(Yellow Boxes) are the start of new data streams. The (Green Boxes) are intermediate steps. The (Blue Box) is the final step.


Photogrammetry Pipeline Overview

This page is the guide for you if you answer “yes” to any of the following questions:

  • Do you need to render something in post and get it done fast?
  • Are you new to post-production and want a series of steps to get you going?
  • Did Previzion drop frames while rolling during a take?



  • Previzion
    • Captures camera tracking data and outputs camera data to *.dae (Collada) file
  • Quicktime Pro
    • Converts all captured video (to be used and played back in Previzion during a take) to a sequence of still images which Maya can read
  • Take Converter
    • Converts the *.dae take file into a file format of your choice
    • For this example we’ll be converting to the Maya.ma file format and rendering in Maya
  • Maya (or 3D application of choice)
    • This will re-render the 3D material to a separate sequence of still frames of the background elements only
  • Your choice of Compositing Programs
    • With this software you’ll composite the keyed camera feed and the rendered image sequence from Maya




  1. Load up your desired 3D scene into previzion

  2. Capture a take with Previzion

  3. Use Take Converter to convert a *.dae file into a camera in a Maya scene file (*.ma)

  4. Open 3D scene (the same one loaded into Previzion when creating this take) and import the new PrevizionCamera.
    1. First, open the scene that was used to generate the FBX file (the FBX loaded into Previzion) in Maya
    2. Second, import the scene file that was created by Take Convert (see step 3). This file should contain the Previzion camera
  5. If there are any background plates… use Quicktime Pro (or your compositor of choice) to convert the background plate(s) to image sequences
    1. This can be done using any compositing program
    2. http://lightcrafttech.com/support/documentation/post-production-workflows/rendering-video-as-texture-in-maya/
  6. If there are any background plates… assign the newly generated image sequences to the video plate geometry in the 3D Maya scene

  7. Once all cameras, objects and textures are set, you’re ready to render!
