The film shows Pistorius walking unaided on his stumps, and carrying a woman downstairs, wearing his prostheses.
This footage has not been shown in court, but has been used in a documentary aired on Australia's Channel 7.
Since then, Pistorius's legal team has issued a statement saying that the material aired was obtained illegally and in breach of a non-disclosure agreement.
The court has heard that the athlete was not suffering from a mental condition when he shot Steenkamp, and that he was able to distinguish between the rightful or wrongful nature of his actions.
The trial continues.
