I would like to use four cameras for instant replay sources on my vMix Pro 20 software. I have a new rig that has lots of power and storage to support this. My camera setup for IR is as follows:

Two cameras are PTZoptics 20x SDI that have been upgrated to NDI and I will try to use via NDI. I currently have these cameras set to 1080p60.

Another two cameras are Canon XA25 that are set to 1080p59.94.

When I try to add these four cameras, I get an error from vMix because the framerates are not exactly the same - 59.94 vs 60. I am hoping there is a way to get past this? Any tips/ideas would be most appreciated! I would really like to keep the 1080p60/59.94 setting.

I am not a framerate expert by any means, but I did some research and I think that 1080p60 and 1080p59.94 are essentially synonyms. If so, is there a way in vMix to rename the framerate on two of my sources so that I can make vMix "happy" that both are the "same" and vMix will then allow all four sources into the IR session?

Thanks, Bruce
