Bit Depth and Bit Rate Settings in regard to overheating and file size
Bit Depth and Bit Rate Settings in regard to overheating and file size
We found out that the GoPro 13 arrives with the Bit Depth set to 8-Bit HEVC and the Bit Rate set to Standard. Videos under 4k only use 8-Bit, so this only applies to the higher video resolutions, but we were surprised to find out the file size was way smaller, and the camera didn’t overheat as soon.
Recording at 4k 30fps in direct sunlight, 105˚F, the GoPro 13 lasted 52 minutes before overheating. The camera was configured with Bit Depth 8-Bit HEVC and Standard on the Bit Rate with a file size of 15.37 GB.
Set to Bit-Depth 10-Bit and High Bit-Rate, the camera overheat occurred at 28 minutes with a file size of 17.87 GB.
For additional reference the other cameras overheated as follows.

HERO 2024: 32:16
Action 4: 24:53
No camera overheating occurred when our coolers were used on October 10/10/2024 at 105˚F in direct sunlight at 4K 30fps. All cameras recorded for over 4 hours during the hottest part of the day in direct sunlight.
However, it’s essential to note that while all action cameras struggle with heat management, the choice of settings can significantly affect performance and recording time. Users looking to maximize their recording duration in high-temperature environments may want to stick with the 8-Bit HEVC and Standard Bit Rate settings to avoid overheating or add an extra margin. Additionally, as the temperature increases, recording resolutions may need to be lowered significantly to prevent camera overheating.
The GoPro 13 with high resolutions and frame rates showcases its capability, but it also highlights the importance of understanding the trade-offs involved. Higher bit depths, bit rates, and resolutions can enhance video quality, particularly in scenes with a lot of detail or rapid motion, but they also generate more heat and larger file sizes, which can limit recording times. 10-Bit video, which produces over 1 billion colors compared to the 16 million colors of 8-bit. This is extremely advantageous for those that want to post-process their videos, but for normal users 8-Bit is probably sufficient for most scenarios.
For those who prioritize longer recording sessions over ultimate video quality, some video is better than no video. Utilizing our cooler fan is a smart choice as it allows users to take full advantage of the camera’s capabilities and reduces the chances of overheating, especially during outdoor shoots in challenging conditions.
