The former students at the University of Free State pleaded guilty to crimen injuria at the trial on Tuesday.
The video showed the five staff being made to kneel and forced to eat food which had apparently been urinated on by one of the students.
The video sparked anti-racist protests when it surfaced in 2008.
The trial was seen as deeply symbolic in a country trying to come to grips with its racially divided past, 16 years after the end of white minority rule.
The four - RC Malherbe, Johnny Roberts, Schalk van der Merwe and Danie Grobler - were also given six-month prison terms, suspended for five years on condition they are not found guilty of discrimination during that period.
The fines of 20,000 rand were higher than that requested by the prosecution.
"It sends a strong message to potential offenders of similar crimes," said magistrate Mziwonke Hinxa in the mainly white town of Bloemfontein.(click here to read the entire BBC News Africa story)
