In this tutorial, Russ Andersson demonstrates how to address rolling shutter issues using SynthEyes. He begins with a conventional tripod shot, running an auto tracker to generate a field of trackers, and utilizes a script to randomly color these trackers for better visibility. Andersson explains the process of cleaning up non-useful trackers, especially those on clouds and moving cars, to improve tracking accuracy. Despite initial high error rates, he activates the rolling shutter correction feature in SynthEyes, significantly reducing errors. By comparing the actual 2D tracker positions with the calculated 3D positions, he illustrates the impact of rolling shutter. He emphasizes the importance of matching CG effects with the rolling shutter characteristics of the original footage to maintain image quality and avoid labor-intensive hand corrections. This approach is highlighted as a practical solution to handle motion blur and rolling shutter distortions without resampling the image.
