Hasta La Motion!

Hi, does anyone know how to convert/import tracker data from shake to Nuke? enyone ever did this? anyway nuke’s tracker is quite slow and easy to shift away… i don’t know why, even with very clear dot/mark on face and not many light changing and just little movement (not panning but turning a head a bit with slow motion and tracking/marking is clearly visible from start-end, also it’s noticable black colored mark on white face )… frustrating . So i’m doing it in shake which is more ‘sticky’ just ‘one’ single click and done. ok i have the tracker from shake and i want to do the compos in Nuke for many other reason. Anyone have suggestion ?

thanx
