OG-12GM Workflow Diagram 

This workflow diagram shows a 4K camera system outputting video via a 4x 3G-SDI quad-link connection. This output is connected to the 4x 3G-SDI inputs of the OG-12GM, which converts it in turn into single-link 12G-SDI, shown here with a Ki Pro Ultra 12G recording the video at the end of the signal chain.




OG-12GM Workflow Diagram

This workflow diagram shows a 4K camera system outputting video via 1x 12G-SDI connection. This output is connected to the 12G-SDI input of the OG-12GM, which then converts it into quad-link 3G-SDI, here shown with an AJA KUMO 3232 3G-SDI router providing further distribution.




OG-12GM Integration Diagram

This integration workflow diagram shows a 4K camera system outputting video via a 4x 3G-SDI quad-link connection. The OG-12GM provides a conversion from quad-link 3G-SDI into single link 12G-SDI, allowing the 4K 3G-SDI camera source to fit seamlessly into a 4K 12G-SDI eco system. Multiple OG-12GM cards can be housed in the appropriate openGear rackframe, making multi-cam conversions easy.
