Camera Shake Movement Output

#1

Hi guys,

I’m sure (/hope!) there’s a simple answer to this one - Is there a way to “get” the value that the image is being offset by from a CameraShake node, so that you can use it to link to other values in the same way one can from a Tracker? My problem is that I was a lens flare “Position” value to be linked to the camera shake, so my hope was that I could somehow get the offset caused by the CameraShake and add it to the Position value (and it would change each frame, thus mimicking the movement).

In the UI there’s no obvious place where this value exists - is there an expression I can use to grab that offset, or does it not exist? At the moment I’m going through the slightly lengthy process of piping an image of some tracking markers into the CameraShake node and tracking one of them, but there has to be a better way?!

Thanks,
Dan

the camera shake is only a gizmo with one transform node inside, so you could create a new user knob (“2d translation”) and then “pick” the translate from the Transform inside the gizmo. then you can link the flare to this new user knob

or you could hit the “copy to group” node and go inside the group and link from there to your flare

That’s exactly what I was after Michael, thanks very much. I went for the copy-to-group method and linked from there with an offset in the expression, worked a charm :smiley: :bounce:
