I’m trying to solve a track with the 3D camera tracker.
Whereas it’s pretty solid through the clip, there’s small bits with jitter because the software
didn’t get it correctly. When I put in objects/replace the background with 3d elements they
will jitter when this takes place.
I wondered if I could fix this by using the smooth expression on the camera keyframes after
the track, but for some reason this expression messes up the camera’s angle.
It will randomly spin around when I apply this expression and I’m guessing it has something
to do with the orientation property.
The funny thing is, if I apply this same logic to 3d nulls but use the x/y/z rotate values instead of the orientation values it works fine. There’s something about the “orientation” parameter that doesn’t like this expression. When I’m animating in a fully cg workspace my solution is to make a bunch of 3d nulls and parent my camera to them, then animate the x/y/z values of these nulls to move my camera, after which smoothing these values. However, when I’m analyzing shots with the camera tracker it applies the rotation values to the orientation of the camera instead of the x/y/z rotate.
