Seedance 2 Audio Copyright Error: What It Is and How to Fix It

If you've been running Seedance 2 or Seedance 2 Fast on Segmind and hitting this error, you're not alone:

The request failed because the output audio may contain sensitive information.
This error occurs because the audio contained in your output video was blocked after matching our audio copyright rules.

What's happening

Seedance 2 generates video with synced audio by default. When the model produces audio that matches known copyrighted material - background music, recognizable soundbites - the request gets blocked at the output stage. The video itself may be perfectly fine; it's the audio layer that triggers the rule.

The fix

Two steps:

1. Mute the audio in your prompt. Deselect audio generation and/or Add something like no background music, silent, no sound to your prompt. This signals to the model to generate a video without a soundtrack, sidestepping the copyright check entirely.
2. Dub separately. Once you have a clean silent video, add your own audio in post - voiceover, music you own, or royalty-free tracks. This gives you full control anyway.

Why this approach is actually better

Auto-generated audio from video models is hit-or-miss. Dubbing separately lets you match pacing precisely, use proper voice talent, and avoid any licensing surprises. The copyright block is annoying in the moment, but the two-step workflow produces a better result every time.

If you're building on the Seedance 2 API via Segmind, update your default payload now and save yourself the retry loop.
