Hissing Sound On Canon EOS 90D Videos

[krissberg]

Hi everyone, new EOS 90D user here so pardon my ignorance.  

I bought a video kit from Amazon: https://www.amazon.com/gp/product/B0101S2NU0/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1

I set it up in a studio with a lot of lights and a tripod.  The video is just me talking in front of a green screen, so there's minimal lense movement/autofocus going on.

When I play back my videos there is an audible hissing sound, like white noise, on the track.  Oddly, I swapped out the directional mic for a lavaleir mic, and the mic didn't pick up any sound. But the hiss was still there. That tells me the sound is coming from the camera?  I have my cell phone and an ipad set up teleprompters next to the camera, could it be from those?

Is there a setting or something I am missing?  I can remove the hiss in post but I'd rather not have it at all obviously.  Help!

The interference could very well be coming from your devices. You can also try turning off IS in the lens.

I thought that might be the case. I need them for the teleprompter, would switching to airplane mode help?

First, move them away and see if it is the problem.

thanks for this, a new lavalier and putting other devices into airplane mode helped!
