The following table describes the parameters of a recording template.
Parameter
Description

Recording Cycle
The recording cycle can range from 15 to 360 minutes. If the specified recording cycle is exceeded, the system generates a new recording file based on the recording naming rule. By default, the length of a TS segment is 30 seconds.
NoteThe recording cycle specifies the maximum length of a VOD file that is converted from the specified live stream.
Transcoding Settings
Select a storage transcoding rule from the drop-down list. You can transcode the recorded videos in ApsaraVideo VOD.
The storage transcoding rule is used to convert the recorded videos to VOD files for transmission. You can transcode the recorded videos to videos of different resolutions or retain the original quality without transcoding.
For more information about transcoding templates, see Configure transcoding template groups.
NoteThe region of the transcoding template that you use in ApsaraVideo VOD must be the same as the region of your domain name. For example, if your domain name resides in the China (Shanghai) region, the transcoding template that you use in ApsaraVideo VOD must also reside in the China (Shanghai) region.
Click OK.
Disable the recording feature
If you do not need to use the recording feature, you can delete the added recording templates to disable the feature.
If live streaming is in progress when you delete a template, ApsaraVideo Live continues to record based on the template. The deletion takes effect for subsequent ingested streams.
