Denoise – Immediately denoises all denoisable elements using the most advanced denoising mode that is available for the image.
Denoise Amount – Mixing coefficient between the original (noisy) and processed (non-noisy) image. It allows fine-tuning the effect strength to find the sweet spot between preserving the finest details and removing excessive noise.
Custom Denoise
All – Selects all items for denoising.
None – Unselects all previously selected items for denoising.
Inverse – Inverts the current selection.

Elements that cannot be denoised are not listed.
Denoise Mode – There are 4 denoising options available. The Denoise amount option can be used later to interactively control the strength of their effect.
Fireflies Only – Fast filter that just removes very bright pixels from the image (created by any source - noise, caustics, sun reflections, etc.) NVIDIA GPU AI – Very fast GPU-based denoiser. Available only on NVIDIA GPUs when the optional NVIDIA AI Denoiser Corona component has been installed. Intel CPU/GPU AI – (also known as Intel Open Image Denoiser) Fast denoising filter applied when render ends. It is a CPU-based denoiser, running on both Intel and AMD CPUs. It does not have any additional requirements to be executed; if the CPU runs Corona, it can run this denoiser. It is slower than NVIDIA GPU AI denoiser, but can achieve better quality.

In Corona 11, the Intel AI denoiser is supported only by Windows-based systems and its GPU mode only works on NVIDIA GPUs.
High Quantity – A more memory and CPU-intensive filter that removes all random noise from the image, creating a noise-free image considerably faster than waiting for the rendering to converge.

NVIDIA GPU AI mode is not suitable for denoising animation.
Denoise Radius – Controls the radius of the denoising blurring.
