YV12 is YUV. Think of "YUV" as the broader family. YV12 is a subset of YUV, specifically 4:2:0 planar. YV12 is required for BD

The only things to remember in avisynth are if your content is interlaced, you must use the interlaced=true switch, and the correct matrix (usually Rec709 for HD and 601 for SD) if coming from a non YUV source
