[Q] Video Recording Shutter Sound

So my only complaint with the Axon Pro is that if you use any application other than the normal camera app to shoot a video, it has a really loud shutter sound notifying you that it's recording. It doesn't make the sound in the camera app, so far I have tested it on Instagram, Snapchat, and Facebook Messenger. There is no shutter sound setting in the camera app. My phone is on silent and it still makes the noise.

Is there any way to remove that? I'm assuming you can do it with root access once this phone is rootable.
