QuickTime player only recording 10 seconds of video footage

I am trying to record video footage from my iPad Air within QuickTime Player (10.4) on a MacBook Pro Running OS X Yosemite (10.10.3). As soon as I press stop to finish the recording the timer shows 10 second of footage even though I have recorded more than this. It's not buffering or saying that it is finishing recording and storage is not an issue as I have plenty of storage left. The recordings I am trying to create a very short (only a few minutes or seconds long). Even more frustrating is the fact that this does not happen every time I try to create a recording. Sometimes it works and will show the full recording and other times just a few seconds. I seriously need to get this issue resolved as I am creating the recordings for my job (I work in local government). Is there anyone out there who can shed light on this issue? Many thanks in advance.
