Overview

This standard is about recreating the camera movements that were used to shoot the background plate.  It involves working with basic line up geometry and associated scene data that have been captured on set in order to ensure a good match with the scene. 

This is relevant to those involved with matchmoving and 3D tracking and also covers the use of real-time tracking solutions.

Performance Criteria

You must be able to:

  1. interpret information from background plates, floor sheets and camera data to identify matchmoving and
  2. 3d tracking requirements calibrate each lens to identify and remove distortion
  3. draw vectors to determine access planes within the plate 
  4. set up tracking scenes which comply with on-set camera data
  5. utilise industry production tracking tools to interpret and track interacting factors on the project.
  6. make sure tracking points stick to appropriate points on plates for the length of the shot
  7. check for errors and refine as necessary
  8. align camera solve to improve match-moving and 3D tracking
  9. composite the tracking sequence for review
  10. share work with others when appropriate and constructively use feedback to revise tracking when required
  11. convert plates into various formats for use with inhouse software
  12. follow process for the planning, setup and calibration of real-time tracking solutions

Knowledge and understanding

You need to know and understand:

  1. how and where to obtain up-to-date floor sheets and camera data
  2. the differences between parallax, nodal, non-nodal and mixed motion camera movement and how parallax helps camera tracking software calculate an accurate track
  3. how to use tracking software
  4. how to create and use distortion lens grids
  5. the principles of line up geometry and how to use it for matchmoving and 3D tracking
  6. how to measure and recreate focal length
  7. how to identify and correct errors in tracking
  8. how to render out geometry
