Can you stay longer in Live View, using an external monitor, on a d850 than d810?

When I'm shooting video on my d810 using an external monitor via HDMI, Live View shuts down after about 10 minutes (faster under very hot lights). I've talked to Nikon (and some of you) about it at length, and there's nothing wrong with the camera; it's supposed to shut down to protect its inner circuits.

External recorders are not the solution either, as they depend on the camera's Live View.

So, does anybody know if d850 can stay longer in Live View than d810 during video recording, using an external monitor? I ask because I could imagine d850 might be more robust in handling high temperatures, given it's 4k (I'm staying at 1080p, however).

And if not, does anyone happen to know if Sony A7r iii might be better at this? (I'd prefer the Nikon, but I simply need a reliable Live View feed.)

Thank you!

Can you stay in live view longer if you're not outputting to a monitor? On my Nikon D7000, the built in screen goes blank when I plug-in a monitor, and I can shoot for at least 30 minutes, but I was using LED lights that don't generate much heat.
 
Your experience with the D810 still doesn't sound right to me. I shoot with a D800 which I realise is different but I have recorded the output to a Blackmagic video assist for over an hour without anything shutting down. I find it very hard to believe that your D810 won't do this despite what Nikon say. Have you tried an external recorder to see? If I just run Live View without recording internally then it does shut down within 15 minutes but if I record internally it runs to 19 minutes 59 seconds before shutting off but that is nothing to do with heat issues. It is to avoid taxes that would be incurred if it ran longer because then it is classed as a video camera. Are you saying you cannot record internally for longer than 10 minutes without it shutting down?

Hi again, thank you for your reply! An hour would be friggin' awesome, and I'm definitely puzzled about these inconsistencies. No, I haven't tried external recorders, but I did ask Atomos as well as Blackmagic about their products and both said that they depend on the camera's own Live View. Here is what Blackmagic said:

"the Camera will always have to be in LiveView mode as this is a camera function. It takes allot of battery and image processing to run two screens, so the limitation is usually 10minutes or shorter depending on the camera"


So that didn't exactly inspire me to buy one...

Yes -- and more than that: When I shoot stills, I can't stay in Live Mode for long either (still connected to the external monitor). I haven't timed it with stills, but again, it depends on the temperature: Many lights = shorter period of time in Live View. I guess I can stay for perhaps 15 minutes. But it'll shut down after 5-10 minutes during the next session after that because it's hot already.

Hi Imamacuser, thank you for your reply!

Yes, I can stay longer without the external monitor, but unfortunately I do need that. It's definitely impressive that you can shoot for half an hour with the D7000.
 
You need to rent an external recorder and find out for yourself because the manufacturers won't comment on two differing companies products working together. What Blackmagic said to you does not fit with my experience albeit with a D800. Half the point of these recorders is to defeat the 20 minute recording time limit. If you are anywhere near me in the UK I will bring my gear and you can try it out and get to the bottom of this.
The only reason my time limit was an hour was because the show finished!
The D810 manual on page 62 tells you what the maximum recording times are for internal recording. 1080p 25/30fps at the highest bit rate is 20 minutes. At 50/60fps it is 10 minutes. Maybe that is what you are experiencing. I am still confident that would be irrelevant with an external recorder.

Thank you very much for your kind offer! I'm not even on the same continent though :) so I'll find another solution. Yeah, it's confusing, that's for sure (I've always recorded at 30fps so that shouldn't be the reason, either).

The worst part? I've just spent 3 hours watching d850 stills and videos. THAT was a bad idea. :(
 
The hdmi cable limit is 5 meters I think so the different continent thing is a problem:-)

If you're doing long takes, you must set CSM #C4 Live View to No Limit on the D800. Maybe you have something similar on the D810?
 
... inspired me to check the length of the cable, but it wasn't that either.

Yeah, I've triple checked every other setting, too. So I'll reconsider a Blackmagic recorder. (OR that d850. :-)

Again, thank you for your help!

With Nikon Hackers record limit removal, I can record for 24 minutes in 1080P at 23.976 fps in NTSC high quality mode. What I meant in my original statement is that I recorded clips back to back for a half hour or so. However, I have recorded for 75 minutes straight in 720P at 23.976 fps in NTSC normal quality mode.
 
ah, yes; now I remember that we had this conversation quite some time ago.

I never could get that hack to work so I chickened out trying to work out why it wouldn't work.

Nikon frustrates me so much :(
 
I use D810's for image capture into an Atomos Ninja Flame. At 1080p60, I have been successfully recording 4:2:2 10 bit @ 250Mbps. I have recorded interviews which lasted about an hour. I set the live view display on the 810 to unlimited as some have said above. I have successfully recorded with CD/Compact cards both in and out of the camera body. I see no difference---nor is there any difference in bit rate or bit depth between having the cards in and out of the camera body contrary to what has been opined elsewhere. To be clear, I am not recording onto the camera cards at all---I press record on the external recorder and only record onto its SSD. I am using the only lens and sensor (no 4K of course) only from the Nikon. I am also bypassing the audio and sending the audio signals independently to the Ninja Flame, which is ignoring the hdmi passthru.
