  • PSD vs AE resolutions in close-up shots

    Hi all, I am new here so thanks for having me!

    <font face=”inherit”>I am new to AE and got a bit confused with PSD vs AE resolutions, despite trying to find my way in </font>tutorials<font face=”inherit”> around the web.</font>

    I am working with raster images that are scanned to photoshop (pencil drawings). I scan them as a 600 dpi PNG file.
    Then, I import them to Photoshop to work on them. The PSD file is 300 PPI, and when I zoom in on my photoshop screen – all is sharp and crispy.
    Then, I import it to my AE composition, which is 1920×1080 as seen here in the attached image.

    In my animation, I want to zoom in to an object. I am NOT interested in animating the zoom motion. Just to show a piece of it magnified in the following frame (think about stop-motion as a reference).
    So I duplicate my layer and scale the new layer to the point that the object is magnified (200% in).
    But I can’t, it is all pixelated and blurry.
    What I am I doing wrong?
    These are pencil drawings that I create and scan, I have full controll on the image quality. Where am I losing resolution?
    Thank you!

    Check that the anchorpoint- and position- values are both on whole numbers, expecially if your exported assets may have an odd-number of pixels in their dimensions

    For example, if you have a layer thats 1001×1001 pixels, it’s default anchorpoint will be at theat layer’s centre: 500.5, 500.5, if you now position that layer at 960,540 every pixel is actually shifted half a pixel and needs to be anti-aliased.

    you’d either need to shift the anchorpoint or the position by 0.5 pixels

    That being said, scaling an asset to 200% will always need interpolation and ant-aliasing.

    You’d want to scale in after effects from 50% normal to 100% zoomed in, so a fullscreen asset you want to zoom into x2 will need to be 3840*2160 pixels at least.

    AE doesn’t really care for DPI. It only cares for the actual pixel by pixel information and the usual DPI setting for monitor display use is 72. So what would be the actual resolution if you change your image to 72 DPI?

    regardless of the DPI of your source image, the AE project res is only 1920 X1080. At that res, it’ll never be as sharp as you like. You AE comp size needs to be much higher.
