RT Software’s Engine is our core rendering technology used across all our broadcast products. It supports a wide and ever increasing range of video formats, transports and resolutions. The broadcast universe is expanding, and we are continually developing our support to stay at the forefront of emerging formats. Please ask us if you require something not listed as we may be already implementing it.
The following list covers all of RT Software’s broadcast products and includes SDI, ST 2110, NDI, and proxy previewing formats.
The quantity of video inputs and outputs is dictated by the hardware cards used (although some software and operating system limitations exist aswell). To find out what video I/O is supported on different cards take a look at our Recommended Hardware page.
If you would like to understand what files can be incorporated into your templates take a look at the Supported File Formats page.
SD – 525i (NTSC), 625i (PAL). 4×3 or Widescreen.

NDI is suitable for broadcast to air with a suitable NDI infrastructure. We also offer NDI as a preview output.
We support normal NDI (‘high bandwidth’) and reduced bitrate NDI HX (‘high efficiency’).
Bit rates for high bandwidth NDI will vary based on the format and resolution. HD signals would be in the range of 100 – 160 Mb/s. Whereas NDI HX would be between 7 and 16 Mb/s. Some useful guidance can be found here:
16bit – in development
Not currently supported.
Output Yes, RGBA
Input Yes, BGRA
Display Port (1.4)
These versions support HDR.
