Seadance-video.com
Seadance-video.com offers an online workflow for generated video. Its service overview explicitly says it is an independent platform, unaffiliated with ByteDance or Seedance. The model names identify technology the interface says it uses, rather than ownership of the website.
Give the generator a scene and references
The homepage presents text-to-video, image-to-video and video-to-video modes. You can describe the intended action and camera movement or supply a reference that establishes the subject. The publisher also promotes local editing and multimodal references for guiding a scene.
Those controls may help communicate a creative brief, but the site's character-consistency and prompt-adherence claims are not independent output benchmarks. Review the generated movement and compare reference details before treating a clip as finished advertising material. A product scene needs to preserve the actual product, not simply resemble the requested visual style.
Confirm the settings available for your model
The visible generator lists 16:9, 9:16 and square aspect ratios, durations from four to thirty seconds, and 480p or 720p resolution. Other marketing sections advertise native 4K output, while the creation instructions mention different duration and model limits.
Check the active model's actual settings before buying credits for a particular delivery specification. A general 4K headline does not establish that every mode or plan exports at that resolution. Use a short test scene to inspect framing and continuity, then confirm whether the export meets the destination's requirements. The service describes generation history and previews, with sign-in required to access that history.
Budget against a specific generation quote
The pricing page lists Starter at $39.90 per month with 2,000 credits and separate higher-volume plans. Its estimated video counts differ substantially by model and refer to particular five-second settings. Do not add those alternative allowances together or read the largest count as a promise for thirty-second clips.
Review the credit estimate for your chosen duration and model before submitting a batch. Confirm the current license, renewal and reference-upload terms for client projects. The publisher's examples show intended creative uses, not proof that a generated asset will meet a campaign's factual or rights requirements.
