In our church we are using PTZ camera's with a nice slow pan, but the mimimum zoom speed is too fast for using in live shots.
What I am asking for is the possibility to zoom the program output on-the-fly with a shortkey.
The intention is to zoom in just a little and very slowly with an atmospheric effect before switching to the next camera.
Zooming should stop automatically after changing the output.

Maybe this can also accomplished with an extra transition (only zoom in and then cut/fade), but the duration should be longer than the maximum of 9999ms.
In this case activating the cut/fade moment by selecting the transisiton again would be very welcome.
