The 29 minute, 29 seconds, 29 frames video limitation is due to European tariffs. Devices that record longer than that in the EU and some other areas are considered video cameras and have a different tax rate. However, Nikons with full frame sensors are notorious for overheating.

If you want a full frame hybrid (stills+video) camera that does not overheat, get a Panasonic Lumix S1H. It has unlimited recording in all shooting modes, same as the Lumix GH4, GH5, and GH5s. (Panasonic paid the tariffs where applicable.)

aberthet, another--probably easier--way to do that is to use your smartphone as your webcam for zoom. Google search for "using smartphone as webcam." You'll find several different apps can work.

Using an Android phone would be a good alternative, especially with the newest models having excellent cameras.

I quickly discovered that connecting my D850 to a computer (iMac or PC) was more complicated than just connecting an HDMI or USB cable. The iMac doesn’t have any HDMI ports (at least mine doesn’t). Anyway, most computers having an HDMI port is only for HDMI-OUT, mainly to connect to your television and use it as a 2nd monitor, albeit a much larger one.

The only way to use a DLSR as a video source for streaming or recording (on the PC) is to purchase an interface (Cam Link 4K, or Blackmagic Design UltraStudio mini recorder) that will plug between one of your USB-3 or -C on your computer and to the mini-HDMI port on the camera. Moreover, OBS Studio, a software app, will have to be installed on your computer.

All of that is too expensive for what I’m trying to accomplish, I’m not a pro Vlogger just an occasional one. So, my Samsung smartphone may be just the right solution. It’s paid for and has a very good camera, it’s mobile, and has no arbitrarily filming time limit (if connected to a charger).

Do a search on YouTube for videos on using a DSLR as a webcam. There are a number of them that will show you how to do it without the need to purchase a video capture card. See link below.

The free Zoom app limits to 40 minutes for 3 or more participants, but the paid ones do not have any limitations.

For 20 years, in southern California, I have looked for affordable ways to add additional un-manned video inputs to live webcast video mixers like Tricasters or Black Magic Design mixers. My workflow was 3 manned pro camcorders into a mixer which always had more inputs.

Possibilities were DSLRs, USB Webcams, Security Pan/Tilt cams, Consumer Camcorders, etc.

Some DSLRs dummy down the HDMI signal to less than standard size.
Many DSLRs leave a status overlay on the HDMI (not clean)
Elegato is a good quality hardware conversion box, but more expensive than a good USB WebCam. Other external boxes are from companies like Roxio, Hauppauge, AverMedia, AGPTEK, etc
Internal HDMI PCI cards are from Black Magic, AverMedia, etc.
Research “HDMI Capture Cards”
Research “Gaming Capture Cards” and open source addons to OBS mixer.
Research “WebCam Emulators” Sometimes you want to have a DSLR HDMI signal to be recognized by a webcast or teleconference software like Zoom. A software Emulation program like ManyCam was a workaround. Zoom’s recent security updates defeated the ability to see ManyCam, so use an older version prior to April 2020.
