I have made quick time movies on my Mac. How can I make them

Customer Question

I have made quick time movies on my Mac. How can I make them secure so when I teach to students over the intenet (webcam or online course etc) they don't use a "caputure file' or something else to take my material and put it up on live wire?

You can mitigate (a bit) this risk by embedding a ref movie and having it call your actual media.

You can also take it further by using LiveStage Pro to set the 'Save as uneditable' flag or use Plug-In Helper.

This makes cutting, pasting export etc. impossible in QT Pro even if the user gets the movie file.

Obviously this, like all sorts of copy protection, is circumventable but these measures raise the bar for the would be 'saver'.

You can get even more creative with LiveStage Pro (and possibly other wired QuickTime authoring tools) using QuickTime wired actions to check for certain conditions before allowing playback.
