Configuring recording settings

You may customize a variety of the recording settings for the IP VCR to most closely fit your needs. To view and change the recording settings, choose Settings > Recording. When you have finished editing any of the fields, click Apply changes to make them take effect. Refer to the table below for a description of the different fields:

Recording settings

Field Field description Usage tips
Loop when playing back recordings via H.323/SIP

Check this option if you wish recordings to automatically return to the start and continue playing when the end is reached during playback.

Even if this field is set, recordings will not loop while fast-forwarding.

This setting applies only to playback by H.323 or SIP and not to streaming

Always send video to participants being recorded

If this option is checked, the IP VCR will always send video to any participants being recorded. If the recording console is not in use, the video sent to the remote system will be blank.

When recording a conference on a remote MCU, if the IP VCR sends video to the far end as well as recording the video it receives, it may be the case that the video sent by the IP VCR ends up as part of the recorded conference in addition to the "real" participants in that conference.

In theory, the IP VCR should not need to send video to an endpoint or MCU device that it is recording. However, some devices are programmed not to transmit video unless video is sent to them, and so this option allows the IP VCR to work with such systems.

Use date and time in new recording names

Check this option to have the date and time included in the names of new recordings.

Recording names are either entered by a user or automatically generated by the IP VCR. This option applies to names that the IP VCR has generated. Note that the IP VCR generates recording names from the name supplied by the recorded endpoint.

New recordings inherit folder's PIN

Check this option to have new recordings' PINs set to the same value as the PIN of the folder in which they are initially stored.

With this option unchecked, even if a folder has a PIN, any new recordings made into that folder will not automatically be assigned a PIN.

With this option checked, users navigating to this folder via the Streaming-only interface or the auto-attendant will have to enter the PIN once to view the contents of the folder and again to watch a recording. However, with this option checked, users directly accessing recordings in this folder will only have to remember one PIN.

Point to point layout

Choose one of these layouts for making point-to-point recordings:

  • Side-by-side
    side by side layout
  • Loudest speaker with small picture-in-picture
    small picture in picture layout
  • Loudest speaker with large picture-in-picture
    large picture in picture layout

Picture-in-picture views display the currently loudest speaker in a full-screen view, with the other displayed reduced in size in one corner. The speakers will exchange places depending on who is speaking.

Multicast transmit IP address range

Use these fields to specify the range of multicast addresses to which the IP VCR may send multicast media for streaming.

If these values are not configured, the IP VCR will be unable to stream recordings using multicast media.

Multicast addresses are in the range 224.0.0.0 to 239.255.255.255 inclusive.

Multicast transmit port number range

Sets the range of port numbers to which multicast media will be sent.

This UDP port number range is used in conjunction with the Multicast transmit IP address range.

You must set both the start and end port numbers to transmit recordings by multicast streaming.

Players allowed

Sets the media players that can be used for watching recordings.

This is a unit-wide setting that affects the options available to a user selecting to watch a recording.

Streaming protocol for Windows Media Player

Sets the protocol that Windows Media Player will use.

The default protocol for Windows Media Player is HTTP and v11 no longer supports MMS over UDP or MMS over TCP.

Media settings

Field Field description Usage tips
Native media
HD video capture mode

Enables the IP VCR to record video at up to HD quality. If you leave this option unselected, the IP VCR will record the video at up to SD quality only.

Only enable this mode if you want to make HD recordings.

When HD video capture mode is on, live streaming is automatically disabled. This is because HD video recordings cannot be live streamed on the IP VCR; HD recordings must be transcoded before they can be streamed.

Note that this setting takes effect when a recording is started. If you change this setting, recordings in progress will use the setting with which they started. You can temporarily enable this mode for individual recordings if required.

HD recordings cannot be played back on a video endpoint. You can, however, choose either to have all recordings transcoded to streaming media by checking Store streaming media (below) or to transcode individual recordings to streaming media (refer to Viewing and updating recording details).

Any SD recordings made while HD video capture mode is on, can be played back on a video endpoint.

Streaming media
Allow live streaming

Enables live streaming on the IP VCR.

Live streaming is the streaming of video that is currently being recorded.

Note that live streaming is disabled if you have allowed the recording of HD video (see above).

When live streaming is enabled, the IP VCR simultaneously records and transcodes to streaming media. However, the IP VCR will not store the transcoded media for streaming after the recording is complete; select Store streaming media if you require the streaming media to be stored.

Store streaming media

This option controls the transcoding of new recordings to streaming media. It configures the IP VCR to transcode and store every new recording for streaming.

With this option selected, new recordings are transcoded to streaming format.

Recordings that start when HD video capture mode is selected are transcoded when the recording is complete. Streaming can take place when the transcoding is complete. Live streaming cannot be used with these recordings.

Recordings made when HD video capture mode is not selected are simultaneously transcoded. Streaming can take place as soon as the recording is complete. Live streaming can be used with these recordings if you select Allow live streaming.

Streaming media takes up extra space on the IP VCR. You might disable the creation of streaming formatted recordings if space has become short on the IP VCR. Note that where space has become short you might want to consider Storing recordings externally.

Note that for every recording, on the recording's details page, there is a button that allows you to transcode the recording for streaming. There is also a button that deletes the streaming media for that recording.

Streaming recording video bit rate 1

When making recordings, as well as storing the incoming media packets as they are received, the IP VCR also re-encodes the media (using two different video bit rates) in a form suitable for streaming to users' desktop machines (see Using streaming to view recordings).

These settings control which bit rates are used for the streaming video – typical usage would be to configure one low value suitable for users connecting over a low bandwidth link, and a higher value to give better quality to users with a faster network connection to the IP VCR.

Check the Multicast option next to one or both of the streaming recording settings to enable multicast streaming of "live" recordings (i.e. those in the process of being made). Note that you cannot use Windows Media Player to stream a conference in multicast mode.

In addition to the video bit rates specified, streaming media includes an additional 64kbit/s audio stream; the total media rate, in bits per second, when streaming will thus be one of the specified video bit rates plus 64000.

Streaming recording video bit rate 2
Content channel recording bit rate

When recording H.239 (content channel) video from H.323 video conferencing devices, the IP VCR re-encodes the H.239 stream to a form that can be served to users' desktop machines. This setting determines the bit rate of the recorded content channel streaming video.

This bit rate controls the rate at which content channel streaming video is recorded. Once a recording has been made, all later streaming of the content channel video will use the bit rate set at record time, so this value should not be so high as to exceed the available bandwidth between the IP VCR and potential streaming viewers.

Media export
Allow MPEG1 export

Enables the downloading of recordings in MPEG1 format.

This option controls whether or not the "download MPEG file" link appears on a recording's details page.

MPEG1 export video bit rate

The IP VCR records raw media packets from H.323 video conferencing endpoints. It also provides the facility to export recordings in MPEG format (typically for download and playback on a PC), and this setting controls the video bit rate of such exported files.

MPEG1 system stream files generated by the IP VCR comprise video plus 64kbit/s audio, and so the total media bit rate will be the specified video bit rate plus 64000.

A higher bit rate will give better quality, at the expense of generating larger download files; higher bit rate files will also take longer to be produced.
