But Justice Graham Lang said the offending implied Patel was trying get other people to join him in showing support for the terrorist group.
He also found while the original sentence may have had a high starting point, Patels' previous convictions for threatening to kill and assault with a weapon in 2014 and 2015 called for a harsher sentence.
"The latter charge is particularly concerning because it involved Mr Patel holding a large knife to the throat of another person whilst yelling an Islamic remark," Justice said, adding it was during a "road rage" accident.
According to police, Patel sent texts to 52 people in October 2015 containing links to websites showing violent videos and was caught with 62 videos on DVDs, USBs and a laptop and an iPod.
In one video, 14 men in military uniform, possibly Iraqi soldiers, knelt in a row with their hands behind their backs while two men proceeded down the row shooting the victims in the back of their heads.
Another video showed a man in an orange jumpsuit being beheaded in a desert by a masked man, after which another man was led out and shot.
