  • .ai files shaking while using continuous raster.

    Posted by Euan Preston on May 11, 2009 at 12:08 am

    Hello,

    I have a comp containing a large .ai file ( a map of earth) in which I begin off with a CU of the UK before dollying back to a wide shot of the world.

    In order to prevent the map pixelating while in CU, I’ve enabled continuous raster for the map layer. However CR causes one of the layers within the .ai file to shake and judder (both in RAM preview and render). The problem is relieved when I switch off CR, however this means my opening shot is pixelated.

    Any help would be gratefully recieved.

    Thanks Dave, only thing is it’s quite a copmlex comp in 3d space, so a camera is a necessity.

    As a workaround, I’ve exported the offending layer separately and the composited it back with the rest of the .ai file in AE. Seems to have solved the issue, however it would be interesting if someone has some suggestions why the problem occurs in the first place.

    I was having the same problem with an illustrator file shaking in after effects. I followed the link Dave posted and it says you can change the antialiasing setting to more accurate rather than fast. when i did change it to more accurate my wiggle / jiggle / shake problem disappeared. But it does take a lot longer to render.

    I realize this is pretty old, but I had a hard time finding the answer to this problem online and this thread came up but did not satisfy.

    The actual solution:

    Right click on the problem vector source in the project window:

    Interpret footage > Main > More Options… (the tiny button in the bottom left corner)

    Set antialiasing to “More Accurate”.
