The downside of shape layers (and type layers) is that sometimes you need to disable continually rasterize and there's no way to do so.

Hi Roei

Look at this zoomed in view of an AI vector file both as a continious rasterized footage layer and converted to a native AE Shape Layer, many times better antialiasing that is very obvious at shallow angles, but also in slow animation

Thanks for the tips R.K and all. I noticed the jittering with fonts but not so much with vector illustrations... and especially with small movements. Robert, do you have more information resources about the 4 stages of antialiasing?

The continuous rasterize uses the old illustrator antialiasing that is quite bad for animation, it only has somehthing like 4 steps of graduations in antialiased values. 

You can see it by having some lines in an illustrator file that is near but not exactly horisontal or vertical.

Converting the illustrator to an AE shape layer and you will get much smoother antialiasing, but ofcourse that is not always possible if the illstrator file is a bit more complex and uses gradients or some of the newer functions of illustrator.

Shape layers if set to a 3d also have some issues with shimmering with small slow movement, and here the solution is either as you suggest, force it to be a raster layer by precomping it without using continious rasterize on that precomp, or if you need to keep the shape layer in the 3d comp, use the CC Force Motion Blur effect with a very high Shutter Angle so the shimmering will be smoothed out.

One thing I've noticed over the years is, if I take illustrator artwork and set it to continuously rasterise.  if I do any movement on it I will get a jitter on the edges.

to solve this.  I set it the layer to continuously raster.  scale it up way bigger than I'll ever need it.  precomp it and scale down the precomped layer to the size you want and do the move on that and you will end the jitters.

I know it wasn't exactly what you asked, but it's something that drove me nuts for years.

Subject: [AE] a question to illustrator users on AE

1. do you use the HDTV presets to avoid cropping? (if the layer is also outside of the canvas size) or do you just add another artboard that's a little bigger? 

2. have you found that the size of the second artboard in the HTDV preset of 14400x14400 makes a difference if it's that exact size that's created when you choose the preset? or do you just make your own second artboard? considering the fact that the second artboard in the HDTV preset is placed on half pixel and requires fixing everytime to avoid resampling of layers and antialiasing...

the Meyers (Hi there if you are tuning in... ) in their tutorial here explain the issue: https://www.lynda.com/After-Effects-tutorials/Illustrator-artboards/372438/497652-4.html, but they also mention that the 2nd artboard 14400x14400 is a "magic size" is essential. "The second artboard must be this size to trigger After Effects into not cropping off layers." I have not found it to be the case in my Ae versions since CS6.
