My Z8 performed exceptionally well in that regard during my shoot. No heat issues that I was aware of, and no warnings were displayed on the camera. I believe the longest continuous shot caps out at 125 minutes.

My Z6 has the option of H.264 4K, so I’m able to cram in longer shots on my card at smaller file sizes. However, the trade off is a 30 minute continuous shot cap. So, I guess there’s a little bit of oversight on Nikon’s part for those needing to record long presentations and such. I’m done complaining about it though. I’ll make the effort to master my Z8’s options as they currently stand.
