so, i'm doing a project where i'm analysing parkour rolling absorsion efficiency and i need to analyse some videos with non ideal angles (videos recorded in a 'skate fashion' way, or where the camera is moving while the motion is happening). i want to know how i can Track these videos with most accuracy.
thx! Louis
(if someone also know, how accurate is tracker? in therms of post-graduate physics analysis)
You can analyze videos where the camera is moving by letting the origin of the axes follow a fixed object in the video. You may also need to use an offset origin with a second fixed object if the original (origin) fixed object moves off screen. You might look at how Rhett Allain handles a moving camera at https://www.wired.com/2012/07/calibration-points-in-tracker-video/. There are probably other youtube videos that deal with this situation.
The accuracy of Tracker depends almost entirely on the quality of the video, the calibration and the care with which you mark positions and correct for distortion. Every case must be estimated separately.
