Shot clean-up is the process of eliminating or masking undesired aspects from footage and photographs. There are numerous techniques to this, as well as a large range of software options.
Workflows
Method 1: Clean and restore footage using Photoshop’s cleaning and restoration tools.
Method 2: Create a clean plate in Photoshop and import it as an image into After Effects. Using a rotoscope and camera tracking, insert the clean plate where it is needed.
Tools

Spot Healing – For removing dust, thin wires, creases.
Healing Brush – Like the Spot Healing but requires an image to copy.
Patch Tool – For replacing large sections and nice quick blending.
Content-Aware Move – For covering elements but blending is quick and harsh.
Red Eye – Gets rid of red-eye from old photos
