p.1 #1 · Anyone had luck external recording 4k30 on Z30 for longer than 10-15 minutes?
Just picked up a Z30 to play around with. I often need a BTS camera that can run for at least an hour, and this seemed like a good solution. So far have tested all of the below powered by a USB power bank.
4k24, internal recording to V90 SD, power by USB power bank: Full 125 minutes without issues, no overheating warning.
4k24, external recording to Ninja V ProRes HQ: Full 125 minutes while simultaneously recording internally to SD
The problem comes when trying to record 4k30 internally as well as externally to the Ninja V. The camera will shut down after about 10-11 minutes and show an overheating warning. Additionally it seems like the power draw when recording 4k30 is a bit too much for my powerbank, as it will dip into the red bars even when plugged in.
I have an ENEL25 dummy battery + AC adapter coming to see if it will help with the overheating. Wondering if anyone has had any luck recording longer clips in 4k30. I don't think I care enough to go the Ulanzi fan route for the back, because I will be using the camera in 4k24.

It's interesting how big a difference you're seeing in run times between 4K24 and 4K30. My first guess is that it's data-load dependent then, ie the additional data from 6 more frames/sec pushes the data handling past a thermal budget. One way to potentially characterize this would be to film 4K30 using a featureless target, for example the lens completely OOF pointed to a bare wall. Nikon's encoder is highly variable to detail, so this should dramatically reduce the video file size. I'd be interested to see if this increases the 4K30 runtime. Note this will only reduce the data load at a portion of the pipeline, but might be an interesting clue nonetheless.
