Note - all ATEM switchers are fussy about HDMI cable lengths.
Anything 3M or over should really be Fiber Optic HDMI cables.
Thanks SO MUCH for this Gavin!!! I've just been watching the ZV-E10 flashing away in port 3 and swapped out the 5M cable for a 1 metre cable and the sympton went. When I plugged the 5M cable back it's now OK - whcih is weird. I don't think I can send 30p to from the cameras which is a shame so I'm going to get 3M cables for the two Sony's as the Pananasonic is OK with 5M. The 5M cable, even though now working, does take longer for the picture to show so you are definately right. All the cameras work fine with a 5M cable plugged into another 5M cable on a HD TV, but I assume the ATEM is more sensitive.
Thanks so much!!
Cheers
