Not necessarily.  And I don;t know what you mean when you say "ALL" layers.   You need to include any layers that other layers may be dependent on.  But in general you would to be sure you're not breaking any dependencies in the compositiopn you're taking them OUT of.    Like myl said.  You need to be very specific.  Show all the layers modified properties.  What adjustments you're using how they are affecting layers.  Even what's in your other comps could be affecting it.    It's not a catch-all rule to say "all layers have to be included"  "ALL" is a variable, it means different things at different times. It was just a way to try and isolate where your problem is so you can start looking in the right place. Then, hopefully you can start fixing whatever needs to be fixed. Could be simple...could be frustratingly complicated and make you want to start all over. You need to show all of your  relevant settings. relationships...basically anything you have modified.  With all you've got going on in that comp it's going to be A LOT.   Fingers crossed that it's as simple as clearing your cache. ...

Two of your layers (bottom two) are parented to a layer (31) you are leaving out of the pre-comp.  Also you have several adjustment layers.  When you pre-compose you are losing all of the translation and effects from those dependencies.   That's probably where you problem is.  Also could just be a memory/cache issue as Myl said. ...

OK.   Yes if it's a moving video then you would need an animated mask or rotoscoping but I though your descriptions said there "No motion" Reading your desctiprion carefully again I'm certain I don't understand. In fact if not for the words "locked daown" and "tracking" it sorta sounds like you you could just animate the opacity.   "An image dissolve in inside (over?) a background and dissolve back out"??? What does "inside"  mean?  In AE layers fade in and out OVER each other, not inside. And why create a shape in Photoshop, export it is as .png into AE when you could create a "shape" directly in AE?     And as for you statement about  "AE is not capable of doing this - shapes cannot not roto out or delete pixels within the shape" What are you talking about?  Do you know?  I mean you absolutely can using a matte or the Set Matte feature and both sahpes and masks can most certainly be animated.  And there are some "auto-roto" options in AE.  There's also the AUto Trace feature which I've gotten some pretty good results from in the past.   Both Rick and I mentioned trying a set matte and while I might not be a real expert,  I can say for certain Rick knows what he's talking about. I know much less than Rick but I know this.   Whatever you were trying to do and whatever you did I'm glad you got it worked out but to me it reads like you figured some incredibly complcated way to fad one layer on over another layer.  That or you just phrased your question badly.     Yeah...we're on different pages for sure.  Even you descrition of how you solved it makes zero sense to me.   but...  there are indefiniable variable so...   Anyway Good luck. & glad you fixed it.   ...

My guess is that you haven't closed the mask.    As mylennium said you need to upload proper screen shots with close shots of the and your mask settings revealed.  A glared , angled, smartphone shot isn't worth much and it's not a good way to ask for help. Unfortunately, as a brand new user you verbal assurances aren;t worth much either.  It's common that new users think they've done something they haven't.  By seeing your settings we can see for ourselves what you've done.    ...

You need to prepare the file in illustrator first to make sure it will have editable layers. You do that by clicking on the file in the layer menu then choosing release to layers.  Here is tutorial on how to do that https://www.youtube.com/watch?v=ez9BGTGs6cE     You can save the file as .ai or .psd If you did this correctly when you import it into AE you should get prompt asking if you want import it as a single file or a composition (for an .ai file)  choose composition set footage dimensions as "layer size".   Open the new composition and your three layers will be there all on their own layer. The import process will be worded slightly different for a .psd file but in theory it's the same.   The search I did for the tutorial was "importing editable layers to after effects" That search will return results for .psd files as well if you're interested to see the difference   BTW duplicating the layer twice and then masking each one and centering the anchor points.   For that just search for "how to use masking in after effects" For moving your anchor point to the desired position (so the layer "rock back and forth") use the Pan Behind (Anchor Point) Tool on the toold bar.  Shortcut "Y"   ...

Yeah it lloks like you need some scripting for that.   Have you looked into the sourceRecAtTime() expression?  It automatical resizes a shape layer so that it always fits perfectly around a block of text.  You could parent the lower line to the shape layer (with its anchor point left alaigned) and the turn off the visibility of the shape layer.  But I'm not sure if the expression will work if the shape layer's anchor is not centered, you would have to test it and see. https://www.youtube.com/watch?v=In4miXUdxko&t=101s   If the anchor does have to be centered you could try applying Create Nulls From Path in the windows menu. That will apply nulls to every vertex on the shape layer that will stick to them wherever they move. Then you could parent the lower line to the left null and it should follow.  You might want install the extended version of CreatNullsFromPaths which is here https://lesterbanks.com/2017/10/create-nulls-paths-extended-features/ ...
