Outputting Tracking Data

This function outputs tracking information, using the free-d D1 protocol and OpenTrackIO protocol, synchronized to the sync signal.

The main output data content for each protocol is given below.

Protocol Main output data
free-d D1
  • Lens information (lens encoder, iris)
  • Camera position and orientation information
OpenTrackIO
  • Lens information (lens encoder, focal length, entrance pupil position, subject distance, iris)
  • Camera position and orientation information
  • Camera information (ISO sensitivity, shutter angle, filmback size, frame rate)
  • Timing information (timecode)

The unit is OpenTrackIO v1.0.1 compliant.

  1. Access the Web App.
  2. Set the tracking data output method.

    The settings vary depending on the output protocol (free-d D1 / OpenTrackIO) and transfer method (unicast / multicast).

    Unicast output of tracking data using the free-d D1 protocol

    1. Configure the following items for [Technical] > [Tracking Data Output] > [Unicast Destinations] > [1] to [4] in the web menu.
      Item Description
      IPv4 Address Specify the output destination IP address.
      Port Specify the output destination port number.
      Protocol Specify the “free-d D1” protocol.
      Output Set tracking data output to “On.”
    2. Configure the following item for [Technical] > [Tracking Data] > [free-d D1].
      Item Description
      Camera ID Specify the ID of the unit.

    Unicast output of tracking data using the OpenTrackIO protocol

    1. Configure the following items for [Technical] > [Tracking Data Output] > [Unicast Destinations] > [1] to [4] in the web menu.
      Item Description
      IPv4 Address Specify the output destination IP address.
      Port Specify the output destination port number.
      Protocol Specify the “OpenTrackIO” protocol.
      Encoding Specify the encoding format.
      Output Set tracking data output to “On.”
    2. Configure the following item for [Multicast Destination].
      Item Description
      Source Number (OpenTrackIO) Specify the source number.

    Multicast output of tracking data using the free-d D1 protocol

    1. Configure the following items for [Technical] > [Tracking Data Output] > [Multicast Destination] in the web menu.
      Item Description
      IPv4 Address Specify the output destination IP address.
      Port Specify the output destination port number.
      Protocol Specify the “free-d D1” protocol.
      Output Set tracking data output to “On.”
      TTL Specify the TTL value.
    2. Configure the following item for [Technical] > [Tracking Data] > [free-d D1].
      Item Description
      Camera ID Specify the ID of the unit.

    Multicast output of tracking data using the OpenTrackIO protocol

    1. Configure the following items for [Technical] > [Tracking Data Output] > [Multicast Destination] in the web menu.
      Item Description
      IPv4 Address Specify the output destination IP address.
      Port Specify the output destination port number.
      Protocol Specify the “OpenTrackIO” protocol.
      Encoding Specify the encoding format.
      Output Set tracking data output to “On.”
      Source Number (OpenTrackIO) Specify the source number.
      TTL Specify the TTL value.

Hint

  • Tracking data output destinations can be configured using IPv4 only.

Data output format

Hint

  • Technical details are provided in the “Integration Manual for Tracking Data Output.” Contact a Sony sales representative.

The tracking data that is output by the unit comprises the data according to the format specified in Type D1 of the free-d protocol or according to the OpenTrackIO protocol format.

When the OpenTrackIO protocol is specified, data is stored and output in either JSON format (text-based data description format) or CBOR format (binary-based data description format) as the encoding format.

Note

  • Tracking data may be delayed or values may not be updated in the following situations:

    • When S&Q Motion is on
    • When displaying the camera menu
    • When displaying the thumbnail screen
    • When playing recorded clips
    • When displaying the web menu
  • Set [Output] to [Off] for destinations to which tracking data does not need to be sent.
  • Transmission occurs in the order [Unicast Destinations] [1], [2], [3], [4], and then [Multicast Destination]. When sending to multiple destinations, the latency will be greater for subsequent destinations (the latency may increase depending on the network environment).
  • The camera offset information handling is different in version 4.00 and later.
