Recovered .mov file cannot be played

I tried converting video using Micro Video Converter on mac pro somehow it didn't convert and the .mp4 video file from my SD card became invisible. I recovered the file using some recovery software from my sd card and it was recovered as .mov video file instead .mp4 video file and it doesn't play in any video player. I recovered many files but none of them cannot be played. Any suggestions on what I can do or where I could take the data to fix it would be greatly appreciated. Let me know if I can provide any other information to assist in the creation of a solution. Thank you in advance.
