Go to the first frame of the shot where
you want to find and remove dust.
On the image window, drag a box around
each dust artefact that you find. Make the box as small as possible—to
just surround the dust and leave five to ten pixels of space around
the artefact. This reduces the portion of the image that is affected
by the removal process. See
Working with Boxes.
If needed, tweak the Contrast, Grow,
and Soft Edge parameters. Enable or disable Show Mask as needed.
Any changes you make are applied only to the artefact in the currently
selected box.
Go to the next frame and check for artefacts,
removing them as needed.
Continue the process frame by frame until
the shot is cleared of artefacts.
