The role of the CAMTracker (D2) software in the entire workflow is to process the camera images and tracking data and then send  to D2 for real-time 3D composition. Specifically, the processing of the picture involves color space transform, camera picture correction and real-time keying, MASK processing and projection mapping, and the processing of tracking data involves data filtering, coordinate system conversion and transmission protocol conversion. CAMTracker（D2）virtual production workflow： 1.   The first step is to set the camera screen, and CAMTracker provide a tracking camera (ie CAM0) and 4 fixed cameras (CAM1-4) video input  . You can directly click the red CAM0 button in ...

new function： 1.   OCIO color space transform. This function has already been added to UE4. It is mainly used here to convert the color space of the camera image. The professional photography-related technology here is simply to convert other color spaces into the Linear linear color space used by the computer 3D engine. Different brands of cameras can use different configuration files. Of course, you can also use the corresponding LUT for color correction. The specific function can be parameterized in the description of TD: https://docs.derivative.ca/OpenColorIO_TOP 2.    Lens calibration. Because the camera lens will inevitably cause various distortions to the original shooting picture, in ...

  Virtual Production Workflow：  1.   First of all, determine the tracking system you use and the hardware of the video output.    For the tracking system, it is recommended to use a more professional tracking system, so that the final picture stability can better meet the requirements of film production. For the vive tracking system, it is ok to test it , but we recommend you use a more professional tracking system if you has higher requirements for picture stability . For the way of outputting the picture to the UE, for routine testing, you can use Offworld’s NDI/Spout plug-in to ... Read more

Let’s first explain the purpose of CAMTracker in virtual production. As a companion software for virtual production, CAMTracker is mainly used for processing camera image keying, tracking system input and coordinate system conversion processing.  CAMTracker can output keyed images to UE through NDI, Spout or professional video output card, support Genlock locked frame output through AJA or Deltacast brand video output card, and support to output LTC time code synchronously with camera time code. Tracking data can be output to UE through OSC or FreeD protocol. Through the OSC, the six degrees of freedom of the tracking camera and FOV ... Read more
