Major video latency on the Atem mini

Hi guys I just got my ATEM mini for drum teaching online.

I'm using three cameras, all gopros, one gopro6 and 2 x gopro 7.

The video on the gopro 6 seems fine but the gopro 7s are waaaaay off. About a 1.5 - 2 seconds delay.
I'm a complete beginner so it could be something very obvious!

Any help welcomed :]

many thanks

James

Are all the cameras in the same resolution?

And did you set the output resolution in the ATEM?

It's best if all the inputs are in the same resolution as the ATEM and each other. That way the scaler/converters are all running the same throughout the system. If the ATEM has to do a bunch of of conversions, it's going to add latency to signals it has to do more processing to to get it in line with the rest of the system.

Hi thanks for the reply.

Excuse my ignorance but how do I set the output resolution on the ATEM?

Many thanks
