We often use the vMix Instant Replay system to generate replays during sports events. Our vMix setup is connected to an external MIDI controller, and we make extensive use of multiple Instant Replay shortcuts.

One key difference in our workflow is that we use a custom approach that we find easier to operate and more similar to the EVS-style Program/Preview output workflow.


When operating replays, I usually switch between the A and B replay channels using the "Swap Channels" shortcut. However, in vMix the actual output remains on a single replay output (Output A only).

What is happening in our workflow is the following: we switch from Replay A to Replay B while Replay A is set to be on air. We then change the camera angle using the ReplaySwapChannels shortcut. This swaps the angle from A to B, but it does not switch the vMix output from Replay A to Replay B.

This behavior is actually what we want, and it works well - however, it only works with a CUT transition, not with a FADE.

I understand that a fade transition normally works when mixing Output A and Output B and switching between them using a fade shortcut or play events function . My question is: is it possible to apply a FADE transition to the independent ReplaySwapChannels shortcut, where only the replay angles are swapped between A and B, while the active output remains on Replay A and does not switch output from A to B?
