[Loop Recording (Video)] - Panasonic LUMIX DC-GH6 Owner's Manual

Special Video Recording – [Loop Recording (video)]

[Loop Recording (video)]

Recording continues until the card becomes full, while dividing videos into
short periods.
When the card becomes full, recording continues while deleting the old
data.
This is a convenient function for recording over long periods that might
exceed the capacity of the card.
•
Recording and deleting occur at the same time, so you will need a card with a
writing speed equivalent to double the bit rate of the recording quality used for
recording.
If the writing speed on the card is insufficient, recording may stop.
