Hey all,

I've always seemed to run into this issue, and normally I had ways to
work around it.

Basically I've got a bunch of PDF screen captures I've taken of a
website.  I need to have them as vector / PDF because I'll be zooming
in and out a lot, and the text needs to remain crisp and clear.

I've saved these PDFs using the Print >save as PDF function in Google Chrome.

The PDFs look fine and they do the job I need them to in AE, but my
problem comes in when I move and animate them around.  The text seems
to stumble around in place a few pixels... that's the best way I can
put it.. as if they don't have a completely defined position and each
frame does a little math equation to figure out it's location,
resulting in the jittering of each letter when close up and moving
slowly across words, etc. Sometimes the comp will render 2 frames and
then the stumble in position will happen, then 3 more frames then
another stumble in position.. it's only a pixel or two difference, but
when every single letter is doing this, it looks horrible.

I know AE is not a master at using PDF files, but can anyone tell me
what may be able to alleviate this?  I tried bringing the PDF into
Illustrator, but it's missing fonts and the layout looks different
than how the PDF looks when opened in a PDF Reader or AE.

Since I'm working with a lot of these, and I won't know exactly how
close I may need to get to each of the source files, it would be hard
to rasterize each one in Photoshop ahead of time and have the right
resolution available for AE when I'm building out my animation..

Any suggestions?
