What is Denoising Strength?
A parameter controlling how much of the source image or video is preserved during generation. Lower values preserve more of the original, higher values allow more creative change.
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.
