I don’t think these values are wrong, they are ver weird indeed.
I can play the file in VLC
I can encode the file into an mp4 container, and QuickTime player plays it fine, also telling it’s 1000fps
I can also encode and force to 25fps and I do see a lot of frames are dropped, after that the file still plays fine in QTPlayer and also in VLC and Mplayer.  
Uploaded the file for you http://we.tl/SB3ZcOe8Ex
