Re: Re-size or crop? (was: quality question)

Logan,

I think you're always safest to crop, but it depends on the tool you're using to do the resizing. For instance, if I forget to resize from 720x540 in PS to 720x480, then import the still, the MPEG still encoder does a pretty crummy job of scaling, and it is noticeable. But if I do it in PS, no problem. AE has good scaling algorithms. I usually just use the CMD-opt-F to do the fit to fill on a DV sized comp (720x480) if I have any D1 footage (720x486). I know there is always the chance of a little degradation, but I haven't seen anything to scare me away yet.


cheers,
bk

Ok... I'm curious about this one.

When designing we use square pixels at 720x540 and re-size to 720x486 for
broadcast. All the graphics I create get resized either to 720x486 or to
720x480 from square source. Encoding/re-sizing video should follow the
same logic. You would think that going from D1 720x486 to 720x480 for DVD
you should resize.

I know... it's only 6 pixels.

Resize or crop?


all the best,
Logan Kelsey
