Having Issues with Final Cut Pro

I am really struggling to find out what could be wrong with the video software and need help fixing and resolving it. So this is how far I've gotten.

When still the video records perfectly, no issues or problems. I record with Final Cut through my Videocamera. When I begin moving my video camera, and keep in mind it's a very simple and slow back and forth just following the speaker, the camera then begins to have problems. It will show the speaker in real time, then skip back to an earlier frame, then back to present, then back to that earlier frame and sometimes it will resolve and not mess up when having this episode but sometimes it ruins the audio and drops frames resulting in it forcibly ending my recording in general. It doesn't always do this when moving that camera but will happen at least 3 times during a 1 hour recording.

My question is what's causing this? Sense it doesn't do it until someone is messing with the camera could it be a hardware problem? Could my fire cable be malfunctioning somehow? However I never lose the signal which leads me to believe it's a software issue just not able to handle the moving of the entire picture. Could this be because my computer can't handle it? I will admit this is an incredibly old macbook I am running on, at least a 6 years. Has anyone else had similar issues and if so, how would you recommend going through to fix this problem?

Thanks in advance to anyone able to help.
