Indicates the format in which thumbnails are recorded. SEQUENTIAL records all generated thumbnails in a serial manner, to the media/thumbnails/(width)x(height) directory, where (width) and (height) are the width and height of the thumbnail. LATEST saves the latest thumbnail in media/latest_thumbnail/(width)x(height)/thumb.jpg and overwrites it at the interval specified by targetIntervalSeconds. You can enable both SEQUENTIAL and LATEST. Default: SEQUENTIAL.

The targeted thumbnail-generation interval in seconds. Default: 60.
