Loop Recording has been fairly intuitive to setup up until the GoPro HERO 7. The option is still available on the HERO 8, but it wasn’t obvious to me how to enable it. Now that I’ve found out how to do it, I thought I’d share it with you.
The trick is that any of the new settings presets (i.e. Standard, Cinematic and Activity) cannot enable Loop Recording. You have to create a fourth (custom) preset with which you can activate it.
