As just mentioned, clicking New on the icon ring populates the pane at right with related options. Principally, for each session you must designate (by selecting switches) your local video standard (Multi-standard model only – select NTSC, PAL or NTSC-J) and session format –1080i, 1080/24p, 1080/30p, 720p, 720/30p, 720/24p, 480/30i (16:9) or 480/30i (4:3). Multi-standard models offer PAL format equivalents.


You will see a name entry field above the session options in the pane at right. Click in this name field to provide a suitable name using your keyboard.


The Template drop-down menu lists all existing sessions currently available on the system.

If you select one of the entries, the new session will retain all custom settings of the source session, but will not include its CLIP LIST or PLAY LIST media content.


Two optional session modes offer either Redundant (4-channel) recording or Standard (8 Channel) working modes. Generally, hard drives can capture input from two live sources), while keeping up with concurrent playback demands.


In this mode, data for each input channel is mirrored to a second drive, providing failsafe storage and convenient sharing options for your critical footage. This limits capture to four sources (one pair of sources on each pair of drives, as it were).

Tip: The duplicate copies provide redundant data security, and also permit you to offload a complete record of the production for archival or post-production purposes while still having a working session on 3Play (the Session Volume must be mounted in this case).


Standard mode stores just a single copy of your recorded data, freeing up storage volumes to be assigned to more cameras.


Beneath this you will notice a control group labeled Storage Volumes. In this section, you will assign one or more storage devices to be used for replay clips you will record, and other assets associated with the session.

Tip: The titlebar of the Home page has an Eject button to allow you to disconnect and remove storage media.

Suitable hard drives added to a removable drive bay or otherwise connected are listed in the Drives column. 3Play attempts to make an appropriate initial guess at how best to distribute the drives it detects, but you can manually select drives as well.

Note: In Standard (8 Channel) session mode, the Backup column in this area is not used.

Again, it is recommended that no more than two sources be assigned to a single volume in either the Primary or Backup drive assignment columns. If too few drives are mounted, it will not be possible to assign drives to all camera pairs.

Note: In some cases (i.e., very fast volumes) you can sidestep the restriction above (volume labels are orange if more than one input pair is assigned). However, menu rows for inputs are enabled according to the number of drives detected. Even with the world’s fastest, biggest storage volume connected, another qualified drive must be detected before you can configure the second camera pair (3, 4), and so on – even though you don’t plan to use the extra drive(s).

Use the drop-down menus under Inputs to assign drives for recording camera pairs listed in the same row.

Note: External USB drives, while suitable for backup and restoration operations, are not recommended for recording applications. Please see Section B.1.7 regarding suitable hard drives for use in 3Play’s removable drive bays. See also Section 10.2, Storage Volumes.


You could think of the Session Volume as storing all of the ‘non-a/v data’ required by a session, including input settings, metadata, etc. Normally, the actual a/v files will be located on multiple drives, but the Session Volume you choose in this menu can be considered the ‘master’, and must be mounted to open (or re-open) a session.


The format of video output by 3Play varies according to the session type. The session settings also affect capture. For example, if your session format is SD 4:3, this is the format normally captured by the Record function, even when the input Connection Type might be HD to accommodate a specific camera; the converse is also true. The frame is scaled and cropped as required to properly match the session setting, regardless of input type.

Multi-standard 3Play units show the Video Standard option buttons, allowing you to choose NTSC, NTSC-J or PAL for your session, according to your local regional requirements.

The Resolution radio button groups allow you to further configure the recording and output format for the new session.

Note: See Section 7.1 for more information on Video Output configurations.

Having made your selections, you would normally click the Create Session button at lower right (then Create Session to launch the Replay Desktop); but first, let’s explore the features of the Home page a bit more.
