Hi there,

Using Acrobat 8 Professional, I'm trying to insert a .MOV file into my PDF (so it's compatible on PCs & MACs) and it worked great at first but then my students tried it for their projects and they're getting some weird results. The movie either doesn't work OR the sound plays but the movie doesn't, any ideas why?

We converted our movies to .WMV (we're on PCs but they all have Quicktime installed) and everything works great now. Why doesn't the .MOV work all of a sudden?

Thanks,
Chrissy

The embedded multimedia in Acrobat 8 relies on the viewers system having the right player (and video codecs) to play back the embedded video. If the students try playing the MOV in Quicktime on the Mac (without embedding in Acrobat) does it play back properly? I would assume you would have the same result as you do when it is embedded. It sounds like Quicktime (or other player registered on viewers system for playing WMV) has the right codecs to play the WMV but not the MOV, video codecs are far from simple and straight forward.

This is the main reason that Adobe moved to embedding Flash into Acrobat 9, there is no longer any requirement on the user/viewers side except for Reader 9 (or later). The Flash runtime is part of Acrobat/Reader and any Richmedia (multimedia) content created in Acrobat 9 using the Flash/Video tools will play back on any Windows or Mac in Reader 9. I am not trying to talk you into an upgrade, just letting you know that your situation is a large reason for the new method of embedding video (Note: the method available in Acrobat 8 is still available/accessible in Acrobat 9).
