x264 CLI can't find AviSynth

[Robin]

My trouble is that I want to run x264 using its own CLI, but cannot get it to find my installation of AviSynth. Everytime I try I get a"avs [error]: failed to load avisynth" error. I've tried re-installing AviSynth 2.5.8 (tried installing 2.6 alpha too) and hunting down any old remnant of it that could be lurking somewhere on the harddrive, but no luck. The same thing happens both for opening avs scripts and avi files. My OS is Vista 64 bit.

This is very frustrating, any ideas on what could be wrong?

x264 must be the same bit-ness as your Avisynth.

This means x264 64-bit cannot call Avisynth 32-bit.  There is no way around this from within x264.

That was it, I was running 64-bit x264. Thank you very much for the very fast reply!

Any easy way to use x264 64-bit purely, without using pipe (or what ever they call it)? Thanks.

There is a 64-bit version of Avisynth.

You'd need 64-bit Avisynth and to only use plugins that have 64-bit versions. With Lord Mulders tool, you can use the 32-bit versions of everything with 64-bit x264.

I see, thanks for the info. What is the estimated speed gain if I use pure 64 bit?

It varies, but there is improvement. Download Lord Mulder's GUI and use it to benchmark a few short clips to get an idea.

Thanks for the reply.
