A cryptic message for sure but simply points out the necessity for backups. If you’re going the DIY route for your business’ content, there are times that you’ll run into some bumps in the road.
Take for example, audio in a video. If you only have one microphone, on camera, and you’re the subject in the video, you may not notice if the battery dies on the microphone. Man, have we ever been frustrated by this. When that one source of audio fails, you now have no audio.
However, if you use the same on-camera microphone and also have a wireless lapel mic clipped to your blouse or jacket, now you have two. If one fails, you still have one more good source of audio.
