Blackmagic Duplicator 4K is two recorders in one. Equipped with 25 slots, it records simultaneously to all inserted SD cards, or to one card at a time for longer recordings. In duplication mode, you get up to 25 copies in H.264 and H.265 ready for distribution at the end of the event. Sales opportunities are plentiful, e.g. to fans after a concert, to participants at a conference, or to parents at the end of a school play. In sequential recording mode, Blackmagic Duplicator 4K performs long duration recordings on one SD card at a time, down to the last. With 25 cards, you can record for weeks at a time without having to replace them. In overwriting mode, however, recording continues indefinitely, overwriting previously filled cards, an ideal mode for video surveillance and live programme archiving.
