FREE multi-channel capture tool, IngeSTore


Bi-directional I/O’s provide unrivalled flexibility

  • 8 bi-directional HD-BNC video connectors supporting 3G/1.5G SDI I/O

  • Multi-channel 4K UHD 60p playout or capture video Quad Link 3G-SDI

  • Each BNC is completely independent

Maximum connectivity

  • Reference I/O BNC

  • LTC I/O

  • Interlock between multiple K8 and Epoch | Neutron/4K Neutron cards

Optional connectivity

  • Optional auxiliary I/O can be added to K8 via the STEM port interface and optional EX-1 and EX-2 products

  • K8 with EX-1 adds LTC I/O, RS-422 control and AES audio I/O

  • K8 with EX-2 adds LTC I/O, RS-422 control and Analogue audio I/O

The industry’s lowest latency I/O, by design

KRONOS K8 has, by design, the world’s lowest-latency providing access to captured fields or frames to on-board card memory event before the whole field or frame is complete, thereby reducing the latency to sub on field or frame. During a capture or playout, each process can occur at less than or equal to 1 field for interlaced modes, and less than 1 frame for progressive modes.

Maintaining a 12-bit processing pipeline

  • 12-bit image processing is standard on all Bluefish video cards

  • Allows 8, 10 & 12-bit SDI video signals to be produced from 8, 10, 12 & 16-bit pixel formats providing the highest image quality available from your source material

  • 4096 discrete values of red, green & blue are maintained per pixel

  • 4 times the colour precision of a traditional 10-bit processing pipeline!

Maintaining the highest quality RGB <=> YUV

  • Fully programmable 4 x 4 x 33-bit colour matrix providing the highest quality colour space conversions

  • Reduces colour space conversion errors and ensures the highest quality colour accuracy during capture, monitoring and mastering

Thunderbolt expansion chassis compatibility

Low-latency video keyers

  • 4 x Low latency hardware video keyer

  • Allows video layers to be combined in hardware with microseconds of delay

  • Enables animated logos, captions, tickers, and more to be keyed over live video feeds at full 12-bit precision, and with minimum input to output delay

  • Can also function as an image pre-multiplier to assist in previewing images with alpha data
