Larger Chapter Support
GoPro cameras normally split long recordings into 4GB segments, we call these chapters. These 4GB (32-bit) MP4 files are the most compatible, yet larger 64-bit MP4 files are becoming more common. If you have an SD Card that is at least 64GBytes, you can increase your chapter size to 12GB with this control below.

Warning: Larger chapters may not work everywhere in the ecosystem, even the camera will not playback or USB transfer files larger than 4GB in this current firmware. Yet the files are valid and accessible using a SD Card reader, and have been tested to work in many tools. So this one of the more experimental features, so please test before committing to this new workflow. Support for HERO8, HERO9 and MAX cameras.
Known Issue: Larger chapters will not be enabled when using QuikCapture. QuikCapture starts recording before the Labs service starts, resulting in perfectly fine, but only 4GB chapters.
Compatibility: Labs enabled HERO8, HERO9 and MAX
Optional: Joining Chapters After Capture
Whether you are using the larger chapter feature or not, you may still end up with more than one file for very long video captures. Tools like ReelSteady Go can only operate one file at a time, so here is a solution for merging chapters so that they operate as a valid GoPro MP4 of any length, with all the needed metadata.
- install ffmpeg: https://www.ffmpeg.org/
- download udtacopy.zip (source code)
- Unzip and grab the version best for your computer (Mac, Win or Linux) and copy it a folder somewhere (within your executable path).
- Create a text file with a list of GoPro files that need to be concatenated. E.g. filelist.txt
- Start a terminal and run the following commands:
ffmpeg -y -f concat -i your_path_to/filelist.txt -c copy -map 0:0 -map 0:1 -map 0:3 your_output_path/final.mp4
udtacopy your_path_to/the_first_GoPro_file.MP4 your_output_path/final.mp4
The resulting final.mp4 will be a complete GoPro file will all required metadata.
