Apple 'mov' files, as supported by pdf.

Indeed. Actually in that document the inclusion concerns a movie, used
as overlay in a flowchartcell, which itself is drawn by metapost
runtime, and converted to pdf by tex. A rather nice chain of actions.

I first made an animated gif out of gifs produced from the mp epses,
using adobe photoshop. The animated gif can be made by convert, althouhj
I used a free MS program which location I've forgotten but which works
ok. Then I asked a friend to convert that gif to a mov using adobe
premiere (maybe some day I will buy that program).

Well, the shortest file I can think of is:

  \starttext \setupoutput[pdftex] \externalfigure[somekind.mov]
\stoptext

You can turn on a preview with: 

  \externalfigure[somekind][preview=yes]  

and activate a loop by [repeat=yes]

(You can test this with the movie as included in the 1999-003.zip)
