Seedance 2.5 is the newest video model from ByteDance, and the studio above runs it in your browser: write a prompt or upload a photo, pick a tier, and get a clip with sound. Both tiers call it through WaveSpeed, a third-party API provider. We are an independent studio, not affiliated with ByteDance.
At a glance
- ByteDance launched the model on July 31, 2026 (Seed blog).
- The model makes up to 30 seconds of video and audio in one pass. This studio caps clips at 15 seconds for now.
- Fast tier: 2.5 Flash at 480p, 2.5 Turbo at 720p and 1080p. Pro tier: the standard endpoint.
- New accounts get 48 free credits, enough for one 4-second 480p Fast clip.
What is Seedance 2.5?
It is the video model ByteDance's Seed team released after Seedance 2.0. Like 2.0, it generates picture and sound together. ByteDance's launch post centers on three upgrades:
- Longer takes. Up to 30 seconds per generation, twice the 15 seconds of Seedance 2.0, plus rounds of extension for longer stories.
- More references. Up to 30 images, 10 video clips and 10 audio clips in one request.
- Finer editing. Timestamp-level edits to picture and sound, plus green screen and camera perspective edits.
At launch, ByteDance rolled the model out in its Jimeng AI and Doubao Pro apps and said API access would follow on BytePlus ModelArk. API providers such as WaveSpeed now serve it, which is how this studio reaches it.
Fast and Pro tiers in this studio
The model comes in several variants. We group them into two tiers, so you pick speed or quality instead of an endpoint:
| Tier | Variant | 480p | 720p | 1080p |
|---|---|---|---|---|
| Fast | Flash (480p), Turbo (720p and 1080p) | 12 credits/s | 20 credits/s | 22 credits/s |
| Pro | Standard model | 18 credits/s | 36 credits/s | 90 credits/s |
Fast is for drafts and social clips. Pro runs the full model for final shots. A 5-second 720p clip costs 100 credits on Fast and 180 on Pro.
What you can set:
- Text to video: a prompt of up to 3,500 characters, six aspect ratios (16:9, 9:16, 1:1, 4:3, 3:4, 21:9) and up to 9 reference images.
- Image to video: a start frame and an optional end frame. The clip keeps your photo's aspect ratio.
- Length: 4, 8, 12 or 15 seconds.
- Audio: native sound is on by default. Switch it off for a silent clip you will score yourself.
Seedance 2.5 vs Seedance 2.0
| Seedance 2.0 | Seedance 2.5 | |

| Editing | Extension and editing | Timestamp-level edits, green screen, camera perspective |

Figures come from ByteDance's 2.0 and 2.5 launch posts. ByteDance also says 2.5 improves textures, skin, lighting and color, to look less artificial than earlier models.
How to make a clip here
- Pick a mode. Text to video starts from words. Image to video uses your photo as the first frame.
- Write the shot. In a few plain sentences, describe the subject, the action, the camera and the sound.
- Choose tier, resolution and length, then generate. The credit cost shows on the button before you click. Our 4-second 480p Fast test rendered in 78 seconds; longer and sharper clips take more time.
Prompt tips for better clips
- Lead with the shot, not adjectives. Say who is on screen, what they do and where, then add the camera move.
- Split multi-shot clips into time ranges. ByteDance's own examples give each range its own action, such as 0–5s, then 6–10s.
- Name the sound. Audio follows the prompt, so mention dialogue, music or ambience if you want it.
- Draft on Fast, finish on Pro. Lock framing at 480p, then rerun the keeper on Pro at 720p or 1080p.
What a clip costs
Credits are billed per second of video, at the rates in the table above. Credit packs start at $9.90 for 400 credits, about four 5-second 720p Fast clips, and pack credits never expire. Subscriptions lower the price per credit and unlock 1080p. Every option is on the pricing page.
