Can I remove the audio from a video on Mac without using 3rd party apps?

I am looking to share many of my videos from my vacations with communities like Pexels or Pixabay but I can't upload them since I was either talking to my wife while filming thinking I'd remove the audio in FCPX later, or there are other bothering sounds in the videos.

The videos are 5 seconds long, and are many, so I don't want to edit them in FCPX, save, then upload them, and I was wondering if there is an easier solution to the problem I'm facing, so that I can upload them without sound str8 from my Mac, without too many additional actions on my end.

Thanks in advance!
