The question is completely formulated in the title.
However, to make it more presize, I am making presentations for lectures. The presentations are done in Mma. I have some illustrative material to show in a form of movies (avi and gif). It is possible to remove Mma from the screen, open a file with the movies and play one. I would like, however, to be able to call a movie from Mma just for the sake of speed. In addition it is aestetically better.
I tried to embed a hyperlink into the presentation notebook to call the movie file. This does not work. It opens an empty notebook with the title of the movie-file in question, and after a rather long waiting the notebook becomes filled by some symbols. Evidently, it opens the file rather than plays it.
So, can I do anything?
ListAnimate
with the list of its frames to include it directly. The notebook size will increase quite quickly with the number of frames though. $\endgroup$Style[Dynamic[Refresh[Import["http://pages.uoregon.edu/noeckel/computernotes/StopMotion.mov", "Animation"], None]], DynamicEvaluationTimeout -> 60]
which is from this answer. $\endgroup$
