The node saves a snapshot in
jpg format, along with the Pipeline metadata contained in that frame, as a files API object.
Files created by this node are also listed in the Console under the Deployment detail page.
This node creates 2 files for every snapshot it saves:
Media file (JPEG format), named
snapshot1-2023-01-20T083909.952Z.jpg. The timestamp in the file name is the creation timestamp. This file contains the media for the snapshot in jpg format.
Metadata file (JSON format) named
snapshot-2023-01-20T083909.952Z.jpg.json. This file contains the metadata for the frame contained in the media file in JSON format.

lumeo_cloud snapshots are temporarily stored at
/var/lib/lumeo/clip_upload (till they are uploaded).
|Maximum number of files to keep on local disk, when
local, for this specific node. Ignored when
If this property is not set, Lumeo will continue to save till the disk fills up. If it is set, Lumeo will save to local disk in a round robin manner (overwrite the 1st file once
max_edge_files have been written).
|Save a snapshot when this condition is met, subject to Trigger mode property below.
The trigger expression must be a valid Dot-notation expression that operates on Pipeline Metadata and evaluates to
False. See details here.

Single : Take a snapshot once every time the trigger condition is met (goes from False to True).
Exact : Take a snapshot of every frame for as long as the condition is met.
