Edit multiple keyframes in Fusion

Hi

I have a shot I have tracked in Fusion. I would like to set the X value to 0 for all the keyframes. What is the quickest way to achieve this?

TIA

If you haven't tracked it as an x/y path you should first convert the track to one.
Then you can just scale the x value to 0.

Or you you could add a transform with an expression for the center position, that says something like

point (0, tracker value y) but then in the correct syntax, that I can't remember right now.

But I have a feeling I might misunderstand what it is you're looking for.
If you set the 'x value to 0' what will be at 0 then? The object you tracked?

I have tracked the shot and have keyframes with X and Y values. I want to change all X values to 0.

Anyone have any input please?

Thanks

With the Tracker in a viewer, right-click in the viewer and choose Convert to XY Path under the Tracker Polyline.

Excellent! Thanks a lot.
