Free credits are for a quick preview, not the final video. Use a short duration and lower resolution to check the subject, motion, and prompt. A fuller, more compelling final shot often needs a longer duration and higher supported resolution—use paid credits when your scene needs those settings.

Seedance 2.0 — free AI video generator up to 4K with sound
Generate videos at up to 4K with synchronized sound using Seedance 2.0 on 智擎云. Combine text prompts, reference images, and reference video clips in one generation.
On 智擎云, Seedance 2.0 supports output up to 4K, seven aspect ratios, up to nine reference images with three reference videos in reference mode, and optional generated audio. The maximum credit reservation is shown before submission; successful jobs can settle lower from provider-reported usage, and confirmed failed jobs return the reservation. Paid-access commercial use remains subject to the Terms of Service.
- 4-15 seconds, 24 fps, output up to 4K
- Text, image, and video inputs in one generation
- Up to 4K resolution with native synchronized sound
What sets Seedance 2.0 apart
Seedance 2.0 is designed for high-fidelity generation from text, images, and reference clips, with native audio in a single pass.
Image-to-video with up to nine reference photos
In Reference to Video, combine up to nine images and three reference clips in one request. They can guide identity, product, palette, and motion, but the generated take may still change composition and fine details.
AI-generated audio returned with the video
When enabled, generated foley, room tone, dialogue, and score arrive with the video. Review timing and content before publishing, or disable audio when the clip needs a separate sound-design pass.
How to get the most from Seedance 2.0
On 智擎云, Seedance 2.0 accepts a prompt plus either opening-frame guidance or a reference set of images and clips. These input modes are separate: Reference to Video can combine up to nine images and three clips, while Image to Video uses a required opening frame with an optional closing frame. All references guide a newly generated result rather than locking identity, motion, or composition.
Prompts and references can guide identity, camera language, lighting, and motion, but each run remains independent and details can drift. When audio is enabled, the provider generates it with the video; review timing, dialogue, and content rather than assuming frame-level alignment. On 智擎云 each generation is 4 to 15 seconds at 24 fps.
True multimodal fusion, not post-processing
智擎云 currently accepts text, image, and video inputs: a prompt, up to nine reference images, and up to three reference clips can guide one generation. When sound is enabled, it is generated with the picture rather than supplied as an input.
Three Seedance tiers, three practical trade-offs
Choose Seedance 2.0 for the flagship tier and output up to 4K, Fast for the provider-positioned balance of generation speed and cost at up to 720p, or Mini for cost-efficient 480p and 720p iteration. 智擎云 shows the maximum credit reservation before submission; successful jobs can settle lower from provider-reported usage.
Optional audio generated with the video
When audio is enabled, Seedance 2.0 can generate foley, ambience, impacts, dialogue, and score with the picture. Treat the audio as generated output: review timing, content, and copyright restrictions, or switch it off when separate sound design is required.

Why creators use 智擎云 for AI video generation
The model is ByteDance's. What 智擎云 adds is what makes it usable at work: honest limits, honest billing, and output you are allowed to ship.
Text, images, and video in a single pass
Text, up to 9 reference images, 3 reference videos, and 3 audio references can guide one Seedance 2.0 generation instead of being stitched together afterwards.
Sound generated with the picture
When audio is enabled, Seedance 2.0 can generate footsteps, room tone, impacts, dialogue, and score with the video. Review timing and content before publishing, or switch audio off when the clip needs separate sound design.
Flexible ratios, up to 4K
One prompt covers a 9:16 vertical cut for Reels, a 16:9 master for YouTube, and a 21:9 anamorphic frame for a title sequence. Resolution runs from 480p to 4K, so the same take holds up on a cinema screen and on a phone.
Credits you can predict
The maximum credit reservation is calculated from the selected model, duration, resolution, ratio, and video-reference input, then shown before submission. A successful video job can settle lower from provider-reported usage; confirmed failed jobs return the reservation.
Built for efficient iteration
Use Mini for cost-efficient prompt exploration, Fast when you want a balance of generation speed and cost, and Seedance 2.0 when its longer duration or richer reference inputs fit the shot. Switching models starts a new generation, so results may vary.

