Production Switchers

I have not had this issue before, or I do not recall it being an issue before. I have Key 2 on ME2 set as my clean feed as that is where my Scorebug is. However when I do that I can not use Key 3 or Key 4. When I set Key 4 as the Clean feed on ME 2 I can not use Key 3. Anyone have a thought of a setting I am missing?

Not enough information to understand what your issue is. Can you take pictures? What do you mean by you can not use Key 3 or Key 4? Your title is Clean Feed on MiniME but then talk about ME2. Where are you viewing the Output that you don't see the keys? a lot more description is needed.

Les,

Sorry I am not by the switcher at the moment, but maybe this will help more.

I use MiniMe 4 as our output to our scoreboard. We do not use any of the keyers on that MiniMe and I just assign it to the CLN feed so the scorebug that is in Key 2 on ME 2 is not visible. We then switch as normal using ME2 for everything. For my normal setup I have CG 1 in Key 1 and CG 2 in Key 2. For an event we just had, I needed to assign Key 3 as a Self Key and Key 4 as a Chroma Key for some CG graphics we had. Everything looked fine on PGM, but the CLN feed to the scoreboard was not seeing anything below Key 2 on ME2 which is assigned as the clean feed. If I assign Key 4 as the Clean feed on ME2 then I was able to use Key 3. Typically I do not use more then the 2 keyers on ME2 so its not something I have noticed before.

Note that I do use MiniME3 Key 2 DVE as well as a confidence feed from our scoreboard processor. Switcher mode is MiniME FCFS.

Clean feed is always the ME PGM but before the Key you have selected.
