10-10. The Studio shows the live quote for your settings before you generate, and the total it charges is that quote multiplied by Count.
| Length | Sound off | Sound on |
|---|---|---|
| 4 s | 192 | 383 |
| 5 s | 239 | 478 |
| 8 s | 383 | 765 |
| 10 s | 478 | 956 |
| 12 s | 574 | 1,148 |
The Studio starts with sound on, so the first quote you see is the sound-on price. Switch sound off to pay the lower price.
The table shows selected lengths. Every whole second from 4 to 12 is available and priced in the same way, and the Studio shows the exact quote.
#Use it in Studio
Step 1: Open Create Video
In Studio, open Create Video. Sign in when the Studio asks, because every generation needs an account.
Step 2: Choose Seedance 1.5 Pro
Open the model picker, which groups models by maker, and choose Seedance 1.5 Pro.
Step 3: Write your prompt
Describe the clip. To start from a picture, attach one start image (JPEG, PNG or WEBP, up to 20 MB).
Step 4: Set the output
Set aspect ratio, length, sound and Count from 1 to 4.
Step 5: Check the price and generate
The Studio shows the credit price for your settings. Videos run in the background: the card updates in place when the clip is ready, and the clip is saved to your Library.
#Limits
- You need to be signed in to generate. Seedance 1.5 Pro is available on every plan, including Free; credits are the limit.
- One start image only. The Studio has no end frame, no multiple reference images and no video-to-video input.
- A video that has not finished within 30 minutes is marked failed and refunded. A failed generation is refunded, and the Studio does not run a different model in its place.
