Since I connect my audio to my Atem Mini directly through a Mix Pre 3ii, I wanted to check the difference in latency between the Wireless Teradek Spark 4k and NDI.

Here are the Latency Results:
0 frame - Sony HDMI
.5 frame - Teradek Spark 4k (wireless!)
2 frames - Canon HDMI
3 frames - Birddog Flex (Cat 6)
4 frames - Sienna NDI app on Apple TV 4K (Cat 6)

4 frame difference is imperceivable to most people, so I didn't do any adjustments in the MixPre or ATEM Mini Extreme ISO.

Here are the links to the products I used:
