The initial Reports often contain erroneous information and during the course of the Accident Investigation you shall no doubt be able to provide your account of the event to the Investigators.
Be professional in your relating your account and just tell the Investigator what you know, what your perceptions of how it all played out and don't worry much about the preliminary reporting.
If you have a video of the event that shall speak for itself I would assume.
When the Investigator asks you a question just respond in a factual straight forward manner and simply tell the truth....whatever it is.
You were the Student under the supervision of your Instructor and it is he that is reaponsible for the aircraft and its occupants.
