I need to save a movie to a blob in a database and of course restore it. I thought it was working but it appears to be keeping a reference to the original movie file the user imports because if you delete the file and then try to view the movie it tries to look for the file and of course fails. I'm using QTMovie's movieWithURL to initialize the movie from the original file and using movieFormatRepresentation to get the NSData object from the movie to save to the database. When I restore the movie I use movieWithData:

I've tried using movieWithData: with NSData dataFromContentsOfFile instead of movieWithURL, but that causes my program to crash.

movieFormatRepresentation writes out only the movie atom (the "bookkeeping" info contained in a movie file, not the media data). Sounds like you need all of the movie and media data in one blob. Try writeToDataReference:withAttributes, specifying the flatten flag.
