OptiTrack - 'eSync 2'
Synchronization & Time Code for your motion Capture DataUse just one OptiTrack eSync 2 per motion capture system to synchronize your Ethernet cameras with almost any signal or source with the eSync 2. Cameras can be synced to professional video sources like Genlock signals, and can be triggered to record from general-purpose inputs and software commands.
Utilise the sync output signal or trigger with a DAW for biomechanical force plate data alignment. Highly accurate frame timing can also be achieved with SMPTE Time Code for ease in editing and logging.
One eSync 2 per motion capture system is all that is needed, and all cameras align within a very precise ~+/-5µs of the input signal. The PoE Ethernet connection allows an eSync 2 to be located almost anywhere in a lab or studio, making it easy to connect with/to source signals.#
With convenient output signals that can mirror most inputs, you can place the eSync 2 in the middle of an existing setup, or convert signal types for greater system flexibility.
Automatically measures and reports the frequency of signals connected to its inputs. This enables fast and easy confirmation inputs have the frequency expected.
Genlock sync inGenlock your OptiTrack Ethernet cameras to an external video source via SD Black Burst or HD Tri-Level analog input. All modern SD and HD sync inputs are accepted for easy integration in professional studio environments. Genlock is ideal for syncing mocap data to live-action media, including on-set capture, camera tracking, reference video, and head-mounted face mocap cameras.
General Purpose sync inIsolated - Used when the sync source is above normal logic 3.3V, or has a different ground reference. Recommended as the default input for general purpose syncing.
High Impedance - Three high-impedance digital inputs are available for sending sync signals from an external device to the eSync 2.
General purpose sync outFour digital outputs are available for sending sync signals from the eSync 2 to external devices.
SMPTE Time CodeStamp recorded and streamed motion tracking data with SMPTE Time Code for compositing with other media in post. Time Code support in Motive:Body includes FBX, C3D, and NatNet. Motive:Tracker support includes CSV, NatNet, and VRPN.
Plug-n-play Shutter glasses supportGeneric 3D shutter glasses support is provided by offsetting the camera's IR Strobe. Connect video cards that support a stereo output signal to the Sync In, and a shutter glasses signal generator to the Sync Out. Use the adjustable software offset to avoid interference between the mocap camera strobes and the shutter glasses.
VESA input and output connectors are provided for graphics cards and IR emitters that do not have BNC connections.
