Hi,

We often switch camera / video player / picture / power point ... to send at the same time to :
-> 2 screens in venue (16:9 or 21:9)
-> streaming platform (16:9)
-> facebook (9:16)

... and/or multi language power point to the language in venue + several video streams, each with its own language on video & audio.

Today we're using
• Output 1 : output "dirty" <- Stream
• Output 2 : output "clean" <- Record
• Output 3 : overlay 3 <- screen 1 (left) in venue
• Output 4 : overlay 4 <- screen 2 (right) in venue

When we select an input with multiview/layer of 2 sources
-> multiview is seen in output 1 / stream
... but with trigger, as soon as multiview is selected, the left picture is seen in screen 1 (left) in venue by activating overlay 3 + the right picture is seen in screen 2 (right) in venue by activating overlay 4
(changing the source for output 3 and 4 by triggering output settings has more delay than adding a overlay in cut direct with 0ms)

It seems vMix 26 would have more Mix output ; but it will be great if more overlay will be added (8 total or 12 if possible)
