I'll be streaming a live event from a remote location with a bonded internet solution next month. I'll have 2-3 cameras that I'll want to capture and incorporate as a vMix Replay workflow into my stream.

I'm new to Instant Replay so I think there are some gaps in my knowledge and haven't found an a good detailed explanation/solution for vmix anywhere online.

From my understanding, I generally have 2 options for this:

Option 1. TD and Replay Op on same computer.
This seem seems manageable with a separate replay controller and separate monitor, but having to share mouse and keyboard seems like a bit of a headache if we want to create highlights, export clips, and do any advanced stuff within any of the menu systems of replay or switching. This seems like best option for one man band operation.

Option 2. Separate vMix machine dedicated to Replay
I know this would require an additional license. This solution seems the best for managing the replays with dedicated op, but my knowledge slips considerably here.
- What's the best way to get the live camera inputs into both the replay machine and the switching/streaming machine if NDI isn't an option? Is this a hardware solution?
- Likewise, once I have camera inputs in vMix Replay, what's the best way to send an event to the switching PC if NDI isn't a good option? Is this just via utilizing an output from the PCs graphics card into an input on the switching PCs capture card?
- I know there are auto triggers, like stingers and auto-switching back to preview, if utilizing same machine for switching and replay, but all of this would just be queued and timed manually with TD and Replay Op if they are one separate machines, correct?

If anyone has a workflow environment they'd care to elaborate that is using two machines without NDI I'd love to hear about it. If someone has done this with bonded internet to broadcast in the field, then I'd be super interested to hear what that looks like as well!

Thanks!
