    Hi, I tried this:

    The manual says that expressions can’t be used directly to affect a mask path, but that mask path can be linked to other properties to affect it. So, I made a layer called Mask Repo 1 and pickwhipped the mask path of mask 1 to the position property of layer: Mask Repo 1. I was hoping then “to change the position on Mask Repo 1 to globally reposition the keyframes of Mask Path 1. But, I get an error message, which says: AE warning: “Object of type 1024 found wheer a Property is needed.”

    This is the expression produced by pickwhipping the position property of Mask Repo 1: “thisComp.layer(“Mask Repo 1″).transform.position[0]”

    Any thoughts?

    Thanks,

    Eric

    thisComp.layer(“Mask Repo 1”).transform.position[0]

    Hi Eric!

    Try some of those:

    https://aescripts.com/tracker2mask/

    https://aescripts.com/?s=mask

    Those are the things that came to my mind when I read your post.

    Those are scripts not straight expressions but they can do what some expressions can´t.

    Hope it was of some help.

    Cheers.

    Hi Adriano,

    Thanks very much for your suggestions. Along with mask automation script, there was another that allowed the global key frame changes I was looking for. Between the two of them it’s going to really speed up my masking.

    Thanks again,

    Eric
