Professional Connectivity: 12G-SDI and HDMI 2.0

Today's workflows demand speed, bandwidth, and simplicity. Io 4K Plus supports 4K, UltraHD, 12G/6G/3G/1.5G-SDI, Dual Link SDI, HD-SDI, and SD-SDI, as well as, UltraHD and HD over HDMI 2.0 for both capture and output. The HDMI output is also able to accurately display HDR 10 and HLG to support HDR workflows.

12G-SDI and HDMI 2.0 bring power and simplicity to your projects with the ability to use single cables for both input and output for the most demanding workflows. 12G-SDI is backward compatible with SDI sources, covering all your bases through a single port. HDMI 2.0 allows high raster and frame rate capture and the ability to display the same to affordable and beautiful HDMI 2.0 displays.

4K Closed Captioning Support

AJA Control Room

• Supports CEA-608 or 608-in-708 via ANC extraction firmware

Avid & Adobe Plugins

• All SMPTE-291 (ANC) based captions supported
• Adobe Premiere supports native 708 if the raw data is available. For instance, in the Adobe plug-ins, we handle the case where Premiere hands us full 708 data, we just pass it through to the device
• Avid Media Composer supports active video ANC (line 21) or ANC via ANC extractor/inserter (up to UHD/4K)
