i have unequal steps and pauses,what i did was create a comp with the man in it changed the rotation position for all the limbs,then added an angle control for each,then pick whipped the rotation of each limb to each controller animated the walk with keyframing,now it would be easy if i was walking from one side of the screen to the other,because the image would be still, but my guy is standing cenre stage,and has an uneven timed walk,and i want him to walk from one side of the panoramic jpeg to the other but still be in the middle of the screen.i tryed tracking his walk applying to a null then pickwhip the background to the null only on the x axis but its too jumpy not smooth.may be i should cut the grass out of the image,import it back make it a 3d layer move it infront of the background image,make that still but the background image move,but thats not going to look real.
