Yes, the K2 will still record in 15 min clips when you have turned off the loop recording.
Disabling loop recording only means, that the K2 will not delete older videos when the sd card got full. The clip length in this mode is fixed at 15 min.
I guess they chose 15 min as a compromise between the number of clips and a manageable file size.
Frostie, so if I disable loop recording, once the card is full it will NEVER overwrite the old files??? I have to go in an erase files to make more room??? based on my calculations/settings a 15min clip utilizes 2,707,308 KB (1,353,654KB per camera)...so my 256GB card can store approximately ninetyfour 15min recordings(front and back) or about 23hrs....So I have to go and delete after 24hrs of active riding...but if I keep it on the longest available setting of 10min loop, it will overwrite once full???.
That is exactly how it works.
