Im not sure if you know, but i'm pretty sure you can setup the ZV-1 to not shut off shooting in 4k when its getting warm in the menu's, but I believe it does have a disclaimer for at user's risk. The Blackmagic Design Pocket is an awesome Camera. Absolutely recommend a good external touch monitor though. I have found it just a little hard to monitor with the touch screen on the back when having to adjust the camera higher or lower than the operator needs to be.
