Weird camera movement behaviour
Hello,
I run into a weird problem. I have a composition with a camera and 3D objects. I move the camera from one position to the next over one frame (as in mimicking cuts in a film); so I have keyframed point of interest and position. The camera should move instantly from position 1 to position 2, over one frame. However, it moves over two frames, i.e. there is a two-step movement that the camera makes.
This two-step movement results in strange artifacting of 3D objects when the camera is in between position 1 and position 2 (i.e. where it shouldn’t be at all): 3D text is rendered as if there were multiple copies of the layers near one another.
I have tried changing keyframe interpolation to linear, no help.
The weirdest thing is that in previous versions of the same project this problem didn’t occur. Unfortunately I can’t recall all of the many changes I’ve made between versions, but I checked that the camera and its keyframes are identical in the working and non-working versions.
Any help would be greatly appreciated.
Cheers,
Janne -

Hmmm… Couldn’t you just create a new camera at the second position?

Hold keyframes?

I haven’t experienced your exact problem, but I have run into strange behavior moving cameras in 3D environments. One trick I found (I think from this forum) was to attach (I think parent?) the camera to a null object and move the null object, not the camera (though the camera follows the null object). For reasons I don’t understand that resolved various strange camera behavior and artifacts between key frames. I’m just a novice, but perhaps this is helpful.
