  • pasting masks contains unwanted transforms

    Posted by James Hooey on February 11, 2009 at 9:41 pm

    I have several intricate masks (over hands and face) of a subject and want to paste these masks to another layer (lets say a photo layer for adding a overlaid texture). If I scale this photo layer or rotate or change position to set it up as I want and then paste the mask….the mask takes on these various transform properties….

    first off, why is this?? Seems like the mask should be pasting with the original properties (scale,rotatation,etc.) regardless of the transform properties of the layer it is being pasted to.

    Secondly is there a way around this?

    Sorry if this doesn’t make much sense but if there is any thoughts I would be happy to hear them!

    All the best,

    Figured out a probably less than elegant solution….

    Paste the mask to a default white solid….use as a luma matte over the rotating, scaling moving position photo layer….

    works, but is there a better way?

    Hi Dave,

    Really, that is the problem I am having….I do not want to have to paste the masks onto a similar sized, positioned layer.

    The solution I have come up with is to copy and paste the mask to a white solid (which is the same size, PAR, rotation ect.) as it’s original layer and then use this as a luma matte over the photograph.

    In my particular case it is an extreme version of Andrew Kramers’s demon face warp style effect. Use a texture to add veins and texture to a persons face.

    The persons face and hands I masked out by hand (10 seconds long…carpal tunnel set in!!) so I had good tight masks to apply other effects to. I then used a texture photo which I keyframed the movement to match things like the movement and rotation of the hands (I’m trying right now to get Mocha AE to do this…but not having much sucess). Finally by using the original tight masks of the face and hands and duplicating them to a white solid and using that as a luma matte over the texture photo I am able to have moving textures that are perfectly matted to my hands/face.

    The shot is far more complicated than Andrew’s orignal demo. The hands move on/off screen – in front of the face – head turns ect. Which is why I masked out everything very tightly for the full 10 seconds of the shot. The end results are working but the keyframing of motion by hand is still not coming out as tight as I would like so I am looking at some tracking ideas…point trackers won’t work…Mocha AE….seems to have issues too with the track. Hand keying may be the only solution.

    As for the mask problem….solved that anyway!

    Again though…if there is a more elegant solution I would love to hear it!!!

    LOL, for sure!…but it’s so hard to find actors with 5 inch round eyeballs and get them to fit inside a television 😉
