Nikon Coolpix corrupted .mov video file repair

[darrenpj]

I have Nikon Coolpix P300 camera that saves videos in the .mov format.
One of the videos ( 1.7 GB) got corrupted because the camera got shut down before video recording got stopped.
I can move that file from one location to another but I can not open it with any player as it got corrupted.
Spent few hours already on Google looking for a .mov repair utility for Windows and tried some but no success. Mainly because those self-proclaiming "repair" utilities are nothing more than simple undelete (recover) utilities.
I've also tried the Grau Gbr utility that was suggested on VideoHelp somewhere but that tool is not supporting Nikon Coolpix .mov format yet.

Is there some other .mov repair utility that may work?
Thanks

hex editing the file header sometimes works if you replace it with a known working one. other than that mov files suck to work on as they use an atom that isn't written until the file is closed.

some folks say this works - Video Repair Tool - but it's not free. it may have demo version to see if it might work.

[edit] sorry didn't recognize that as the same tool. you are most likely out of luck and may as well delete it and move on.

Thanks for the reply.
I can not say though what I've heard had cheered me up I was hoping some "magic" utility would solve it for me.

Would you be able to send me somewhere where editing the hex header for a situation like this is explained in more details and what tool to use?

you need to open a couple good working videos from the camera with a hex editor and find the header part that's the same and copy and paste it into the non-working one.
