Resize Filter

If you are resizing your videos, Dr. DivX gives you several resizing filters to choose from. It turns out that resizing a digital picture can be accomplished many different ways. For example, to cut a picture in half, you could just remove every other pixel. That's actually a rather crude technique and the results are very satisfying. What you'd rather do is take some kind of average between neighboring pixels and use that instead. Lots of mathematicians like Cornelius Lanczos spend countless hours trying to find a better way to resize pictures. Each algorithm has different tradeoffs between things like quality and encoding speed. You can try some experiments to find your favorite, or just settle for default option.
