- MP4 - Great compatibility with Camera to Cloud. Will corrupt if the recording is interrupted.
- MKV - OpenSource efficient container.
- MOV - Classic Apple Compatible Container.
- Segmented (Fragmented) MP4 - Creates corruption-resistant MP4 files by dividing them into segments at keyframes. Files can be played back while still recording, enabling real-time preview on upload destinations, local browsers, and NFS drives. Note: Legacy players like VLC may have playback issues, but most modern players support this format.

- On Camera Event - Uses Camera record flags to trigger recording
- On Streaming Event - Uses RTMP based Start / Stop streaming flags to start the recording
-

- Recommended the framerate be set to auto as the input framerate must match the encoding framerate for timecode to match.

-
Loop Recording - Continuously records video and sets the file size to a pre-determined number of minutes.
- Max Size Time - Maximum time allowed per file before creating a new file.
- Max Files - This sets the maximum number of files allowed per cycle before triggering an index rollover, where new files overwrite existing ones with the same name. This is ensures space is saved. 144 files would be 1440 minutes of files.
