GoPro Driving Video

This was an experimental 23 minute drive from Borehamewood in Hertfordshire to Edgware in North West London.
Camera was a GoPro Hero 6, the resulting files are huge, around 4GB per 8 minutes. The end video file was just under 12GB, bit rate was 66mbps , I used ffmpeg to drop bitrate to 5mbps which reduced the file size to 900MB. The camera was suspended from a windscreen adaptor, the camera got VERY hot during recording, not just warm but HOT. Still seemed to record OK.
There was some annoying background noise that was not noticeable during the drive, this may be vibration picked up through the camera case.
Had the camera for a few years now but always found the field sizes make using a bit prohibitive, on my older but quad core laptop using ffmpeg to reduce files to a usable size often takes around 5 times the length of video to convert.
Similar drive video done using LIVE CZcams feed, quality quite poor in places.
