We had a weird problem where this happened with vidoe downloaded to machines when people were logged into accounts on a Mac server.  We found out that by just creating local accounts, the problem was solved.

Try using this:


I had a linux machine create .mov files and they worked on linux and windows, not the mac. When I converted, from mov to mov they worked.

Did you try installing The Perian Plugin for Quicktime? That may enable you to open and export with Quicktime.

(For you Mac users out there)

After spending a few hours trying to solve this, I quit.

My Sony digital video cameras create .mov files, which iMovie, iPhoto and Quicktime all refuse to open (unsupported file format) in OS X 10.7x (or 10.8x).  Cheating, by changing the file extension, doesn't help.  I'm trying to find the quickest, simplest way to convert these files - so teachers can use the cameras and work with iMovie '11.

Can do it via VLC's Streaming/export wizard, but this is NOT for newbies.

Any "free" app for this (and I tried LOTS of them) come with watermarks or other serious limitations.

Freemake Video Converter is Windows only.

Toast will do this, but it's not free.

I spent a lot of time in the Apple forums, and have now run into a dead end.  Advice?  Again, I need this to be extremely simple for classroom teachers (otherwise, I'll be spending a lot of time converting files for everyone).
