The text file is read line by line, and a corresponding Text3d object is created, which will in turn become a child of an Empty object.
Key frames are created to move the location of the Empty object to scroll.
The scroll speed can be adjusted by changing the end frame value (nEndFrame).
Here is the sample video I made using this script.
To use this the code, you need the following three files:
closingCredits.py
textFile.py
closingCredits.txt
Put closingCredits.py and textFile.py in Blender's scripts directory.
Edit closingCredits.txt using a text editor, and and put it in /tmp.
