A Queensland man accused of a vicious coward punch attack has walked free after a magistrate refused to watch CCTV evidence of the incident.

Police offered the video as evidence in court yesterday, however Magistrate Rod Madsen rejected it, claiming "I don't like watching videos, they can be very subjective".

"They can become emotive ... I rely on the evidence [and] facts," he said.

The CCTV tendered to the court shows 26-year-old Tyson Wylie jumping a railing and assaulting a complete stranger.

Drunk and enraged at a Sunshine Coast taxi rank, the third punch knocked his victim out cold before he walked away.

Police arrested him just moments later, the incident occurring just six days after Wylie had struck another stranger in Surfers Paradise.

Magistrate Madsen ordered Wylie to pay $5000 in compensation and imposed a 24-month prison term, wholly suspended for three years.
