After the frame is analysed, you can view the result of applying the degrain filter on all or a portion (sub-region) of the image. For increased performance, it is recommended that you select the sub-region where you want to view the filtered result.

To apply the degrain filter:

1. Navigate to the frame you want to view.
2. Do one of the following:
   • If you want to degrain the entire image, click Degrain in the Image menu.
   • If you want to degrain a region of interest, click Degrain in the Colour menu.
3. (Optional) Enable the Sub-Region Filtering button and drag to define an area to view with the result. See Working with Sub-Region Boxes.
   NoteUnlike sub-region analysis boxes, the sub-region filtering box cannot be deleted, only disabled.
4. Enable the Apply Degrain button to view the filter on the image.
