Reliable software to record webcam videos longer than 5 hours? i'm doing university exams over the next, and due to covid, I have to do them at home, and record. I need to be able to record for around 5 hours continuously, - if the video fails i'll fail the exam. I've never done this before, and don't know about any software / any limits on software I have. + I don't have a camera, - only macbook.

Edit:
model is MacBook Pro (13-inch, 2018), running Mojave version 10.14.6 (18G8022)
I tested a few last year when I had to keep a watch on some people who were blocking my driveway (yeah, ikr;)
I tried a few, but the one that seemed to behave the best was SecuritySpy [approx £34, with free 30-day trial]. It can do a lot more than you need it to do, multi-camera, motion sensing, etc, but one of the simplest tasks it can do is just 'record until you tell it to stop', or you can preset 'record 5 hours' etc. It also timestamps in the corner of the video.
You can set it to a low refresh &amp; low fps so it doesn't eat your drive making cinematic quality movies, if all you need is a record of you not sneaking off to the local library or having the answers written down right next to you.
