Hi,

I want to use an expression to globally change all mask path positions in the x and y across a series of key frames. Any help would be appreciated.

Thanks,

Eric

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:

http://aescripts.com/tracker2mask/

http://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 canĀ“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
