If it's because of not recording overlay then is admin mistake all overlays are recorded. In this video
(HERE) you can see all overlays and another video is like just after 5 minutes of first and both recorded by same software.
I have full pov (unedited ) as well . And about not recording system sound idk why and I yes today, ocam didn't record system sound when external headphone is connected. Which I didn't know and I think not recording sound is not something that admin needs to do investigation as it's just a invalid pov.
Thank you for your time ,
And have a great day
