Important Details Regarding Camera Temperatures During Video Recording

Temperature plays a major role in the actual recording times for the Canon EOS R6 Mark II. Below is a list of estimated shooting times when the rise of internal camera temperature is taken into consideration.

Estimated shooting times for the Canon EOS R6 Mark II according to an increase in the internal camera temperature
Format	Limit
¹Estimated time for continuous shooting in 23°C / 73°F environment, from a cold start. If the camera is in LV mode standby before shooting or the ambient temperature is high, the shooting time may be even shorter. ²According to Canon measurement conditions when using UHS-II cards conforming to Canon testing standards. ³ The maximum duration of shooting may be shorter under some circumstances even if recording begins from "cold start," due to a rise in temperature inside the camera caused by pre-shooting camera setting operations or by prolonged use of the Live View mode. When the card is full, movie recording stops automatically. In this case, duration time when you erase the data and restart shooting.
4K 59.94p (without crop)	40 minutes or longer^{1, 2, 3}
4K 59.94p (crop)	50 minutes or longer^{1, 2, 3}
4K 29.97p (without crop)	Not limited by heat^{1, 2, 3}

Notes

Before recording 4K movies, format cards by selecting [Low level format] in [Set-up: Format card]
If you use a slow-writing card when recording movies, the movie may not be recorded properly. Also, if you play back a movie on a card with a slow reading speed, the movie may not be played back properly.
When recording movies, use high-performance cards with a writing speed sufficiently higher than the bit rate.
Using SD/SDHC cards: The card will be formatted in FAT32. If the file size exceeds 4GB, recording will continue and a new file will be created automatically. FAT32-formatted cards cannot be used when recording movies with a frame rate of 179.8 or 150 fps.
Using SDXC cards: The card will be formatted in exFAT. Even if the file size exceeds 4GB during recording, the movie will be saved as a single file.
An increase of the camera’s internal temperature may cause recording to stop before the maximum recording time is reached.
When movies cannot be recorded properly, format the card and try again. If formatting the card does not resolve the problem, refer to the card manufacturer’s website, etc.
