Question 1

What is Seedance 2.0 (also searched as Seed Dance 2.0)?

Accepted Answer

Seedance 2.0 (also known as SeedDance 2.0, Seed Dance 2.0, or Seedance2.0) is ByteDance's latest AI video generation model, released in February 2026. Unlike traditional text-to-video tools, it accepts four types of input simultaneously — text, images (up to 9), videos (up to 3, totaling 15 seconds), and audio files (up to 3, totaling 15 seconds). You can upload up to 12 reference files per generation. It outputs 1080p to 2K resolution videos between 4–15 seconds long, with native audio synchronization and lip-sync support in 8+ languages. Note: You may see Seedance 2.0 spelled as Sedance 2.0, Sidence 2.0, Sidense 2.0, Seedence 2.0, See Dance 2.0, or Sea Dance 2.0 — they all refer to the same ByteDance AI video model.

Question 2

Who made Seedance 2.0?

Accepted Answer

Seedance 2.0 is developed by ByteDance, the parent company of TikTok. It's built on the Seedream 5.0 architecture and is part of ByteDance's broader "Seed" ecosystem of foundation models spanning language, image, and video generation.

Question 3

Is Seedance 2.0 the same as Dreamina?

Accepted Answer

No. Dreamina (also called Jimeng) is ByteDance's creative platform where you access the tool. Seedance 2.0 is the underlying AI model that powers the video generation feature within Dreamina. Think of Dreamina as the app and Seedance 2.0 as the engine.

Question 4

What's new in Seedance 2.0 compared to Seedance 1.0?

Accepted Answer

Major upgrades include: true multimodal input (4 input types vs. text/image only), native audio generation with lip-sync, dramatically improved character consistency across shots, automatic multi-camera angle switching, 2K resolution output, and a reported 90%+ usability rate compared to the ~20% industry average.

Question 5

What is the @ reference system in Seedance 2.0?

Accepted Answer

It's Seedance 2.0's unique feature that lets you assign specific roles to each uploaded file using @mentions. For example: "@Image1 for character appearance, @Video1 for camera motion, @Audio1 for rhythm." This gives creators director-level control over exactly how each reference influences the output.

Question 6

How do I access Seedance 2.0?

Accepted Answer

Three primary options: 1) Dreamina website (jimeng.jianying.com) — Requires paid membership starting at 69 RMB/month (~$9.60 USD). 2) Little Skylark (Xiao Yunque) app — Currently offers free trial with 3 free generations + 120 daily points. 3) Third-party platforms — Services like Seedance 2.0 Online, Dzine, and PhotoGrid provide access through ByteDance's API.

Question 7

How do I get better results with Seedance 2.0?

Accepted Answer

Community-tested best practices: Start with 5-second test clips (~30–35 credits) before committing to full 15-second generations. Use high-quality reference images with good lighting. Write clear prompts specifying action, camera movement, and mood. Generate during off-peak hours for faster speed and better consistency. Always reuse the same @character reference across clips to prevent face drift. Switch to "All-Round Reference" mode (not the default "Start/End Frame") for full multimodal control.

Question 8

What input formats does Seedance 2.0 support?

Accepted Answer

Images: Up to 9 per generation (used for character appearance, background style, lighting references). Videos: Up to 3 clips, 15 seconds total (used for camera movements, action pacing, choreography). Audio: Up to 3 MP3 files, 15 seconds total (used for lip-sync, beat sync, rhythm-driven editing). Text: Descriptive prompts in natural language. Maximum 12 reference files across all types per generation.

Question 9

What aspect ratios does Seedance 2.0 support?

Accepted Answer

Seedance 2.0 supports 16:9, 4:3, 1:1, 3:4, and 9:16 — covering YouTube, Instagram, TikTok, and all major social media formats.

Question 10

Is Seedance 2.0 free?

Accepted Answer

Partially. The Little Skylark app currently offers free access with daily point allowances — enough to generate about 15 seconds of video per day. On Dreamina, full features require a paid membership starting at 69 RMB/month (~$9.60 USD). Some third-party platforms also offer free credits for new users.

Question 11

How much does Seedance 2.0 cost?

Accepted Answer

Free tier (Little Skylark app): 3 free generations + 120 daily points (enough for ~15s/day), currently in a "zero point deduction" promotional period. Dreamina Standard Membership: 69 RMB/month (~$9.60 USD) — unlocks Fast Mode, commercial licensing, advanced multi-modal inputs. Third-party access: Varies by platform.

Question 12

How much does the Seedance 2.0 API cost?

Accepted Answer

ByteDance hasn't released official API pricing yet. Third-party estimates suggest approximately $0.30–$0.50 per second of generated video. For reference, Sora 2's official rate is ~$5 for a 10-second 1080p video. Official pricing is expected after the February 24th public launch.

Question 13

Is Seedance 2.0 output watermark-free?

Accepted Answer

On paid plans, yes — videos are completely watermark-free and ready for commercial use. Free-tier or trial plans may include visible watermarks.

Question 14

Can I use Seedance 2.0 videos commercially?

