Why doesn't the video I recorded on my iphone want to play? - 1

I recorded a 2 minute video on my iphone 4 but I doesn't want to play. When I go into my camera roll the video is all gray and it says 'MOV' in the middle. Then when I click on it to play the video it says, "The operation could not be completed." Is there a way I can view the video?
How can I fix it?
This is a really important video to me. Does anyone know how I can fix this and why it happened?

Try to work it on PC, even convert the video format, if still not work, maybe the recorded video is wrong made.

  • Windows Movie Maker won't let me use a video I recorded with my iPhone 4? Why not? I open Windows Movie Maker, and I browse through my pictures/videos and it's not there. Every video I have with my webcam is there, but none of my videos with my iPhone is there. And I don't want to upload the video straight from my iphone because I know the quality will end up being terrible. What do I do?
  • Why can't my iPhone play my recorded videos? I recorded some videos this morning and I can't see them. It's just a white square. I'm assuming it's because my storage was full. I freed up some space but I still can't see them. Is there anything I can do about this?
  • Video I recorded on my iphone disappeared? I recorded a video on my iphone(4s) and then went to press the stop recording video but then the screen went to a grey color and a loading sign, kind of how it is when it is in the process of shutting off. I had full battery so I don't know what the problem was. A second later it went back to the home screen. When I looked at my phone pictures, the video wasn't there. What happened? I thought I pressed the stop recording button but it is not in my files
