![]() My students use it to analyse motion is action movies as a project. I've done projectile, 1D and 2D conservation of momentum. ![]() You can adjust the frame rate to accomodate high-speed (or slow motion) cameras - you can see the hummingbird's wings!.Works with built in web cams and cameras attached with USB cables.Very easy to use, students can get a good projectile motion analysis the first time in about 10-15 minutes from shooting video to graphs with speed and acceleration.Not too difficult - a good student exercise. Since you can plot multiple points and create calculated columns, you can subtract the motion of the camera by using a fixed point and use a little relative motion.Logger Pro allows for moving the origin.In our school board we have Logger Pro and I just gave a short presentation on using Logger Pro for video analysis to physics teachers. UNCG is prohibited from executing prohibited clauses in software agreements. Okay, I just read this so I haven't tried Tracker yet. Information Technology Services (ITS) provides a variety of software services, including the deployment of applications for on-campus and off-campus use, licensing and acquisition information, and pre-purchase review of software considered for adoption. There are some other video analysis tools out there, but these are the only two I would choose from. I really like tracker video, but it seems like it might be a little more difficult for students to get into. Not a complete comparison, but enough to get you thinking. Built in modeling - don't know how to use this.Tracker can track point mass, center of mass, vector Video filters - brightness/contrast, special effects, deinterlace, noise reduction.Tracker can change the number of frames you look at as well as the starting and ending frame. Can track multiple objects in a video.I don't think that Logger Pro can do this, but I could be wrong. Can rescale each frame, move the origin, rotate the origin for each frame.Note that I am still not an expert on the use of Tracker Video - there are some features I really don't use (but should). ![]() Instead of looking at the cons of Logger Pro, let me just look at Tracker. The site license allows students to install it on their home computer. Not really a pro, but Logger Pro is pretty cheap for a school.If you video a ball falling and also use a motion detector, you can "sync" the data. Integration with data from other sources.Good graphing and curve fitting utilities built in.The students were already familiar with Logger Pro. The primary reason was that the tutorial was for a lab course. In the previous tutorial, I used Logger Pro. Why did I use Logger Pro? Why not Tracker Video? Here is a quick comparison of the two. I recently posted a tutorial on using Logger Pro for video analysis. ![]()