Accepted Answer

With a paid Dreamina membership, you get commercial licensing for generated content. However, always be mindful of potential intellectual property issues when using copyrighted reference materials as inputs.

Question 15

Seedance 2.0 vs Sora 2 — which is better?

Accepted Answer

Seedance 2.0 offers native 2K resolution (vs Sora's 1080p), multimodal input (text + image + video + audio vs text + image only), native beat sync and lip-sync in 8+ languages, and a lower starting price (~$9.60/mo vs $20/mo). Sora 2 offers longer max duration (25s vs 15s), stronger physics realism, and a larger English-speaking community. Choose Seedance 2.0 for reference-heavy template work; choose Sora 2 for long-form narrative and physical accuracy.

Question 16

Seedance 2.0 vs Runway Gen 4 — how do they compare?

Accepted Answer

Runway offers a superior built-in editing suite (masking, compositing, inpainting) and has Hollywood partnerships (e.g., Lionsgate). Seedance 2.0 wins on multi-reference input capability and character consistency. Runway supports up to 4K resolution but at higher cost. If your workflow is generation-focused, Seedance 2.0 has the edge. If you need editing tools built in, Runway is stronger.

Question 17

Seedance 2.0 vs Kling 3.0 — which should I choose?

Accepted Answer

Kling's biggest advantage is duration — it can generate up to 2 minutes per video, compared to Seedance's 15-second cap. Seedance 2.0 excels in multimodal reference input and audio synchronization. Kling offers better value for straightforward, high-volume generation at lower cost. Choose Seedance for reference-driven, template-based work; choose Kling for rapid prototyping and longer clips.

Question 18

What are the best Seedance 2.0 alternatives?

Accepted Answer

Top alternatives include Sora 2 (OpenAI), Runway Gen 4, Kling 3.0 (Kuaishou), Pika 2.5, Veo 3.1 (Google), and platforms like Seedance 2.0 Online that integrate multiple models in one interface. The best choice depends on your specific needs — duration, quality, price, reference capabilities, and workflow integration.

Question 19

Can I use multiple AI video tools together?

Accepted Answer

Absolutely — and many professional teams do. Common combinations include Seedance 2.0 for template-based assets and multi-material creation, Sora 2 for high-end cinematic content, and Kling for rapid prototyping and longer-form clips. A Reddit survey found most experienced creators pay for 2–3 subscriptions, using each tool where it's strongest.

Question 20

What are the limitations of Seedance 2.0?

Accepted Answer

15-second cap per generation (Sora does 25s, Kling does up to 2 minutes). No real human face upload (currently restricted to prevent deepfake abuse). Audio glitches when text is too long for the 15s window. Some complex motions (e.g., opening doors, hand movements) still produce artifacts. Results still vary between generations despite a ~90% usability rate. No built-in video editor — you still need Premiere, DaVinci, or CapCut for post-production.

Question 21

Why does Seedance 2.0 block my face upload?

Accepted Answer

Since February 2026, Seedance 2.0 has temporarily suspended real human face uploads to prevent deepfake misuse. On the Dreamina and Doubao apps, you can still create a "digital avatar" by completing live identity verification. You cannot upload other people's photos as character references. Workaround: Use stylized characters, 3D renders, or apply image-to-image filters to remove photorealistic biometric features before uploading.

Question 22

Why did my generation fail?

Accepted Answer

Common causes: Compliance interception (you uploaded a realistic human face — most common reason), file format issues (unsupported formats or oversized uploads), queue overload (server capacity during peak usage periods). Solution: Use stylized or cartoon-style character images instead of real photos.

Question 23

Why is Seedance 2.0 generation so slow?

Accepted Answer

Seedance 2.0 requires heavy computation for its advanced motion modeling and physics simulation. Free-tier users are placed in "standard speed" queues that can take significantly longer. Upgrading to a paid membership unlocks "Fast Mode." Generating during off-peak hours also helps.

Question 24

How do I extend videos beyond 15 seconds?

Accepted Answer

Seedance 2.0 has a video extension feature where you can upload a generated clip and extend it. However, each extension is a separate generation, and you may notice visible seams at connection points. Key tip: Reuse the same @character reference files across extensions to maintain consistency.

Question 25

Is there a Seedance 2.0 API available?

Accepted Answer

As of February 2026, ByteDance has not released an official public REST API. However, third-party providers including fal.ai, WaveSpeedAI, Kie AI, and APIYI are already offering API access. ByteDance's Volcengine platform has API infrastructure for other Seed models, and official API access is expected soon.

Question 26

Can I integrate Seedance 2.0 into my own app?

Accepted Answer

Yes, through third-party API providers. The generation flow is typically async with polling — you submit a request, receive a job ID, and poll for results. Check providers like WaveSpeedAI, fal.ai, and APIYI for current endpoint documentation.

Question 27

Will Seedance 2.0 be open-source?

Accepted Answer

ByteDance has released open-weight versions of some Seed language models, but whether Seedance 2.0 will receive similar treatment remains an open question. If it does, it would enable fine-tuning, local deployment, and custom integration patterns impossible with API-only access.
