Resize QuickTime Player windows to 'smooth' sizes Apps
I searched the site but did not find previous mention of this, so here it is.

Holding the Option key down while dragging to resize a QuickTime window will give you the (and I'm not sure of the technical term here) "non-interpolated sizes" available for that resolution, much in the same way the Dock behaves when you Option-drag its divider.

Resize QuickTime Player windows to 'smooth' sizes

Cool, thanks for that, didn't know that was available, I can now do 50% larger when I could only do 100% (Double Size) from the View menu.

Resize QuickTime Player windows to non-proportional sizes

There's more: If you hold Shift while dragging, you are able to change to an non-proportional size. Good for resizing anamorph videos to square pixels. (You can see the actual and original size in the information panel.)

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 ...
