Why 30 Seconds Changes Everything
Five seconds can show a moment. Thirty seconds can establish a scene, develop an action, and land a final beat. That extra time makes room for product benefits, narrative turns, and more deliberate camera pacing.
Generate a 30-Second Video
The 30-second preset creates one native Seedance 2.5 video with synchronized audio. No clip assembly or separate narration workflow is required.
- One native 30-second generation
- Native synchronized audio
- Your choice of 480p or 720p
- Text-to-video or image-led opening frame
Selected output: Seedance 2.5 · 16:9 · 720p · 30s. These settings apply to your next generation, not the reference clip.
15s: Seedance 2.0 Mini or Standard · 30s: Pro and above · 60s: Studio and above. Agency adds optional 1080p in the studio.
Allows wider motion interpretation while keeping visual continuity.
Review the exact credit cost and your remaining balance in the studio before starting generation.
Native video audio included automatically
The free trial is one 5-second Seedance 2.0 Mini video at 480p without a reference image, subject to availability. Other selections require a paid account.
30-Second Use Cases
Create product explainers, paid-social stories, launch teasers, character moments, app walkthroughs, and short narrative ads with enough time for a beginning, development, and payoff.
30s vs 5s — What You Can Build
A 5-second clip is ideal for a hook or a single visual beat. A 30-second sequence supports multiple shots, a clearer message, and a complete creative arc while retaining short-form pacing.
