We should do another tutorial for some time now, I know. Meanwhile you can try, if you find your way trought this: https://dl.dropboxusercontent.com/u/13685023/Schwing_Bauchbinde.zip
. Its a template, that I did for a sports event last summer.
The name of the video file "06_ISV_Bauchbinde_alpha" is hardcoded in the script and the file is missing from the download, because it is 5 MB. It is a Quicktime encoded with the animation codec with alpha channel. There are four variables f0, f1, channel and preview. The first two set the textfields. The other two add a little flexibility. The client controlling the event had a "Preview" button, that let it run on another channel, so with "channel" you tell the video, on what channel to tun and "preview" is for stoping the template differently for the preview (no out animation).
