    is it possible to convert tracking keyframes which are written by AE Motion tracking as a mask?
    The mask should be available for further animations.

    If I get what you want, try this.

    Select and copy the Motion Tracking keyframes you want to convert into a mask.

    In the layer you want the mask, with the Pen tool, make a point to set a keyframe for mask Shape. (You need one keyframe to paste onto)

    Twirl down exposing the mask, then Mask Shape. Select the Mask Shape and Paste in your Motion Tracking keyframes. You should have a mask shaped like your tracking points. You can animate the mask shape over time with keyframes (see help files).

    Hope this is what you wanted to do.

    you get e x a c t l y what I want, but…
    My first suggestion i had, to fix this problem, was the same way you show me.But the only result was, to have a new tracker in this layer.
    I try lots of combinations, trying to use a expression and so one.
    Nothing works. Where is my mistake?

    Copy those Tracking Keyframes.

    Here’s the most important part.
    You need an exsisting mask to paste the keyframes onto.

    So make at least one point with the Pen tool (or more) or use the Rectangular Mask Tool or the Elliptical Mask Tool to draw a mask, any mask, in the layer you want to copy the Tracking keyframes onto.

    Select the layer. Hit “m” on the keyboard.
    The Mask and Mask Shape (below it) will drop down below the layer. Select (highlight) the Mask Shape, and Paste those position keyframes. Presto, you should have a mask in the shape of those tracking keyframes. It just worked for me. No tracking keyframes if you paste onto a MASK SHAPE. Good luck.

    Hi again,
    thank you for the very detailed describtion.
    I am a little bit familiar with the function to copy masks into masks,
    use lot of times the workflow between AI and PS with AE.Of course, i created a Mask at first.
    In this case it dont works.Its the same, whether I copy the keyframes in the mask shape, there no different, whether the Stopwatch ist activate or not.
    It always create a new Tracker.
    So what, I think im standing on the line, dont believe, there ist a different between the english and german version.
    Thanks for your helping
