The first thing to check is whether your conferencing application supports 4k video (most do not). To get 4K video with Rally, the following is required. 1. A USB 3.0 cable, 2. A USB 3.0 interface on the computer. The computer must be connected to the Display Hub to transmit 4k video from the camera. A computer connected to the Table Hub will transmit 1080p video from the camera.
4K video must be supported by both the operating system and application you are running in, as well as requires a 4K monitor. Please check with your software vendor for that support.
If you use the video capture application that supports 4K (e.g.,. Camera for Windows 10 or SwiftCapture 1.0.2 for Mac OS) you can record 4K video from your Rally to your computer. You will need to use a 4K video player on a 4K-supported monitor to properly playback your captured video (ex. VLC for PC or Mac: http://www.videolan.org/vlc/index.html).
To take advantage of 4K with your Rally, you’ll need to have a system with the following requirements:
USB 3.0 Port — Allows for more data to be transmitted (5gb/s compared to 480mb/s with USB 2.0).
Application support for 4K — Some applications will require additional codecs to support 4K resolution. Consult your application developer’s website or help resources for more information.
4K monitor and supporting drivers — Make sure that you have a 4K-capable monitor and the drivers to support 4K resolution. Consult your monitor’s manufacturer website for more information.
Windows 10 — Windows 7 supports a maximum resolution of 1080p/30fps and is not capable of 4K resolution.
USB host controller fully updated with the latest drivers
Other 4K considerations
While many video preview tools are great at presenting/decoding 1080p at 30fps, they may take a little more time when presenting/decoding 4K content as it requires a lot more resources.
You may also experience performance issues when using a video player to view 4K content. You’ll need to make sure that the player is set up with the correct codecs and the settings to decode 4K content. You should also consider that processing 4K content takes a lot of Graphics Processing Unit (GPU) and Central Processing Unit (CPU) resources.
