Example: Denoising Presets
The example below illustrates how VRayDenoiser works using the presets. A purposely noisy render was set up using the Progressive Image Sampler Type with Render Time set to only 3 minutes to leave plenty of noise in the render.

Denoising Animations
When denoising animations, it is recommended to use the Standalone Denoiser Tool. Unlike the denoiser integrated in the UI, the standalone tool can do frame blending for animations, which reduces flickering. The integrated denoiser only works on the rendered frame and does not take the next and previous frame(s) into account, like the standalone tool does.
To denoise an image sequence with vdenoise run the following command:
Code Block |
---|
vdenoise -inputFile="path\to\sequence_????.ext |
where the question mark (?) replaces the digits in the sequence's file names.
For example, if the images in the sequence are named anim_0001.exr, anim_0002.exr, etc. and are located in the folder c:\renderoutput, the full command will be:
Code Block |
---|
vdenoise -inputFile="c:\renderoutput\anim_????.exr |
When that command is run, the sequence is read and for each frame, the specified number of adjacent frames are also considered. A new output image is then written for each frame.

The NVIDIA AI denoiser does not perform frame blending and will likely produce flickering when denoising animations. |
