# About Grain Removal

Use the Degrain tool in Lustre to remove film grain, video noise, and other compression noise from your shots while minimizing damage to the image. Grain removal can be done at any time during the project workflow, but it is typical to perform an initial degrain operation on the source image before primary colour grading begins.

A recommended grain removal workflow consists of the following basic steps. You can view the result as you work. See Viewing the Result.

1. Define the degrain cache location. | Project Settings and Rendering Settings.
2. Analyse the grain profile of the input image. | Analysing the Frame.
3. Perform post-analysis cleanup. | Post-Analysis Clean-Up.
4. Cache the filtered images. | Caching the Result.
5. Apply input and secondary grading. | Primary Colour Grading and Secondary Colour Grading.
6. (Optional) Analyse the grain profile of secondaries to degrain isolated parts of the image. | Removing Grain with Secondaries.
