Time Mode
Time mode creates documents that represent a fixed amount of video content. A document contains all of the records that occurred during the time interval, or that overlap the start or end of the interval. You can define the duration of a document, for example 30 seconds. The duration is measured using video time, so you do not need to modify the duration if the ingest rate is slower or faster than normal (playback) speed.
TIP: Time-based output does not mean that Media Server outputs data at regular intervals. Media Server cannot output data for a video segment until all records in that segment have finished. As a result, Media Server might produce several documents, which represent consecutive time periods, at the same time.
For example, if you run logo detection on a news broadcast, the news logo could be present on screen continuously for an hour. In that case, Media Server does not output any data until the logo disappears. Although Media Server creates documents that each represent 30 seconds of content, all of the documents are output at the end of the hour when the record describing the logo finishes.
In time mode, all records are output to at least one document. If a record spans more than one interval it is output to multiple documents.
Time mode is simple to set up but documents might begin and end in the middle of a sentence or segment, rather than at meaningful point in the video.
