DivX 6.2.5 Codec

Posted by Mark Nelson on 15th June 2006 | Permanent Link

Video compression upstart DivX has just released version 6.25 of their free Windows codec. They claim a new feature that “sharpens” DivX videos. I’ll have to see it to understand it, much less believe it.

As is true with every release from these guys, we are promised super performance enhancements, meaning you can create videos faster than ever, even on mortal CPUs, like the one I’m typing on now.

    btw, Crystalplayer’s had a sharpening feature for quite some time now, and it’s adjustable.
