Considering the responses I had to my previous post about viewing downloaded videos in the Blackvue PC Viewer, I tried to reformat my microSD cards and reset the firmware to record in H.264 codec. The microSD card I removed from the dashcam allowed me to access the firmware settings, but a spare (in fact, the original Blackvue microSD card that shipped with the dashcam) did not have the firmware tab visible. I reformatted the second card to erase the old H.265-encoded recordings, but now I'm wondering what codec and sttings will be used when I insert that microSD card into the dashcam. Does the dashcam retain the firmware settings from the last microSD card? I have a DR900S-2CH.
I have another spare microSD card on order--scheduled to arrive today, in fact--and I'm wondering if the firmware tab will not show when I try to format it for use.
