I'm trying to write very simple Logo YUV12 resp. YUY2 plugin for Avisynth 2,5 with very simple alpha masking. But first version with only XY bluring was very slow, and even the test version of Plugin with only memcpy (srcp,dstp,sizeof) is slower then using Delogo in Vdub??. I don't understand why?? So I'm not sure if i'll continue in this work.
