The Leica SL3 has no video recording limit for all formats. However, that limit is dependent upon multiple factors like camera settings, media storage size, camera power, and internal camera temperature. See details and notes below for more information.

Notes
The maximum file size for an uninterrupted video recording is 96GB. Once a recording exceeds 96GB, the overrun will be automatically stored in a new file.
An increase of the camera’s internal temperature may cause recording to stop before the maximum recording time is reached.
