Hi i am quite new to after effects i have only been using it for a few months im using after effects cs4,here is my problem i am trying to track a picture frame but when the picture goes out of the scene,the motion tracking path just goes crazy. It works great when the picture frame is in the scene
the camera is pointing straight at the picture frame, works perfect, but when the camera turns right , and the picture frame is no longer in the scene, my track path just goes wrong.
How do i stop this?
Do i have to make a seperate motion tracking null object? or is it something to do with backwards tracking?
Any help on this would be great i have serched youtube,adobe for the answer but i cannot find it anywhere
Yes, that's just how it is. AE has no way of knowing where those markers might be and even tracking points separately and in segments can only take you so far. You'll have much better luck trying such things with mochaAE, which comes with the main program. IUt assumes that all points would be part of a plane. If even that isn't enough, then probably 3D matchmoving tools like SynthEyes are your only option...
Wow that was a fast reply thanks - I have never used mocha but i will give it a go now
