Master/Slave Operation

This section includes:

NOTE: Master/Slave operation, including stereo/3D and camera arrays, requires a GIG-E port, which is available on the DSMC2 REDVOLT Expander and DSMC2 Jetpack-SDI Expander. For more information, go to GIG-E (Ethernet).

NOTE: The Master camera controls metadata and basic camera parameters of the Slave cameras. Any other setting changes required by the Slave cameras must be made before recording.

This section describes operation in Master/Slave configuration and clip naming conventions for clips recorded on those cameras. Master/Slave is the most common configuration for Stereo/3D productions.

When cameras are operated in Master/Slave configuration, you can perform the following operations:

  • Power: Turn off the Master camera to turn off both cameras.
  • Record: Press the PWR/REC key on the Master camera to start/stop recording on both cameras.
  • Change settings: Change settings on the Master camera, to change settings on the Slave camera.

For a Master/Slave configuration to function, the cameras must have the same:

  • Firmware version
  • Project time base
  • Recording frame rate
  • BRAIN
  • Sensor

Set Up Master/Slave Operation

NOTE: Master/Slave operation requires a GIG-E port, which is available on the DSMC2 REDVOLT Expander and DSMC2 Jetpack-SDI Expander. For more information, go to GIG-E (Ethernet).

  1. Connect the cameras using the Master/Slave Gig-E Cable:
    1. Connect the GIG-E port on one expander to the GIG-E port on the other expander.
  2. On the Master camera, follow the instructions below:
    1. Go to Menu > Settings > Setup > Communication.
    2. Type a name for the camera (Example: CAM A, LEFT, MASTER, etc) in the Camera ID field.
    3. Set Target to All.
    4. Master Settings

Set Reel Number, Camera ID, and Camera Position

NOTE: Camera ID and Camera Position settings can also be found at Menu > Settings > Project > Slate > Camera.

To prepare media and slate settings for a Master/Slave or Stereo/3D production, follow the instructions below:

  1. On both Master and Slave cameras, go to Menu > Media > Device and select Format Media....
  2. On both Master and Slave cameras, select the desired Reel Number and Camera ID settings. The Reel Number and Camera ID settings on both cameras should match.
  3. On the Master camera, change the Camera Position to Left, representing “left eye”.

  4. On the Slave camera, change the Camera Position to Right, representing “right eye”.
  5. On both cameras, select Format... to format media and set the Reel Number, Camera ID, and Camera Position settings.

Multi-Camera Clip Naming Conventions

This section describes automatic camera-generated clip naming conventions based on slate settings. Cameras use the Reel No, Cam ID, and Cam Pos settings to generate a custom clip name.

For example, if you have two (2) cameras in Master/Slave configuration and format media on both cameras with the following settings:

Camera

Reel Number

Camera ID

Camera Position

Master

1

S

Left

Slave

1

S

Right

The first clip recorded by this Master/Slave camera configuration is:

  • Master: S001_L001_0503B6.R3D
  • Slave: S001_R001_0503R7.R3D

NOTE: B6 and R7 are examples of camera-generated wildcard characters.

NOTE: If both cameras have a Camera Position of Left, the recorded clips will have the same filename structure, with the exception of the camera-generated wildcard characters. For example:

  • Master: A001_C001_0503B6.R3D
  • Slave: A001_C001_0503R7.R3D

NOTE: Reel Number, Camera ID, and Camera Position can be set when formatting media.
