The 30 day limit is set by default as a built-in safeguard against having a longer recording that results in an extremely large manifest that needs to be loaded into memory and will likely cause issues in a real world deployment. There are serious drawbacks to having such long recordings which is why we have set this limit. See [recording length best practices](https://www.wowza.com/docs/wowza-ndvr-quick-start-guide#recordingLength).

You can extend the maximum recording time value by adding this property dvrMaximumRecordingLength to the /DVR/Properties section of Application.xml. The default is set to 108000 (30 hours). However, we strongly advise against increasing the recording length and playing back such a long recording.

```auto
<Properties>
     <Property>
          <Name>dvrMaximumRecordingLength</Name>
          <Value>108000</Value>
          <Type>Integer</Type>
     </Property>
</Properties>

```

nDVR is also interesting for the ability to perform live2vod task. @Lisa Wong is there still a limitation?

There is no way to set nDVR length for playback? Which then could be different from archive?

Usually there is 2 different length for nDVR: window (available in players) and archive (well, for archiving).

Thank you.
