I have a film assignment due soon and all of my videos are working and editing, the're mts files straight from my camera however one of them is playing up. it won't open using any video player except for vlc but it take roughly 20 minutes to open. It's supposed to be a 9 minute video because that's what it says on the camera but on the computer it's only 4 minutes and stops abruptly without the full content. I've tried everything i can think of but it's not working and i can't edit it. This is starting to frustrate me.

Please help
