Although the duplicator will attempt to keep the file system on each card organized and
prepared in case a card is removed during recording, it's important you don't remove an
SD card while your Blackmagic Duplicator 4K is recording. This is because some operating
systems that could be used to view the card are not as robust as others and they might see the
recording as being damaged. So it's always safer to stop recording before removing a card.
If you do find that you want to be able to pass cards to people before a performance has
completed, it might be a good idea to use multiple duplicators and then you can stop one unit
early to distribute cards from that unit, while the other units keep recording.
TIP
supported by your Blackmagic Duplicator 4K, you can also record lower data rates
using cards with a slower rating if you need to. For example, you may wish to record
security vision for long durations and don't need the highest video quality. We
recommend always performing a test recording to make sure your SD card can record
video at your chosen bit rate. For more information about SD card speed ratings, refer
to 'inserting and formatting SD cards' in the Getting Started section.
Append Record
When recording in duplicate mode, you may wish to record a new clip, and add it to the
previously recorded clip so they appear as one single clip. For example, you may be recording
a performance with multiple separate events. If you want to record each event separately, but
have them combined into one clip, this is how the 'append record' feature can help you.

clips you can append to the first clip. The only consideration is the size of the card and
length of the recordings.

Record the first clip as you normally would using the 'record' button. Press stop.
When the next event starts, press the 'append record' button. The button will be
illuminated together with the standard 'record' button to let you know you are recording
a clip that will be appended to the previously recorded clip.
Press stop. The new clip will then be appended to the first clip and they will be saved
as one single clip.
