What is “circular buffer” or “loop” recording?
Each slo-mo Phantom camera comes with a fixed amount of very high-speed dynamic RAM. When the camera is in the pre-trigger mode (you’ve pressed “Capture” in the user interface), the camera is continuously recording images into that memory. When it gets to the end of memory, it cycles back to the beginning and continues recording. This behavior is called “circular buffer recording”. The slow motion camera is always “live”. What you end up actually saving in memory is a function of how you’ve set up your trigger. You can set it up such that only frames that occur after the trigger are saved, so any images already in memory are overwritten and you record an event after the trigger (until memory is full). If you set the trigger to stop the recording and save all frames up to the time of the trigger, the camera will simply stop recording upon the trigger and all the frames in memory before the trigger will be saved. Finally, you can set the trigger anywhere in the middle, for example having
