Loading Quicktime in Avisynth?

Can avisynth load up Quicktime files to run filters on? I've got a trailer I want to resize and convert over to play with, but it's a QT .mov file, and while Premiere should be able to do it, I thought I'd check and see if avisynth could do it first.

You can, but it requires a plugin. Check avisynth.org for the link.

OK- I got the plugin, and I've got avisynth opening the Quicktime. But, it's doing some seriously funky stuff in VirtualDub. I want to make a quick and dirty MJPEG version of the file to use for editing and then swap it out for a full-quality HuffYUV file for the final encode. But my 'quick and dirty' MJPEG file (for a 80 second trailer) took an hour and a half and is over 700 megs.

Looking at the info on the file in VirtualDub, it says that it is 600 FPS. So, I add the line 'AssumeFPS(30)' to my avisynth script. This did no good, it just lead to having a much slower (20 times slower...) video file (OK, so now I've learned exactly what AssumeFPS does...).

How do I get this to conver over nicely?

If it's duplicating frames (which is what it sounds like) then you are probably going to have to use the selectevery function to delete the frames you dont want.

It sounds like a really particular case though, so without being you I can't really help.
