Can’t get video over 10 minutes

So basically I was finish editing my video and I was about to get it uploaded to YouTube but I noticed something on the minutes, which it was supposed to be over 11 minutes but instead it was about under two minutes which i didn't do that so I tried to import it again but it still happened. So I checked the original video and it was over 11 minutes so I'm confused why it cut most of the video in half. Can anyone help me with this?
