The profiles included with Mercalli quickly get you started with an initial image stabilisation. Once you have selected a profile and assessed the result, you can configure additional settings to optimise it. The profiles are divided into the following categories:
Versatile : universal image stabilisation
Handheld camera (Handy Cam) : stabilisation of images filmed using a handheld camera
Shoulder-mounted camera (Shoulder Cam) : stabilisation of images filmed using a shoulder-mounted camera
Tripod : optimisation of images filmed using a tripod or simulation of tripod use
Rescue : stabilisation of sequences with a lot of camera shake, generally spontaneously filmed footage
In Practice (Special application) : stabilisation of sequences filmed in specific situations
More than one profile may be suitable for a scene you have filmed.
The effect of a profile depends on many different factors in your original video footage.
If you are not happy with the stabilisation result of one profile, simply try another one that might be suitable. The profile names and descriptions should help you with your selection.
