Hey everyone! I'm setting up a behavior experiment with some insects. The insects are going to be in a 30x20x30 cm glass box, and I'll film them from above. One of the objectives is to register the total distance of the insect's movement during the length of the experiment. Is there a way I can track the movements of the insect? I was thinking of something along the lines of placing a layer on top of the video, and following the movement with my mouse, which would leave a line. At the end of the video, that would leave me with an image that can be imported into Photoshop and the line measured with the ruler tool. Like this: 1 would be the glass box, 2 would be the insect and the traced route, and 3 would be the image imported into PS CS3 and measured. The scale would be easy to get, since I just input the number of pixels that the 30 cm side measures and set my scale. BTW, the ruler tool only lets me measure the distance from point A to point B. Is there any way I can measure the whole route in one motion? I'd hate to have to add all the different lengths. Tools I have available: Photoshop CS3, Final Cut Express.
