+            
+            These are the available statuses:
+            
+            `missing`: the input for a summary is not present.
+            `waiting` : the input video is being processed and a summary will be generated.
+            `failed`: a technical issue prevented summary generation.
+            `completed`: the summary is generated.
+            `unprocessable`: the API rules the source video to be unsuitable for summary generation. An example for this is an input video that has no audio.
