Setting Up Your Wireless Network
When setting up Switcher Studio, there is one step that you must take before launching the app each time.
First, you must go into your general iOS settings and connect each device to the same WiFi Network. This allows each of your devices to see one another when you open the app so that they can wirelessly sync to the main device.
Two routes to keep in mind:
A Local Network used for communication between the devices.
An Outgoing Network (for uploading)
If you are recording only and do not plan to stream, then all you need is a local network with power (no need for an outgoing internet connection). In this way, you can plug in a router or use your hotspot as a means to create a bubble for communication between devices.
However, you may run into the following limitations if you don’t take appropriate steps ahead of time:
Problems syncing devices.
Poor quality between devices.
Limited distance between devices.
WiFi isn’t magic. If you don’t have a good wireless connection, your video quality and overall product will suffer. To get the best signal and video quality, we recommend the following:
Use a 5GHz WiFi router when possible. Older 2.4GHz routers are more prone to interference and slower connection speeds.
Avoid using an open or public wireless network. You want to be able to control as much of your production as possible. Having your own router specific to your production will help limit surprises, especially when shooting video off-site or on-location.
Position your devices near your router or access point.
If your video setup is not near the primary access point, consider running an Ethernet cable from the outlet or network switch and setting up your router at the center of your production.
Make sure you have a line of sight between your devices and the router. If your router is on the floor or if there are walls in the way, it will have an impact on your connection speed and throughput.
Check your router settings and make sure the appropriate ports are open. Also, make sure that “Wireless Isolation” is disabled, as this can prevent devices from appearing inside of Switcher as an available input. You will also want to make sure that “TX Bursting” and “Frame Aggregation” are turned off, as these settings can result in extreme dropped frames if not properly managed.
The most important key to working with WiFi is to test in advance. If you are going Live, be sure to set up your gear and test your connection's stability ahead of time. This is especially important if you are shooting video at a new or different location that usual. If the venue or location has a network admin or IT contact, be sure to let them know what you are trying to accomplish and arrive a day or two before your event so you have time to make adjustments if needed.
