I was trying to film dogs catching Frizbee the other day, and was thinking, I wonder if there's a way to add a buffer record to Raw_Rec module, like have it record to buffer but not to file for the certain amount of frames the user chooses as a buffer, then when the action you want happens, you press the shutter and it records the buffer to video file?

it's often called "Pre-Trigger" "loop recoding" after you press the shutter it will save let say 5sec before the event + 5sec after.
It can have pre-trigger and post-trigger, some cameras call it loop recording too. (mostly loop recording it' means after the memory is at the end it will start from the start again.
