Hi all,
I do a number of live IMAG type events where I have no more than 4 SDI Cameras and want to use vMix to live switch to the projectors so I need the lowest latency solution as possible.

I have the following laptop:

ASUS TUF F15 TUF507VV4-LP089W 15.6" FHD 144Hz RTX 4060 Gaming Laptop Intel Core i7-13700H - 16GB RAM - 512GB SSD - AX WiFi 6 + BT5.2 - Webcam - Thunderbolt 4 (DP) - USB-C (DP & PD) - HDMI2.1 - RGB Keyboard - Win 11 Home

I have got the vMix 4K version.

I am currently using UVC USB 3 devices via HDMI which work fine but have a bit too much latency.

Is anybody using the AJA IO-4K Plus or similar and if so what sort of frames latency do you get?
Is there any other device which is faster that you can recommend?

Also, is 60p still twice as fast through vMix compared to 30p? - I am not sure why that is as I would expect it too be slower as twice as much data to process?

Thanks and regards
Paul
