Any very structured pattern rotating can cause “blind spots” for the analyzer.Ģ. the same person hand for instance) might confuse the motion vector calculation. “Picket Fence”: A very regular pattern in motion (for example someone wearing a t-shirt with fine stripes) with an object moving in front of it (e.g. As you become an expert user, you learn to predict the kind of material that can cause problems.ġ. The idea here is not to discourage you and tell you it does not work but, rather, to give truth in advertising. It might happen that Twixtor might do poorly in specific instances. This information will be of more use to you as you become more familiar with Twixtor and want to understand how to generate the best possible results. If you have not used Twixtor yet, this section might prove to be a little bit esoteric. You probably want to read about “problematic footage” from our manual that I reproduce below. Our Pro version allows you to roto the skier (frame by frame animation) and then use that to tell Twixtor that the skier is a separate object to be tracked, but even that takes a bit of trial and error with shooting properly to allow that to work. However, I suspect there’s not much you can do to get the ghosting to disappear (even after watching that tutorial), except to shoot next time using a higher frame rate. You can reduce the “gloopiness” by watching this help tutorial. Ah, if you have a lot of motion (or objects crossing each other with a fair amount of motion) then you will see this problem.
