So on a Vision or an Acuity you would use the AutoFollows systems to achieve a similar result with substitutions.
There is an example where we used a DashBoard Panel to do this monitoring of the Bus and then do the substitution for you. That is one option and it can work.
Since your only trying to keep out Replays -- its normal that for Replay events we have a Replay In and Replay Out Custom Controls -- since they usually use a special Wipe transition. So they could just build it into those Effects that they change the AuxBus that is feeding your board from the ME CLN Feed to a Still or Beauty Shot. In the past we have built something similar using a MiniME so that you can even keep the wipes. We just Key the Wipe on in the MiniME Key 2 as well as on the PGM ME. So in the Custom Control we turn the Key on When we do the Wipe and then Turn the Key OFF when it turns off on the PGM ME as well.
For the Replay IN even we add the selection of the Still Store or Camera on the PST bus of the MiniME -- there is usually an event that is setting the ME the replay with run as well. Then where they run the wipe effect -- we also cut on the MiniME Keyer that has that as the source. When they insert the CUT on the PGM ME then they also Add the Cut on the MiniME. Finally when they cut the keyer off air they also cut the MiniME keyer off air as well.
Then they do the reverse on the Replay Out event -- just making sure to select the PGM ME CLN source on that MiniME.
