% Package: textpos is required for textblock*
\usepackage[absolute,overlay]{textpos}


% fullFrameMovie
%
% Arguments:
%
%   [optional]: movie-options, seperated by &
%       Supported options: loop, start=N, end=N, autostart
%   Default: autostart&loop
%
%   1. Movie file
%   2. Poster image
%   3. Any text on the slide, or nothing (e.g. {})
%
% Example:
%   \fullFrameMovie[loop&autostart]{apollo17.avi}{apollo17.jpg}{\copyrightText{Apollo 17, NASA}}

        % to make this work for both horizontally filled and vertically filled images, we create an absolutely
        % positioned textblock* that we force to be the width of the slide.
        % we then place it at (0,0), and then create a box inside of it to ensure that it's always 95% of the vertical
        % height of the frame.  Once we have created an absolutely positioned and sized box, it doesn't matter what
        % goes inside -- it will always be vertically and horizontally centered
