targetIntervalSeconds

The targeted thumbnail-generation interval in seconds. This is configurable (and required) only if recordingMode is INTERVAL. Default: 60.

Important: For the BASIC channel type, setting a value for targetIntervalSeconds does not guarantee that thumbnails are generated at the specified interval. For thumbnails to be generated at the targetIntervalSeconds interval, the IDR/Keyframe value for the input video must be less than the targetIntervalSeconds value. See Amazon IVS Streaming Configuration for information on setting IDR/Keyframe to the recommended value in video-encoder settings.
