Thanks guys. I'm still having a problem though. I made a folder in my plugins directory for MaskTools and I'm calling it in my script like this:LoadPlugin("D:\Program Files\AviSynth 2.5\plugins\MaskTools\MaskTools.dll")When I load the script, it's saying "there is no function named yv12lutxy." Is there something else I need, like a newer version of AVIsynth? Report
