Thats it.. there are no adjustmants layers that would be influancing it, no resolution preservation from precomps.. And it happends on just a few frames randomly.
when I precomp it, or turn some layers off, it goes away. But that is not an option..
I thought maybe it is just some preview engine glitch, but it renders out as well.
Im on AE CS6
Not without a screnshot with all changed properties revealed and an explanation that gives some details. I have no idea what you are doing or what your layers contain when they 'change resolution.' I don't even know what that means. Size? Scale? Preview? The only thing I can guess is that it's an openGL driver problem. Turn off open GL previews and let us know.
Still not seeing the timeline but I'd bet that you are just looking at adaptive resolution. Purge your cache, turn off disk cache. That should do it.
System Specs? Memory? OS? Still very little info go to on.
Ok, I turned off fast preview, purged all memories, and caches and it still didn't help :/
Here is the fullscreen screenshot. I opened 2 comps. Its the same frame. On the left, you see the comp that introduces the bug, on right is the inside of the trubled comp looking alright..
Im on 8GB memory i7 processor windows 7-64bit system.
Update didn't fix it, but I found out I must have accidentaly clicked "preserve resolution when nested" option in comp settings. It shouldn't be a problem since (as you can see on screenshot above) I had both nesting and nested comp resolution set to full, but turning it off fixed it.
Thanks for your support
