Are you sure about the clasification? From what I heard the main issue is often cooling. Cameras and sensors are often not engineered as video capturing devices, so recording time needs to be limited to prevent overheating. Often you cannot just stop and re-start the recording after the recording limit, because the camera is still too hot, it will stop recording after a few seconds. At least this is how it works for Fujifilm X-series cameras (which have higher recording limits though and are frequently used as hybrid cameras for video recording jobs).

Well, it was what was explained to me by a marketing manager. The cooling thing hasn't been an issue for many years, since they changed their sensor design. Might also be a power-consumption thing, as the shutter needs to be kept open (I don't think they are using virtual shutters, yet), as well as (for DSLRs) the mirror.

  I don't know much about the topic, but I noticed this the other day: https://www.diyphotography.net/this-guy-liquid-cooled-his-canon-eos-r5-and-beat-the-8k-overheating-issues/ https://www.diyphotography.net/this-guy-liquid-cooled-his-ca...

    There's definitely an issue with any kind of electronics and heat. "Hasn't been an issue" doesn't mean "won't blow up when overclocked." That said, astrophotographers like to cool their sensors, because it reduces noise.

(https://www.dpreview.com/articles/6779714320/cipaeustatement https://www.dpreview.com/articles/6779714320/cipaeustatement). I have a Sony A7S2 which can do, after the jailbreak, over two hours without breaking a sweat (never went above that because I didn't need it). The exception is anything involving sunlight - there the A7S2 runs into cooling issues without a sunshade.
