A hybrid camera called the Canon EOS R5 can record video at extremely high bitrates. When you select the highest 8K RAW video quality option, 2,600Mbps are saved. 100 frames per second in 4K results in a bitrate of 1,880 Mbps, 50 frames per second in 940 Mbps, and 1,000 frames per second in 10-bit Canon log. Moving all that data around causes internal components to become busy, and active internal components cause heat.
Why does the Canon R5 overheat?
The R5 was able to detect its own overheating and shut down protectively, but as internet sleuths quickly discovered, dramatic changes in the ambient temperature didn’t make a significant difference in how long it took for the camera to overheat. This suggests the R5’s overheat protection was the work of a timer rather than a thermometer. Bring on the internet meltdown and a flurry of hot reactions, which is ironic.
Depending on the type of work you do, the R5’s overheating issues may or may not be a concern for you. There are a ton of factors that will affect it. The majority of the overheating problems are caused by prolonged, nonstop recording times in the 8K RAW recording mode and the 4K HQ recording mode.
