dont get me wrong, 3D tracking is awesome, but where did the option for 2D tracking go? 3D tracking is way too unnecessary for most of my compositing needs. Is there an option I have over looked? or was it taken out.
you can apply a 2d track to any object in your scene by selecting the marker and the object and then pressing the “apply follow track” button in the movie clip editor.
Nazg-ul will put it back at some point… he’s thinking through the 2d workflow at the moment.
Shouldn’t that just be a “Follow marker” constraint? -.-
Shouldn't that just be a "Follow marker" constraint? -.-
They’re in already in 3d space , but you need to have “solved” the camera,
what’s on the cards is using a movie clip in the compositor…
do you add a new node to “follow marker”? (duh) , especially when the current workflow in the compositor is flawed and under review for using different sized footage etc… when you “follow marker” does it do it relative to the movie clip? to the scene? to some new concept of canvas? how does that work when the movie clip may already have been transformed/rotated whatever?
Does it snap the center of you footage you’re constraining or relative to some arbitrary “anchor” point?
Should that itself be keyframable? within a range?
The answers to these are each simple enough, but you rapidly get these and a lot more questions, each of which needs some thoughts to merit, implementation, flexibility and possible future development.
Also, which parts do you do where? what belongs in “movie clip” editor and what lives in the composite (or indeed the 3d scene)
Bear in mind that matte creation, and stabilisation are already pencilled in for the movie clip editor…
We all know what sort of feature this should be but someone has to code it and take into account all the things we may not have thought of as well…
All I’m saying is that it’s more complicated than it first appears, needs design, Nazg-ul is on it and has done pretty well so far…
all right. good to know its coming back. no the “apply follow track” option just snaps your object to the corresponding bundle(which have no movement)
in the mean time i will have to use the old version.
thanks
ok, then it only works before you have solved the camera. 
that does not work either
Once you’ve tracked your point with a marker, add an empty to the scene, click the marker (make sure it’s actively selected) and then click the empty in the 3D scene, then click ‘Apply follow track’.
Doing the above will add a constraint but nothing will happen, to solve that go to the constraint panel, turn of ‘default clip’ and make sure it’s set to track.
Now the empty should move with the X, Y coordinates of the marker.
EDIT: It’s also worth noting that you NEED a camera in the scene in order for the empty to move at all.
thanks a lots that’s very helpful
