Hi,

I'm analyzing a number of videos in very similar ways. They are videos of a bubble in fluid system, on the same setup with different parameters. Thus certain values are always constant - framerate at 750 fps, pixel size at ~1.3e-2mm/px, origin of XY being in the top left corner (in order to combine methods with Fiji/ImageJ). Is there any way to set these to a default so that I don't need to manually set them for each video? Considering my dataset, this would save a considerable amount of time.

I'm also only tracking along the x-axis, so that the y-positions are never of interest. Thus when I export I either manually select time and x to copy-paste or manually remove the y-values from the table view. Another question is whether it is possible to fix the XY axis so that it stays at the same spot, even when I track along the x-axis? I.e. is it possible to track parallel to the x-axis rather than along it?

Also, Fiji uses the top left corner to denote (0,0) in an image, and then moving down increments the y coordinate positively. Is it possible to do the same in Tracker? I.e. mirror the coordinate system over the x-axis?
