![]() Perhaps there is something intentional going on, where in the event of the 12x12 not sensing an acceptable reference input, it reverts automatically to referencing itself to input 1, so as to at least enable clean switching (as long as input 1 remains stable, itself). To my way of thinking, the 12x12's output timing should ALWAYS IGNORE the timing of its inputs altogether, and lock only to its genlock reference source input, otherwise an unstable input 1 source would destabilize all outputs of the 12x12 at once, with a devastating outcome for any production being run through it. (I suspect this arrangement causes some vertical phase delay of the 12x12 outputs compared to the other genlocked sources in our system, as ATEM PGM out is probably not phased too closely to the system reference.) We did a couple of international sports OBs this way and got away with it, with no observed issues. ![]() So to use it as a "box of synchronisers", we have to feed ATEM program SDI output into the 12x12 input 1, to provide a synch reference. ![]() I was surprised to find that our 12x12 appears to effectively genlock its outputs to follow the synch of its first (SDI) input and NOT that of the reference input provided (PAL analog black, in our case), which appears to have no genlocking effect, whether or not it's plugged into the 12x12. You can even use the available iPad app to change routing over your wireless network.I've tried using our 12x12 Cleanswitch as "a box of frame synchronisers", so we can present its outputs as genlocked sources to our main router and ATEM switcher. Routing can also be controlled using dedicated remote panels or over Ethernet using the included software for Mac OS X and Windows. A built-in LCD lets view your sources directly on the router itself, with simple push buttons and spin knob provided for control. ![]() Housed in a 1RU frame, the Smart Videohub ideal for use in both large broadcast systems or portable mini racks for live productions. It supports 4:2:2 and 4:4:4 color sampling and 10-bit processing for smoother gradations. ![]() The Smart Videohub 12 x 12 6G-SDI from Blackmagic Design is a mixed format router with 12 6G-SDI inputs and 12 6G-SDI outputs for routing any combination of SD, HD, Ultra HD 4K, and DCI 4K video. ![]()
