Is colorspace YV12? DirectShowSource("F:\DVCodecs\Analysis\Ced_dv.avi").ConvertToYV12(interlaced=***)

Perhaps ffdshow has blacklisted the encoder you use, but not the program you preview the script with?

hi guys thanks for your help I now (finally) found how to do: DirectshowSource("1.grf", fps=25, framecount=133340, audio=false) Graphstudio really helps, i just did not know how to make the grf file(forgot to remove the video renderer) and that i had to keep infos like fps and framecount greetings user
