By default, MDC10W records video in clusters of 1 minute. It can also be set to 3 minutes or 5 minutes. Although a longer loop recording time improves continuous playback, it will result in larger files, which is more difficult to manage. To change the default duration for each recording cluster, tap in Hubble Dashcam app, select Dashcam settings > Loop recording. Once your SD card is full, it will automatically overwrite the oldest footage.
