You have one camera and you want two. The first search result tells you to buy a switcher, and the price is more than the camera. That is the traditional answer and it is no longer the only one.
What a switcher actually does
Three jobs: it takes several video inputs, it lets you choose between them, and it outputs the chosen one. Every part of that is something software does now.
The genuine advantages of hardware are frame-accurate switching latency, not needing a computer, and long SDI cable runs. If none of those is your constraint, you are buying a box to do a job the computer can already do.
Four ways to get a second camera in
- A USB capture stick. One HDMI camera, very cheap, plugs straight in.
- A multi-channel PCIe capture card. Four, eight or sixteen inputs on one card inside the machine.
- A phone over Wi-Fi with a companion app. Free, and the sensor is better than people assume.
- A small network encoder for a camera too far away to cable.
The multi-channel card is the purchase that replaces the switcher outright. Every camera plugs into it, every camera arrives as its own source, and you switch on screen.
What it costs, roughly
A single USB capture stick is the price of a meal out. A four-input card is a fraction of a switcher. A phone is free.
Put another way: a venue that spent twenty-one thousand rand on a switcher, seven on an encoder and seven on a recorder could have had a capture card and software instead.
Switching properly once it is in
Having two sources is not the same as cutting between them well. Use Preview and Programme — line the next shot up privately, check it, then take it. Never cut straight to air.
Hold each shot longer than feels comfortable. Four to six seconds minimum. And match the two cameras for colour before you start, because the cut between a warm camera and a cool one is the most noticeable thing in an otherwise good broadcast.
The part you gain by skipping the box
When the switching happens in software, the other capabilities are already in the same place. In Skynat Live that means each camera can be colour-matched, run through a full audio console, recorded to its own isolated file for editing, and replayed in slow motion — none of which a switcher does.
Up to twenty sources in any combination: cameras, phones, media, remote guests.
