How to mask a donut (with a hole), that is moving... sync the inner and outer mask how?

Hi, still having problems with this...

I have a donut....(with the hole)

The donut is animated, moving up and down.

I masked the outside of the donut, pen tooled it,  and that looks fine.

I then masked out the hole, and I'd like to sync the hole mask with the movements of the outer donut mask.

 

I can't get parenting to work.  😞

 

I made 2 seperate comps, but can't get them to sync.

 

I also placed both masks in the same comp, and can't get them to sync.

 

Thanks for your advice! I'm baffled as always.

Correct answer Letty2019

I posted a new question in a post, to keep it simple.  My wording here makes us both go off in different directions.  I'm a novice, so that's why its hard for me to understand. Sorry.

Please close this one.  I posted a new simple question a few mins ago.

Thanks for your time, again sorry for the confusion.

Letty.

I think the confusion is more about workflow than the process.  It would save a lot of confusion if you could post a screengrab of your project, with all the animated properties visible in the timeline.

 

It sounds like you're trying to mask the animated object, after you've already animated it?  And you've animated the mask path to follow the animated donut?

 

If the image is a photograph, you just do the masking before you animate it - outer edge and inner hole.  Once the image is masked, you then animate it with standard transform tools like Position and Rotation. The masks will move with the animated image.

 

You could even cut the donut out in Photoshop if you wanted to, before importing to AE.  

 

If you've already animated the donut and don't want to lose that work, you can precompose the donut layer (make sure to "Leave all attributes in [comp]" ) which will create a nested composition with the static donut layer in it.  Mask the donut outer edge AND hole within the precomp, and remove the masks in the main comp.

    Hi, will this work:  (the donut is a video clip btw)

     

    Start from scratch, make the ext mask and then the hole mask, (don't animate) then pre comp both....then.... copy and paste the old animation key frames from the original donut mask to the new pre comp'd set of masks?

    You said earlier it was a photo, but that's okay.  So long as the donut doesn't move in the frame at all, you can just create a single mask to cut it out.  If it moves in the video clip, or the camera moves, then you will need to animate the mask.  It sounds like that's what you've done, but again, only guessing until you post a screenshot.  

     

    The rest of your questions can't be answered until you clarify the above - is the donut moving or perfectly still within the source video file?

      You have a fundamental misunderstanding here. No need to "sync" anything. You simply create the donut shape as a static item inside the pre-comp, the nanimate the pre-comp layer as a whole in the parent comp. Other than that there's a million otehr ways to do it, including simply applying a super fat stroke to a mask to create a donut if you realyl need to animate the mask shape itself, using the puppet tool, the Reshape effect and so on.

        Hi, Can you please reccomend a video tutorial on this?   I'm having difficulty understanding.

        I'm not working with a shape of a donut, I'm working with a photograph of a real donut, and am masking that. (if that info helps?)

        I've been searching videos and can't find the right tutorial.

        Thanks! 🙂

         

        I forgot to mention,  I've already completed the outer mask and animated it.  My problem is I want to add the center hole mask, but have that sync with the outer mask.  Thanks for your thoughts.
