I tried searching for this but im in the field right now and on my phone so its a bit difficult.

Does anyone know if its possible to change the duration of the pre record on a p2 370?

It only records ONE SECOND of preroll and as im sure you all know thats barely enough time to get your finger on the record button to salvage the prerolled footage. Im recording in HD.
Does anyone know if I can change this time? I know you can easily on xdcam but I just cant find it anywjere in the menus on a p2. Any help would be appreciated. Thanks!
