Title: Xvid 1.3.0 Final
Post by: IgorC on 2011-02-24 08:43:49
Xvid 1.3.0 Final
http://www.xvid.org/ (http://www.xvid.org/)

New Xvid 1.3 has a new multicore support. It's slice based but the loss in quality is nothing (<0.1%)
Now Xvid scales good with high number of cores and probably will completely load CPUs with 4-6 cores + HT as well.
