1.General presentation

DisparityKiller is a post-production software designed for the correction of stereoscopic images, which allows to correct automatically all geometrical disparities inherent to a 3D shooting.

Applying corrections to rushes allows to watch the movie in its early stages in stereoscopic edition without cerebral tiredness or eye-strain. Thus, it prevents from disinclinations due to tiredness and clarifies eye-strain causes resulting from sequences choice or edit point.
DisparityKiller turns out to be essential to validate all post-production operations until the final version, to deliver a movie free from disparities to the viewers.

The correction function of DisparityKiller v1.0 corrects the following issues:

  • camera slewing
  • camera translation
  • lens magnification
  • keystone effect due to converging cameras.

It is essential to eliminate these problems from the stereoscopic pairs to ensure the visual comfort of the viewer.

The correction function of DisparityKiller v1.0 is calculated on one or several images of a shot and applied throughout the shot.

Please note that you will have to ensure the synchronisation of your sequence to obtain a good correction.
Besides, DisparityKiller is not designed to handle variable geometrical disparities in a shot (due to a change of convergence or focus during the sequence for exemple).
