Rode NTG-2 audio recording not picked up on mobile devices
So I just finished editing a video which includes some voice over. I recorded the voice over using a Rode NYG-2 shotgun mic, which is a great mic. Once I uploaded my video to facebook via my laptop the video played perfectly, but when I watched it on my mobile device, any audio recorded by the Rode was not properly picked up - the same happened when uploaded to YouTube.
Somebody please help!
