Non interpolated sizes
Authored by: alblue on May 24, '05 04:22:43AM

This is a great feautre that I didn't know about ...

What non-interpolated means is that you don't get any scaling artifacts. If you have a movie at 100x100 pixels, for example, then if you shrink it down to (say) 81x81, then there's not a one-for-one map between the new pixel and the old pixel. So QuickTime has to put an imaginary 81x81 grid over the 100x100 pixels, and 'guess' what the pixels would be like in between (interpolation).

If on the other hand you resize it to 50x50 (or even increase to 200x200) then each pixel in the resized view is a whole number of pixels in the input. (In the case of shrinking it to 50x50, each pixel corresponds to 4 pixels in the bigger image, and it takes an average of these).

The net effect is that if you resize a movie with this feature, you'll see steps equivalent to the 'small', 'medium' and 'large' steps, and the image quality will be subtly better ...
