PSD scaling and movement
on Nov 15, 2013 at 4:40:32 pm


Im working with a film where the customer want their product (PSD-file) scaled all over the screen while it is moving.
Is is not so charming seeing PSD-files move ultra close, its harsh and sharp. Any suggestions? Any way to treat the image to appear more like a "moving image / film".

Yes: work with HUGE PSD's.

For example, if you want to work in a 1920x1080 comp,and you want to show the upper-right quarter of a 16x9 image, the PSD image needs to be at LEAST 3800 pixels wide and 2160 pixels high. You can then scale such an image to 100% and lose no image resolution.

Photoshop's DPI is irrelevant: only the pixels count in AE. If the client decides to simply scale up existing low-resolution images to fit in a larger, higher-resolution Photoshop document, the client gains nothing. The existing pixels in the lower-resolution layer have simply been made larger. These is NO improvement in image resolution.

If you can't work with big images, you will lose image resolution when scaled beyond 100%. Some of the more recent versions of After Effects can help the scaling issue a LITTLE, but they can't work miracles.

For your reference, After Effects can not work with bitmapped images that are more than 30,000 pixels in either dimension.

So if the client doesn't have high-resolution images, you're stuck.
