面向 creators and developers 的 Seedance 2.0
Seedance 2.0 — ByteDance's motion-first video model, in your browser.
Seedance 2.0 is ByteDance's frontier video model, built motion-first. Where Sora 2 prioritizes single-shot cinematic continuity and Veo 3.1 prioritizes audio sync, Seedance prioritizes the fast cuts, motion graphics, and stylized transitions that dominate TikTok, Reels, and Shorts. Native 2K output, multi-modal inputs (image + text + audio in one prompt), pay-per-credit on hilens — no subscription, credits never expire.
What makes Seedance 2.0 different from Sora 2, Veo, and Kling
Most frontier video models compete on cinematic single-shot quality — a 10-second sustained close-up, naturalistic motion, photoreal lighting. Seedance 2.0 doesn't fight that battle. It's trained for the motion-graphic and fast-cut visual vocabulary that defines short-form vertical content: squish-stretch effects, glitch transitions, duplicate-cloning, color-rain overlays, atomic dissolves, motion-blur sweeps.
The architecture is a dual-branch diffusion transformer with native 2K output and joint video+audio support. Multi-modal input is unusual — you can combine up to four input types (image, video, audio, text) in a single prompt to drive specific motion behavior. For creators iterating on a TikTok aesthetic, this matters: prompt with motion timing directives like "subject duplicates and rotates around a central axis, neon trails follow each copy, glitch frame every 0.5 seconds" and Seedance respects the timing where other models flatten it.
ByteDance also gives Seedance 2.0 a clear advantage on cost-per-quality at the lower tier. BytePlus ModelArk's lite tier is $0.01/second. On hilens, Seedance sits in the prosumer bracket alongside Kling — high iteration count is the expected workflow.
Picking Seedance for short-form vertical: TikTok, Reels, Shorts
Seedance 2.0 is the right model for content built for vertical viewing with action front-loaded in the first 1.5 seconds. Specify "9:16 vertical composition" in the prompt explicitly — Seedance respects aspect cues and frames action accordingly. Leave the bottom third of the frame quiet for captions if you're producing TikTok or Reels content where captions are layered in post.
A typical short-form cycle: 8–12 Seedance generations to land the right motion rhythm. Because credits don't expire on hilens and there's no monthly subscription, iterating heavily one week and not generating the next week doesn't cost extra. For a creator producing 4 TikToks per week leaning on Seedance for motion-graphic style, ~40 generations per week scales reasonably with credit balance compounding across months.
Three platform-specific deep-dives: • /seedance-tiktok — the For You Page motion language Seedance handles well • /seedance-instagram-reels — Reels-native composition and the brand-promo niche • /seedance-youtube-shorts — Shorts-optimized framing and longer-form (8s–12s) motion arcs
Seedance on hilens — Studio
In Studio, pick Seedance 2.0 from the video model picker. Duration up to 12 seconds, native 2K, multi-input prompts (image + video reference + audio + text combined). The credit cost shows on the Generate button before you click. Failed generations are auto-refunded.
Everything runs out of one credit balance. A $5 pack covers Seedance generations alongside Kling, Veo, Sora 2, and every other model on hilens — pick the right model per clip without juggling separate subscriptions. Credits never expire, so iterating heavily one week and skipping the next doesn't cost extra.
常见问题
常见问题
- How does Seedance 2.0 compare to Sora 2 and Veo 3.1?
- Sora 2 wins on single-shot cinematic continuity and held close-ups; Veo 3.1 wins on native audio + photoreal naturalism. Seedance 2.0 wins on motion-graphic vertical content — fast cuts, stylized transitions, duplicate effects, the visual language of TikTok/Reels/Shorts. Choose by clip intent: cinematic vs realistic vs motion-graphic. On hilens, many creators iterate the same prompt across Seedance, Kling 3.0, and Veo 3.1 and pick the winner.
- Does Seedance 2.0 generate audio?
- Seedance 2.0 supports joint video+audio generation. For short-form vertical use cases (TikTok, Reels, Shorts), audio is almost always layered in post regardless — trending audio tracks are added in CapCut or the platform's native editor. For brand or narrative work where in-clip audio matters, Veo 3.1 or HappyHorse are also worth considering on hilens.
- What aspect ratio and duration does Seedance support?
- Seedance 2.0 handles 9:16 vertical (TikTok/Reels/Shorts native), 16:9 widescreen, 1:1 square, and adaptive framing. Duration up to 12 seconds. For vertical short-form, explicitly specify "9:16 vertical composition" in the prompt — the model frames action for the format.
- How much does Seedance 2.0 cost on hilens?
- Each generation costs credits based on duration and resolution. The exact credit cost is shown on the Generate button before you click. Failed generations auto-refund.
- Do I need a subscription to use Seedance 2.0 on hilens?
- No. hilens is pay-per-credit — buy a pack, and credits draw down only on successful generations. There's no monthly fee, no quota reset, and credits never expire. The same balance covers Seedance plus every other model in Studio, so you can switch between Seedance, Kling, Veo, and Sora 2 per clip without separate plans.
