Question 1

What is Seedance 2.0?

Accepted Answer

Seedance 2.0 is ByteDance's second-generation AI video model, a major upgrade from Seedance 1.5. It produces significantly better motion quality, supports native audio generation for free, offers first+last frame control for precise video narratives, and includes multi-language lip-sync capabilities. Kensa is one of the first platforms in the world to offer access.

Question 2

Is audio generation really free with Seedance 2.0?

Accepted Answer

Yes! Unlike other models that charge extra for audio, Seedance 2.0 includes native audio generation at no additional cost. Simply enable the 'Generate Audio' toggle and your videos will include synchronized sound effects, ambient audio, and even lip-sync dialogue matching the visual content.

Question 3

How does First + Last Frame mode work?

Accepted Answer

Upload two images — one for the opening frame and one for the closing frame. Seedance 2.0 generates a smooth, natural video transition between them. This is perfect for product reveals, seasonal transformations, before/after comparisons, and any scenario where you need precise control over how a video starts and ends.

Question 4

What quality and duration options are available?

Accepted Answer

Seedance 2.0 supports durations from 4 to 15 seconds and two quality tiers: 480p (7 credits/s) and 720p (15.4 credits/s). Easter promo: the starter config (4s, 480p) is half price at 14 credits instead of 28. All other durations and resolutions are at standard pricing.

Question 5

How does Seedance 2.0 compare to Seedance 1.5 Pro?

Accepted Answer

Seedance 2.0 is a generational upgrade: dramatically better motion quality, free native audio (1.5 charged extra), multi-language lip-sync, longer videos (up to 15s vs 12s), and support for video/audio references. At 7+ credits/s it's priced as a premium model. Easter promo lets you try the starter config (4s 480p) at just 14 credits. Seedance 1.5 Pro still offers 1080p output at lower per-second pricing for budget-conscious work.

Question 6

Can I use reference videos and audio with Seedance 2.0?

Accepted Answer

Yes! Seedance 2.0 supports rich reference inputs: up to 9 reference images, 3 reference videos, and 3 audio tracks. These references guide the generation style, motion, and audio of your output video. This is ideal for maintaining visual consistency across series or matching a specific aesthetic.
