Canon releases statement on EOS R5 and R6 video heat management

Canon has released a statement on how heat is managed in its new EOS R5 and R6 mirrorless cameras, as well as clarification on video recording times.

Canon EOS R5 and R6: Shooting times for video modes

Canon UK & Ireland: The highly anticipated Canon EOS R5 and EOS R6, two advanced full frame mirrorless cameras, offer a combination of speed and resolution to set new standards and make mirrorless an ideal choice for everyone from wedding to wildlife photographers.
 
EOS R5 and EOS R6 offer powerful stills and movie recording capabilities within compact body designs, allowing photographers and filmmakers to push creative boundaries harder and capture action better than ever before. At the highest frame rates and resolutions, heat is generated because of the best-in-class resolution, frame rate and autofocus capability, which can limit continuous recording times.
 
Several steps have been taken to manage this; magnesium alloy is used in the body to dissipate heat away from internal components and there is an ‘overheat control’ function to reduce heat generation when the camera is in standby. To maintain the level of weather sealing and retain a compact design, an internal fan has not been installed.
 
Before recording starts, EOS R5 and EOS R6 display an estimate of the recordable time based on the current camera temperature and the set recording mode. Approximate recording and recovery times for 23°C / 73°F environments are available so that customers will be able to decide how to best utilise each mode:

EOS Webcam Utility software

Canon has developed EOS Webcam Utility software to bring easy-to-use, plug and play, webcam-like functionality to selected Canon cameras (see below for full list of compatible EOS models). This allows you to use your camera as a high-quality webcam for personal or business video calls.

The free software is currently Beta, which means that Canon welcomes feedback about bugs and suggestions for additional features. Also, it can only be used with Windows 10 64-bit at present, though compatibility with other computer operating systems is likely in the future.
UPDATE 28 May 2020
EOS Webcam Utility Beta is now also available for Mac OS – 10.13 (High Sierra), 10.14 (Mojave) and 10.15 (Catalina).

Details about compatible cameras and download instructions are available at:
