Administrators and content owners can create multiple versions of a recording or live stream by using recording key settings. They can also add versions of the recording by clicking Manage video formats on the video’s Edit properties page. New versions are created from the original video as server resources become available.
| Option | Description |
|---|---|
| Low bit rate version | Generates a second dual stream video version at the bit rate specified for Internet PC viewers whose bandwidth cannot support the primary video’s bit rate. The server automatically determines which version to send to PC viewers based on the quality of their Internet connection. |
| Mobile stream 1 | Generates combined main and presentation video for mobile devices at the bit rate specified. Set this to the highest bit rate the device can sustain with a good Internet connection. |
| Mobile stream 2 | Generates a second combined main and presentation video for mobile devices at the bit rate specified. Set this to the lowest rate to ensure mobile devices with slower Internet connections can experience uninterrupted streaming. The client automatically determines which version to use based on the network connection. |
| Mobile stream layout | Appears only when a mobile stream is enabled. Specify the layout of the combined main and presentation video in the stream. The viewer cannot change the layout. |
NOTE: Creating low bit rate or mobile streams uses additional storage and reduces capacity for simultaneous recordings.
Mobile streams use the industry standard Apple HTTP Live Streaming protocol, which supports live and recorded streams, and streams at different bit rates.
Click Add selected formats to schedule the transcoding of the new versions. The page updates to show the versions of the video, their resolution, bit rate, type, disk usage and whether they are available or pending creation. You can delete rarely used or otherwise unwanted versions at any time from this page.
