Here are various examples of Matchmoving and image-modeling techniques. Matchmoving sequences here were done after the shoot, and there were no trackers of any kind placed in the environments. Tracking was done with Boujou or Syntheyes and it involved combination of automatic and manual tracking and, once tracking process was started, it needed extensive re-calibrations and reference photos taken long after the shot was done. Initial photography wasn't done with 3D CGI in mind. Some sequences were then stabilized and re-timed.
