Recording long videos

When recording longer videos using GoPro cameras, battery life can quickly deplete. However, GoPro cameras (Hero 8 Black onwards) can be charged while recording. To extend the battery life for temporary installations, USB battery banks can be mounted with the camera, or for permanent installations, we recommend wiring into the vehicle�s electricity supply.

For the Hero 7 Black and older which use an external mounting frame, this will require charging door removal. Below is a video walk through.

Storage Capacity

Another common problem with recording longer videos is the file size. Unless 4K and/or 60FPS is specifically required, we recommend recording at 1080p (Full-HD, 1920x1080) at 30FPS (frames per second). This keeps the file size manageable for long recordings, compared to 4K or 60FPS videos, which would consume significantly more storage per second of video.

1080p @ 30FPS = 30Mbit/s (3.75 Mbytes/s).

This equates to 17 minutes of video per 4GB chapter.

64GB	8 hours
128GB	16 hours

Storage Media Recommendations

Ensure you use a microSD card from a trusted brand (e.g. SanDisk, Lexar or Samsung) to minimise the chance of corrupted or lost data, or the camera freezing up. GoPro maintains an up-to-date list of recommended storage cards, found here.

Model	Maximum Storage Capacity
Hero 10 Black and newer	1TB
Hero 9 Black and older	Up to 512GB

microSD Card Storage Capacity	Format As�
32GB and below	FAT32
64GB and above	exFAT

Camera Temperature Regulation

Our testing showed that GoPro cameras run relatively hot when recording continuously.

When mounting the camera inside a vehicle, aim to keep the camera out of direct sunlight.

Alternatively, mounting the camera outside of the vehicle will create enough airflow when driving to keep the camera cool. This will reduce the likelihood of the camera becoming unresponsive or shutting down due to overheating.

Post-Processing the Data

Before loading the files into Analysis, it is recommended to join the video chapter files into a single video file using the Race Technology Video Joiner, supplied with both the Race Technology Full V10 and GoPro-Only software packages, which keeps the GPS data intact. The RT Video Joiner software can handle both MP4s and LRVs.

Before joining videos, use the video preview window to establish any unwanted chapters and delete these chapters in a File Explorer window. Ensure that you then refresh the Video Joiner file tree once these files have been deleted.
