1. A method for combining a source video signal and one or more graphical elements using a preexisting computer-based graphics program to generate a composite video signal, said method comprising:

  • providing a work area in said preexisting computer-based graphics program to enable a user to add data objects thereto, said data objects being available from said preexisting computer-based graphics program and associated with said one or more graphical elements;

    providing in said work area, a region for said source video signal;

    enabling said user to interact with said work area to control the location, size, and appearance of said one or more graphical elements in relation to said region for said source video signal;

    generating a graphical overlay using said graphical elements according to the current state of said work area;

    combining said graphical overlay and said source video signal to generate said composite video signal; and

    providing said composite video signal as an output to be used by a graphics engine;

    wherein said preexisting computer-based graphics program is a commercially available software program that is independently operable to provide stand-alone functionality for at least one use other than said method.
