A few of the folks who have contacted me about BoinxTV after reading a piece here at ReadyMadeWeb have complained about audio static or “popping” when they switch between cameras. I’ve found that this can be addressed in one of two ways.
First, by selecting the camera you’re going to switch to so that it appears in the preview window in the upper left corner of the BoinxTV window, you place this source in a sort of “on deck” position. This means that BoinxTV while BoinxTV will not be recording that source, it will be receiving a live feed of information from that source, so that a switch will be seamless.
Failing to place a source in the “on deck” position means that the switch will be abrupt, as the source will have to be initialized before BoinxTV can start recording from that source. That’s what accounts for the static or popping sound.
Being that live production is often limited by how much human processing bandwidth you have—how many buttons, audio sources, camera adjustments, and sound mixer sendings you can pay attention to—it’s best to try to simplify where possible. That’s why I find it helpful to have one constant audio audio source, rather than tying audio to cameras. To do this, select the audio feed of one of your cameras as separate Audio Source layer (see the example above). You can then select each of your video sources and remove the audio component from them entirely—failing to do this could result in reverb-like audio as you’ll be capturing the same audio twice.
By completely divorce audio and video, the issues of static and popping from source switching should be completely solved.
