Frequently Asked Questions

Seedance is an AI video generation model developed by ByteDance (the company behind TikTok). It can create high-quality videos from text prompts or images, supporting up to 2K resolution with audio generation. The latest version, Seedance 2.0, is available through platforms like Jimeng and Dreamina. Learn more in our complete guide.

Yes, you can use Seedance for free. Platforms like Jimeng and Dreamina offer daily free credits for new users. Third-party API providers such as fal.ai and Replicate also provide free trial credits. Check our pricing page for a full breakdown of free and paid options across all platforms.

Seedance itself is not open source — ByteDance has not released the model weights publicly. However, you can access Seedance through open APIs on platforms like fal.ai and Replicate, which provide standard REST endpoints. See our API guide for integration details.

Yes, Seedance 2.0 supports audio generation. It can produce synchronized sound effects and ambient audio that match the video content. This is a significant upgrade from earlier versions (1.0 and 1.5) which were video-only. For details on each version's capabilities, see our version comparison.

Videos generated with Seedance 2.0 can include audio. The model generates synchronized sound effects automatically. Earlier versions (1.0 Lite, Mini, Pro, Fast, and 1.5 Pro) produce silent videos. If you need audio, make sure you're using Seedance 2.0 on a platform that supports it, such as Jimeng.

The easiest way to use Seedance is through Jimeng (即梦) at jimeng.jianying.com. Create an account, select the video generation tool, write a text prompt describing your desired video, and hit generate. For a detailed walkthrough including prompt tips and advanced features, read our complete guide.

Seedance applies content moderation filters, especially on Chinese platforms like Jimeng and Doubao. These filters restrict NSFW content, politically sensitive topics, and certain copyrighted material. The level of filtering varies by platform — third-party API providers like fal.ai and Replicate may have different content policies.

Commercial usage policies depend on the platform you use. Jimeng's paid plans generally allow commercial use of generated videos. For API access through fal.ai or Replicate, check their respective terms of service. Always review the specific platform's licensing terms before using generated content commercially.

Seedance 2.0 supports videos up to 15 seconds in length. Earlier versions had shorter limits — Seedance 1.0 supported up to 10 seconds, and 1.5 Pro up to 10 seconds as well. For longer videos, you can generate multiple clips and stitch them together in a video editor. See our version comparison for full specs.

For Jimeng (the primary platform), a Chinese phone number is required for registration. However, there are workarounds: you can use virtual phone number services, access Seedance through Dreamina (the international version), or use API providers like fal.ai and Replicate which don't require Chinese verification. Our registration guide walks through each method step by step.
