A raw pre-record buffer option could be extremely useful, specially for documentary work.

For example: pressing the record button once could make the camera continuously record to the buffer, keeping it half-full, but saving nothing to the card. When the record button is pressed again, then the half-full buffer could be saved to the card and the normal recording activated. This way one would always have a few seconds of footage prior to actually starting the recording.

This would allow one to wait for the right moment and start recording a soon as the moment has happened or started happening and not miss anything. Without a prerecord buffer one is often forced to keep the camera recording, wasting tons of memory in the cards, which is specially impractical when working with raw.

could be doable with the API i introduced with bolt_rec.
currently this API is disabled, but will be fixed within the next weeks maybe.
