During an intimate act, the man made a seven-second video and a 10-second video on his phone which he then later uploaded to a Facebook messenger group chat with eight others.
But within a week, the man realised the gravity of what he'd done, deleted the video and asked his friends to delete it too.
Judge Grant Fraser read from a statement from the victim who said she'd developed insomnia and flashbacks to the night of the recordings.
She would also suffer a psychological impact "probably for the rest of her life" from the serious offending, Judge Fraser said.
"There can be no doubt that this has had a huge impact on her."
However, the impact of a conviction and publication of his name would have a greater consequence than the weight of the charges, Judge Fraser said.
The teenager's ability to travel freely would be "a significant inconvenience" and a conviction would also affect future job prospects as he had been offered semi-professional sporting contracts overseas.
The teenager also had an "exemplary record" in both the academic and sporting worlds, showed significant remorse and Judge Fraser accepted the behaviour was out of character.
Judge Fraser discharged the man without conviction in return for a guilty plea and a $2000 reparation payment to the victim. The sentence was handed down this morning after the payment was made.
