Graphics Compression
on Jul 26, 2006 at 2:52:42 pm

The DVD I am currently authoring involves a number of motion menus with sometimes spindly animations, very small/thin text and finally, hard edged graphics set on diagonal lines. When the designer created these in AE they looked beautiful (obviously) but we all know that when you get into the NTSC world things change.

I've convinced them to drop the spindly animations, but the 1-2 pixel thin text looses a lot of quality (I'm talking whole sections of the characters) and the hard edged diagonal lines suffer noticeably as well on the final DVD.

I was wondering if there are any particular tricks to use when compressing graphics, such as the ones I listed above, for use in DVD Studio Pro.

Thanks,

Dillon

No tricks really except to always be sure to use lines and pixel values divisable of at least 2, with the minimum recommended size for NTSC being 4 pixels. Pretty much the same as for editing NTSC for broadcast.

On the really thin lines, do a vertical blur to spread them out over a couple of scan lines.
Don't do a horizontal blur, it's not necessary.
