a few milliseconds
That's the answer; lightning only lasts a few milliseconds, but your camera takes longer than that to scan the whole image, so in some frames the sky is only half-illuminated.

to a 1,000 times longer (still only a few 10ths of a second)
However, about 5 – 10% of lightning strokes are different; they can last up to a 1,000 times longer (still only a few 10ths of a second), transfer so much electric charge that lightning protection measures are overcome, or they can generate significantly more heat and are far more likely to cause fires or other extreme heat-related damage.

a matter (thousandths of a second of a few tens of milliseconds
The difference in those numbers arises from the fact that a lightning strike only lasts a matter of a few tens of milliseconds (thousandths of a second).
