Changing the z value for the projector does not create a projector keyframe

[herman@…]

Creating keyframes in the compositor: When I change the z value in the
projector's parameter window (press "?" to show it), no keyframe is shown on the
timeline.

How to reproduce:

Load a video clip
Toggle "generate keyframes while tweaking" (key-shaped button)
In the compositor, toggle "adjust projector automation"
Toggle the "?" button, to show the projector parameter dialog.
Change the z value in the projector parameter dialog

With "generate keyframes while tweaking", any changes in the projector parameter
dialog should create a projector keyframe. But that only happens when I change
the x and y parameters, not the z.

Changing the z value for the projector does not create a projector keyframe, it
creates a "projector zoom" keyframe. Even though the z value is grouped in the
same dialog.
The z value is called "projector zoom" in the view menu, and is considered a
different keyframe. If I enable View->projector zoom, the z changes become
visible as a dot on the red projector zoom automation line.

This breaks the principle of least surprise. The projector automation

parameter dialog ought to have separator between the z and the x and y, and
label the z input "zoom".

Totaly nasty workaround:

copy the keyframe. Right click on the plugin you want to paste it to... move it
up/down till it is in the position of the keyframe you wanted to copy... paste
the keyframe

the last comment was meant for bug 47... my mistake

[andraz.tori1@…]

one way of solving this would be to have a button for "create camera keyframe"
inside the toolwindow for camera and projector... pressing the button would
create both keyframmes

I have a proposal:

Option under user interface menu, to connect zoom and position keyframes of
camera and projector. unfortunately it is a lot of work to take care of all the
possible cases.
