Graphic display question

Why does AE display solids etc like this, is there a way to get a clean solid edge instead of the kind of transparent edges?

Thanks

That happens because you either have a layer scaled up way beyond 100% or you have a 3D camera too close to a layer. Or both, perhaps.

AE can only work with the image pixels it has available to it. If you scale too much or get a camera too close, it makes those image pixels much bigger than they really are.

AE's doing it's best, but you're just not using it properly.

I get whats happening now. When I select points on the solid layer I didn't realise it was increasing the scale value opposed to cropping or expanding the actual layer size.

So I assume it is always best practice to make any solid layer the comp size and resize down from that resolution?

I made a solid the comp size and and down sized/scaled and still get those kind of transparent edges

If a layer is positioned so that its edge doesn't exactly align with the boundaries of the pixel grid, then After Effects uses antialiasing along that edge. This makes animation appear smooth when a layer moves. If you don't want this subpixel interpolation, then you can turn it off for a layer by switching it to Draft mode.

Much more detail is in After Effects Help, here:
"Layer image quality and subpixel positioning"

I'm on the right track now!

Thanks!!

Marc

This also happens when you have a Comp with a very small resolution and you are viewing it with a Wrong Zoom Percentage.
