Hello,

i have following problem, so maybe you can help me:

In my Composition (SD) is a PSD-Layer. I`d like to increase the Layers Size, but don`t want that this layer gets "blured".

I use transparency and i want that this layer always shows hard Pixels and hard edges.

Hope, you understand.

Is there an option to keep the layers hardness fixed, even when i "zoom" in?

Sorry, no. This is why the Good Lord made Adobe illustrator. AE can keep the edges of vector files clean, but not bitmap files like Photoshop. And you can't put a bitmapped file into Illustrator and turn it into vector art: it has to be created as vector art from the very beginning.

Ok, thank you for your comment.

Hope, you all understand my problem.

My problem is not that it is impossible to zoom into bitmaps without loss of quality.

I know the difference between "pixel-orientated" an "vectorized" files.

Right: you want to keep the edges of the bitmapped files sharp. I recall that you wrote, " i want that this layer always shows hard Pixels and hard edges."

You can't do that with a bitmapped file in AE. You have to use a vector file for that.

I'm still not sure that I understand what you're asking for, but it may be that setting the layer to Draft mode will do what you're after. (See "Layer image quality".) My reading of the original question was that it was about preventing anti-aliasing. Sorry if I misread this.

YES!!

Sorry for this confusion. My english is not that best, but you understood me very well.

You solved my problem!

First it didn`t work.. because i wanted this effect only for one layer, i had to set the quality in the rendersettings in the exportdialog to "actual settings". ;)

Thanks so much!!

Hey mate,

I've discovered an easy way to get bitmaps etc to not anti-alias, while still giving you the ability to render at best quality.

Open up Illustrator, drop a bitmap into it, save it as an Adobe Illustrator file.

Put that Adobe Illustrator file into an After Effects, enable continuous rasterising, and even though it's a bitmap, AE treats it like a vector!!

Hope that works as well for you as it did for me... Now I can get that awesome retro bitmap look and combine it with some lighting and 2.5D :)

As far as I know, Illustrator does NOT do any magic transformations that turn bitmapped images into vector images.

As a test, get a VERY SMALL bitmapped image -- 120x120 or so -- in an Illustrator document, import the document into AE, and scale it up A LOT. If your assertion is correct, it should look just fine.

My money says it'll look lousy.

It does not "Magically turn it into a vector"

- When you scale up that small .ai file, it merely *treats* it like a vector file, i.e. does not try to anti-alias it. This is not a treatment which suddenly creates resolution where there is none, this is a treatment which when you scale up a bitmap will give you large, sharp squares for each bit as opposed to those terrible AE anti-aliased blurs.

This treatment carries on through to the render stage at full quality renders, very useful for making 8-bit animated characters, even in 2.5D with lights affecting the layers.

Just give it a go, my money has already been put on the table and I don't bluff.

You can also make a 'hires lores' image by increasing the .psd's resolution by multiplying it with an integer (2x, 3x, 4x, 8x) without interpolation ('nearest neighbour'). In that way, AE threat it as hires, but you keep the lo-res look.
