We already knew that the new Canon EOS R5 is limited by overheating in its 8K video mode. However, Canon has confirmed that overheating also affects the recording durations when filming 4K video – all the way down to 4K 30p. 

The manufacturer was very up-front about the overheating limits in 8K video, and we know that the Canon EOS R5 will record about 20 minutes of 8K before it needs to shut down.
