I have someone creating videos with camtasia studio. Although they say their copy of the software is legal I would not like to have videos created with pirated software and have the videos I need confiscated.

So my question is, how can I ensure the videos in avi or flv format created with camtasia studio are legal?

Thank you

Its the content of the video not the software that creates it that would be questioned, Is the content legal, speak to an attorney. – Moab Sep 18 '10 at 14:58
The content is legal, the guy will be making the videos himself. e-learning stuff. – Artur Carvalho Sep 18 '10 at 17:45

There is nothing you can do to verify this. Even if there were a watermark in the headers or something (I doubt it) it could easily be removed even simply by re-encoding it with something else farther down the line.
