Not a black friday deal, but Blackmagic Video assist and AtomOS Ninja Blade Complete are still each $495.

My best BF/CM deals so far have been:
Panasonic GH3 $497 (B&H)

Panasonic DMC-CM1 20 mp smartphone $379 (was $1000 -- B&H)

Canon EOS M3 with Canon electronic viewfinder $447 (B&H)

3DR Solo with gimbal $1099 (B&H)

Go Pro Hero 4 Black $349

Depending on your budget and whether 1080P or 4K is your desired raster, there have been TONS of low-buck options. Just sayin'

Samsung NX1 body $1099
