The difference is numbering of the pin.
But important is that the mic line has polarity.
SJCAM improved power system at SJ8.
When using SJ7 with mobile battery, becomes empty & SJ7 shut down even if inner battery is full.
At the case...
Dear Sulev. I tried dry cell battery, but the noise appeared.
Type C to RCA Cable for YI 4K+ can be use as SJ8 Video Out Cable.
･Must enter FPV mode, and exit before power off
My old M20 can record without time limit setting, but not yet try.
If there is no limit setting, file is cut every 4GB and drop out occurs.
I always use "avidemux" to connect files, and there is no gap.
Where is your YT video?
every 10 seconds or minutes?
You use iRig Mic Lav, do you need to monitor mic sound ?
SJ6 do not have audio out, so you can not monitor.