Generate with Seedance 2.0 in three steps
No timeline, no keyframes, no editing software. Describe your shot in plain language and generate a finished video clip online.
- 1
Write the shot, attach your references
Describe subject, action, and camera in a focused prompt, then choose either frame guidance or a reference set. Product stills, faces, and clips can guide the result, but they do not lock identity, motion, or composition.
- 2
Set ratio, length and resolution
Pick from seven aspect ratios, a 4-to-15-second duration, and 480p through 4K. The maximum credit reservation updates with your settings before submission; a successful job can settle lower from provider-reported usage. Generated audio is on by default and can be switched off.
- 3
Generate, review, download
Press generate and the job runs in the background - the result waits in My Creations. Output generated with a paid subscription or purchased credit pack may be used commercially under the Terms of Service. If the provider fails the job, your credits come back.
Where Seedance 2.0 generation wins
Marketing teams, content creators, and studios are replacing crew-and-location shoots with a text prompt and an afternoon of iteration.
AI video ads - generate product creatives at test velocity
Growth teams can generate variants of one product spot with different hooks, aspect ratios, and pacing. Attaching the product photo helps guide packaging and product appearance, but logos, labels, and fine details can still change, so review every variant before an ad test.
Social media video with native sound - ready to post
Generate a 9:16 vertical video with optional ambience and impacts in the same task. Review audio timing, dialogue, and content before publishing to TikTok, Instagram Reels, or YouTube Shorts.
4K pitch films and pre-visualization for agencies
Directors and creative agencies can use 4K AI-generated takes to explore an idea before committing production budget. Reference images and clips guide visual style and camera motion, but every result remains a separate generation that should be reviewed for drift.
Seedance 2.0 AI video — frequently asked questions
What is Seedance 2.0 and how does it generate video?
Seedance 2.0 is ByteDance's second-generation video foundation model. On 智擎云 it accepts text, up to nine reference images, and up to three reference video clips, then generates 4-to-15-second clips at up to 4K with synchronized sound. 智擎云 supports all seven aspect-ratio options.
How much does it cost to generate a Seedance 2.0 video?
The maximum credit reservation depends on model, duration, resolution, aspect ratio, and video-reference input, and is displayed before submission. After a successful job, provider-reported usage can lower the final charge and unused credits are returned. Confirmed failed jobs return the reservation.
What inputs can I use with Seedance 2.0 - text, images, or video?
智擎云 accepts a text prompt in English or Chinese, up to nine reference images, and up to three reference video clips in one request. Text works by itself; images and video add visual, subject, motion, or camera guidance.
Which resolutions and aspect ratios are supported?
Resolutions are 480p, 720p, 1080p and 4K. Aspect ratios are 16:9, 9:16, 21:9, 1:1, 4:3, 3:4 and adaptive, which lets the model match the shape of your reference material. Seedance 2.0 Fast and Seedance 2.0 Mini are capped at 720p - that ceiling is the provider’s, and the generator enforces it rather than letting a job fail upstream.
Are Seedance 2.0 AI-generated videos cleared for commercial use?
To the extent permitted by applicable law, 智擎云 does not claim ownership of videos you generate. Videos generated with a paid subscription or purchased credit pack may be used commercially under the Terms of Service. Videos generated solely with free sign-up or promotional credits are for evaluation and personal use only.
Seedance 2.0 vs Sora, Kling, and Runway - what's the difference?
On 智擎云, Seedance 2.0 combines text, image, and video guidance in one generation, produces synchronized sound instead of a silent file, and supports output up to 4K across seven aspect-ratio options.
How do I write good prompts for Seedance 2.0?
Be specific about subject, action, camera, light, and mood instead of relying on vague qualifiers. A concrete prompt gives you clearer variables to review, but no wording guarantees a particular result. If a generation drifts from your intent, reduce it to one action and add detail back one element at a time.
What is the maximum video length, and how do I make longer videos?
Seedance 2.0 generates clips of 4 to 15 seconds per request. For longer sequences, Video Extend creates a separate reference-guided continuation and Video Transition generates a new clip between two endpoint images. Both workflows can drift and require review before assembly.
