Car drives normal, clouds are 52 times faster.

I had my ND Fader near max for the timelapse at low ISO at 1/2s.

For second video the Fader was min and higher ISO with usual 1/50s.

Both videos were recorded at 25p whereas for timelapse every 13st Frame was used and blended 4 times == 4x13 == 52 times faster.
