What is Denoising Strength?

How it works

Denoising strength determines the balance between preserving source material and generating new content. In image-to-video and video-to-video workflows, a low denoising strength (0.2-0.4) keeps most of the original content intact with subtle modifications. A high denoising strength (0.7-1.0) gives the model more freedom to change the content dramatically. For production workflows, this parameter is critical for controlling the degree of transformation. When you want to animate a product photo with subtle motion, use low denoising. When you want to create a completely new visual from a rough sketch, use high denoising. Most professional tools expose this parameter through their API, even if the web interface simplifies it.
