What is the new pre-recording feature of the Zenmuse H30 Series? What is it for?

Pre-recording is a feature that allows the device to cache a segment of video for a set duration before the user starts recording. When recording begins, the cached content is included in the video, preventing excessive use of microSD card space. Purpose: With pre-recording enabled, even if recording starts after an event has begun, the device can save the moments before the recording started onto the microSD card, ensuring that potentially critical information isn't missed.
