Video/file Repair Software

Hello Tek Syndicate, I recently purchased a helmet camera (Go Pro Hero 3) and in a rush forgot to format the memory card before using it. We filled the 64gb Sandisk micro sdxc with video from a trip and when I put in in my pc it asks me to format the card and I practically shit myself. 

I used iCare Format Recovery 5.3 and Stellar Phoenix Photo Recovery to get the information off the card but now I have a bunch of corrupt mp4 files... and a mov file that do not play. So I tried Do-It-Yourself Video Repair Software (thats the closest thing to a name I found for it and it seemed to have a high success rate but I had no luck. 

I have not formatted the memory card yet. As of now it is a brand new card with files written to it, is there any way to save them?
