Probably not. The bigger the file the more likely your continued use of the card destroyed some of the data. Once you've overwritten blocks in the middle of the video it's pretty much impossible to recover the rest of the video.

You can try some other image recovery programs but I'm doubtful that they'll be able to do significantly better. Sorry.
