I'm using Camtasia 2.10.8, on a 2017 Macbook Pro running Sierra (10.12.6). I just recorded a 5-minute video with screencapture and webcam. About 2 minutes in, the webcam froze. Of course, I didn't know that until I finished the recording. The audio and screencapture were fine. So, I split the webcam video into an independent track and deleted it. I've done this kind of recording a lot, on my previous Mac, but only a few times on this new machine. No problems with it prior to this. Is this a known issue with newer hardware? It just seems weird.
