When it comes to Multiple Camera Angles and Live Streaming, I'm constantly impressed with the simplicity and ease of use with SlingStudio. Instead of an ATEM hardware switcher, you're managing everything from a simple iPad - wirelessly. Instead of running cables back to your switcher, your cameras are wireless and free to roam. Even though you can use professional cameras with a CameraLink adapter, you always have the option of simplifying your setup using the SlingStudio Capture app on iOS or Android Smartphones.
For those smaller productions or on location, I decided to invest in (4) 16GB 6th Gen iPod Touches. They are inexpensive new, but you can also save a few bucks if you find refurbished models. Launch the app, and the video feed is streamed right to the SlingStudio hub.
To increase run time, I threw them into an iPhone 5 battery case. The iPhone 5 is pretty much out the door, so battery cases can be picked up for dirt cheap. Since an iPod touch is physically slimmer than an iPhone, you'll need to add a little bit of padding behind the iPod to take up the extra space. Outside of that, iPhone 5 cases are a perfect fit.
In order to mount the iPod Touch, I specifically chose the Ztylus Z-Grip Clamp. This allows for a tripod mount, and also a cold shoe mount for a microphone or LED light. The clamp is also designed to be used as a hand grip if you're shooting handheld.
For better audio, I decided on the Rode VideoMicro Microphone. These microphones are small, come with a shock mount, and will work directly to any camera. But if you purchase the (optional) TRRS patch cable, then it will directly work with iOS devices too. I think the furry windscreen also makes the setup look pretty cool too.
There's a few more things i'm going to add to my ultra portable setup here such as an XLR to iOS adapter so it will give me more options to use different microphones or audio mixers. I'm excited to start putting this mobile setup to use, and if you're interested in Multiple Camera Switching for Live Streaming, check out more info about the new SlingStudio (here):
