Main Page → Motive Documentation → Synchronization → Properties: eSync
By modifying the device properties of the eSync, users can customize the sync configurations of the camera system for implementing various sync chain setups.
While the eSync is selected under the Devices pane, use the Properties pane to monitor the eSync properties. Here, users can configure the master sync source of the camera system and also the output sync signals from the eSync for integrating slave devices (e.g. NI-DAQ). For a specific explanation on steps for synchronizing external devices, read through the following page: External Device Sync: eSync.
Configure the input signal by first defining which input source to use. Available input sources include Internal Free Run, Internal Clock, SMPTE Timecode In, Video Gen Lock, Inputs (input ports), Isolated, VESA Stereo In, and Reserved. Respective input configurations appear on the pane when a source is selected. For each selected input source, the signal characteristics can be modified.
Clock Freq (Hz): Controls the frequency of the eSync's internal sync generator when using the internal clock.
Sync Offset (us): Introduces an offset delay, in microsecond, to selected trigger signal.
Input Trigger: Sets the trigger mode. Available modes are Either Edge, Rising Edge, and Falling Edge, and each of them uses the corresponding characteristic of the input signal as a trigger.
Input Divider: Allows a triggering rate, compatible with the camera frame rate, to be derived from higher frequency input signals.
Input Multiplier: Allows a triggering rate, compatible with the camera frame rate, to be derived from lower frequency input signals. Available multiplier range: 1 to 15.
Final Frame Rate: Displays the final rate of the camera system.
eSync 1 ports
Allows you to configure signal type and polarity of synchronization signal through the output ports, including the VESA stereo output port, on the eSync.
Type: Defines the output signal type of the eSync. Use this to sync external devices to the eSync.
Polarity: Change the polarity of the signal to normal or inverted. Normal signals constantly output a low signal and pulses high when triggering. Inverted signals constantly output a high signal and pulse low when triggering.
Trigger Source: Determines which trigger source is used to initiate the recording in Motive. Available options are Software, Isolated, and Inputs. When the trigger source set to software, recording is initiated in Motive.
With the eSync, external triggering devices (e.g. remote start/stop button) can integrate into the camera system and set to trigger the recording start and stop events in Motive. Such devices will connect to input ports of the eSync and configured under the Record Triggering section of the eSync properties.
By default, the remote trigger source is set to Software, which is the record start/stop button click events in Motive. Set the trigger source to the corresponding input port and select an appropriate trigger edge when an external trigger source (Trigger Source → isolated or input) is used. Available trigger options include Rising Edge, Falling Edge, High Gated, or Low Gated. The appropriate trigger option will depend on the signal morphology of the external trigger. After the trigger setting have been defined, press the recording button in advance. It sets Motive into a standby mode until the trigger signal is detected through the eSync. When the trigger signal is detected, Motive will start the actual recording. The recording will be stopped and return to the 'armed' state when the second trigger signal, or the falling edge of the gated signal, is detected.
Note: For capturing multiple recordings via recording trigger, only the first TAK will contain the 3D data. For the subsequent TAKs, the 3D data must be reconstructed through the post-processing reconstruction pipeline.
Input Monitor displays the corresponding signal input frequency. This feature is used to monitor the synchronization status of the signals into the eSync.
Internal Clock: Displays the frequency of the Internal Clock in the eSync.
SMTPE Time Code In: Displays the frequency of the timecode input.
Video Genlock In: Displays the frequency of the video genlock input.
Inputs: Displays the frequency of the input signals into the eSync 2.
Lo-Z: Displays the frequency of the external low impedance sync device.
Hi-Z: Displays the frequency of the external high impedance sync device.
Isolated: Display the frequency of the external generic sync device.
Reserved: For internal use only.
