access the velocity of a 3D camera via expression
Hello Guys,
I really hope someone can help me with this, I have an idea of what i want to do, but since the only expressions I’ve ever used are wiggle and smooth, I have no idea of how to accomplish this!
I’m currently working on a steadycam-shot, but it still isn’t steady enough, so one thing i’m doing is of course stabilising the position of the picture. But what I also want to do is stabilizing the velocity of the movement, because you can still see the steps of the operator.
So I tracked the camera and now my idea was to link the velocity (the difference between let’s say the cameraposition 3 frames before minus the cameraposition 3 frames after the current frame) of the solved 3D-camera to the frame rate in Twixtor or Kronos. So when the camera moves slowly, the frame rate will speed up.Has anyone got an idea on how to do this? That would be really really great!
Thanks for your help!
