He said the videos had always been at the centre of the case, and police should have evaluated their evidence better before pressing sexual violation charges.
During the trial Mr Keegan and Ms Hughes criticised police for not questioning the complainant more thoroughly, to find inconsistencies in her side of the story.
They pointed to a number of incidents that indicated she may not have been as intoxicated as she claimed.
Mr Keegan said his client had been through 13 months of hell, since the charges were laid.
"Obviously as teenagers, going through a rape prosecution of this nature has been extremely stressful."
Detective Senior Sergeant Blair Burnett wouldn't comment on Mr Keegan's criticisms, but said there were no winners in the situation.
"I admire the courage of the complainant, and I would encourage any other people to come forward if they were faced with the same situation."
Mr Keegan said the eight-day trial was a reminder of how easily things can get out of hand on social media.
"Young people need social media training.
"Be very careful what you're doing, what you're posting, what you're filming, and what you do with that."
The judge will deal with applications for name suppression on December 19.
He will also consider Ms Hughes' application for her client to have his conviction for making an intimate visual recording discharged.
