there are several programs available..
the most common one may be windows movie maker..

the basic actions that most programs help you perform are:
cutting into clips...and editing the clips
(esp. trimming frames from the "front" and "back" of the clips)
adding transitions between the clips...fade in/out, or other
images that blend from one image to another...

and the title and credits can be added

there are many other programs...

final cut pro, pinnacle, adobe premier, apple I-Movie,
video editing and authoring utilities..
they range from 30 - 100 dollars..
