I am using tracker to analyse a ball falling, rolling down a plank and constant motion and our school computer system will now open tracker and when I import a video it will load to 20% and no more. The videos are AVI and about 3M and I dont know what to do. I have had to install the xuggle video engine on all machines and this has got me to the loading stage but only 20% Please help as I am using this in 3 days time and I am lost. I will attach the screen shots of some issues that i think i have solved with Xuggle.
