Agile Input Routing expands number of I/O

Input/output functions of KAIROS has been expanded and strengthened by the "Agile Input Routing" feature that flexibly allocates GPU I/O capability according to the bandwidth of video source.
For example, via the ST 2110*1 network, a single mainframe Kairos Core 200 can simultaneously connect up to 64 inputs/40 outputs*2.
This allows using in larger scale live productions with more scenes and more input sources.
KAIROS removes input restriction to be connected to a system and realize more efficient use of ST 2110 network and other inputs such as SDI, NDI®, SRT and other streaming inputs.

  • *1: AT-KC200L1 will be supported in the future.
  • *2: Requires KAIROS Software V1.6 or later.

Processing by the GPU for flexible video expression

Layered effects with unrestricted number of MEs

Unlike the conventional hardware-based switcher, KAIROS is unrestricted by the number of MEs or keys. Layers can be added as the GPU capacity permits similar to the layers of a standard image-editing app, allowing you to set the keys and scaling freely.
The Kairos Core 200 in particular has significantly increased the number of layers by increasing the GPU video processing capacity to enable more complex and advanced video expressions.
System software V1.5 includes 2.5D DVE support (rotation and position adjustment using X, Y and Z axis).

Various video effects using layers

Diverse effects with title generator

Layers can be added with not only keys but also various effects. The built-in title generator allows you to create titles.

Format-free Canvas

The Canvas function enables the production of videos in a special format, such as 32:9 for wall display, in addition to the standard 16:9 format. Up to 8K (32M pixels) resolution is supported. With the freely customizable multiviewer, videos with unique aspect can be displayed as is.

The multiview displays a 32:9 format screen

Short one frame latency and variable frame delay

The KAIROS processing latency can be as low as one frame. Sports and concert performances can be presented with the action intact.
A variable frame delay (1 to 20 frames per 1 frame step) can be conducted for each channel, and the frame delay difference between the sources can adjusted.

The KAIROS processing latency can be as low as one frame.

Video/audio/still picture file retention

With the built-in RAM Player, Clip Player and Audio Player, footage can be played loaded video/audio files. A playlist function has been added to the Clip/RAM player. It also has a still picture storage. System software V1.5 enables KAIROS input/output video to be captured as still images as well as video clips on the RAM Player.

  • RAM Player (8 channels, uncompressed)

    Uncompressed images can be played, making it suitable for playing relatively short videos such as background video loop playback and flying logo. The recording time depends on the RAM capacity of the Kairos Core 200, and increases according to the material image resolution and number of channels (up to 8 channels). Clips are imported externally and saved onto the internal SSD.

  • Clip Player (2 channels, compressed)

    It is possible to play compressed video files with audio, making it suitable for playing relatively long clips such as commercial footage. Clips are imported externally and saved onto the internal SSD. It supports AVC-Intra, H.264, and Avid DNxHD video file formats. In addition, Apple ProRes* is supported.
