Remember that VFAPI upsamples to RGB by default in interlaced mode. If your script outputs progressive footage (e.g. you do IVTC with Telecide + Decimate), put "_P" just before the extension in the filename. This forces progressive upsampling. So for example bibleblack_P.avs.
Please ignore that. Apparently it only works when you're using .d2vs directly. AVS scripts are converted to RGB24 in progressive mode by default.
