Is it possible to lock a Quicktime file, to prevent someone from altering it, copying it, importing it etc? However they can still view the file?
I've embedded Quicktimes online which did not allow me to grab the file even though I have QT Pro. Is that a files side or server side thing?
Is something like that possible besides resorting to OSX's file settings for Read/Write permissions?

Hmm I've seen these embeded quicktimes that doesn't allow "save as source..." option.
I think is either something on the embed code, or has something to do with streaming... i'm not sure anyways...
Try finding some of those and take a look at the embed code...

I remember seeing them at pixar:

Hmm, found sumfink...
"There are a couple of ways in which a movie can be protected from copying. First, if the movie is embeded in a web page, the author can set KIOSKMODE=True in the EMBED tag. If QuickTime plug-in sees this setting, it will disable the save options, even if QuickTime Pro is installed. However, in such cases one can view the source of the web page (as described above) and use the browser's "Save as..." function to save the movie.
However, some movies are saved in such a way that even if you manage to save the movie to you hard drive, if you then make any changes to the movie, QuickTime Player will not allow you to save the edited movie. An error message will appear that reads: "This movie does not allow saving."
Video editing programs like Cleaner allow authors to save movies in such a way that further changes to the movie are disallowed. When the author saves the movie, he simply enables the "disallow saving" check box. Some filmmakers chose to do this to prevent others from altering their work. Others chose this option to discourage users from making local copies of movies viewed online. "

One you watched the movie with your browser, it's in the cache, whether or not you made it downloadable. In other words, the movie is already downloaded to your harddrive.
