Ian, your suggestion works well enough for the one scene I've tried it on. Thanks for the tip. Also thanks for the work you are doing on avisynth!

I've just had a look at the source for the autolevels plugin. I know nothing about avisynth data structures and internals, but it assumes the pixel data is planar. Won't it just treat y,u,v as three luma values? So if the image is very dark, it will think there are a bunch of y=128 pixels after performing the GrayScale() conversion, won't it?

Overall, it seems wrong to say autolevels() supports anything but YV12 (except in special cases) right now.
