####################### Script for file 001.MOV
####################### Goals: 4
####################### This script is PHP generated for processing sport videos. It overlays a
####################### score bar (updated depending on number of goals and team names) and a
####################### splash screen with information about the game.
####################### Splitting requires that the key frame be calculated for each partial temp
####################### file so getKeyFrame must be called within the script and not precalculated.
