![]() These types of production setups, called virtual multi-camera (or virtual PTZ), work by using a 4K camera to take a single shot of an area and then using the cropping features of the 4K encoder. ![]() By pairing a single 4K camera with a live production encoder capable of cropping, live switching and capturing 4K signals, you can create a powerful solution that mirrors the benefits of a traditional multi-camera setup. Luckily, the affordability of 4K technology allows producers to mimic traditional multi-camera production setups without needing to incur additional costs for more cameras and personnel. While advantageous for capturing different shots within a filming location, this style of camera set-up can consume significant resources-specifically with respect to set-up time and the number of operators/technicians required to operate the cameras and control the live stream. Traditional multi-camera setups ( Figure 1, below) employ several different video cameras to simultaneously record or broadcast video content to viewers. ![]() ![]() When frame size requirements for streaming and recording are Full HD or HD, 4K technology actually has the ability to reduce the cost and complexity of creating multi-camera setups for live video production. Although most practical streaming setups are still happening at 1080p or 720p due to bandwidth limitations, 4K video has much more to offer than a simple upgrade in pixel density.
