convert left-handed camera position and rotation keyframes to right-handed
I received a bunch of matchmove cameras from pfTrack that are in left-handed coordinates (i.e., positive Z is into the screen).
Does anyone have the correct expressions to convert the position and rotation values to the right-handed coordinates that After Effects prefers.
I plan on simply creating a new camera and assigning the appropriate expressions to the position and rotation values to pull and convert from the original left-handed camera layer.
Thanks in advance!
Kindly,

try simply making the values negative with an expression like this:
-value;
if that doesn’t do what you need, let us know.

Would that it were so easy!
The maths seem to be rather more complex than that:
