I'm trying to open video files in AviSynth and fail so far.

My goal is to deinterlace lossless video files (768x576 pixel, though VirtualDub reports them as 720x576) into 50fps videos playable on a computer. No DVD or Bluray compatibilty needed, but if possible it's welcome.

I'm on a Mac with OSX 10.6.8 and have installed AviSynth 2.6 and VirtualDub 1.10.4 with AMVPack_160625 (thru PlayOnMac). Additionally I installed the QTGMC 32bit plugins. I tried VirtualDub 1.10.5test7 and 1.09.11 with no difference.

I can open the videos in VirtualDub with no problem, but I can't do that via an avs script (I wrote: AVISource("test.avi") ) The file test.avi is in the plugins folder.
I always get the message "AVISource autodetect: couldn't open file" or AVIFileSource: couldn't open file" when trying it with AviSource, and "the manager won't talk to me" when trying DirectShowSource. With TDeint ( TDeint(AVISource("test.avi")) I get "couldn't locate decompressor for fourcc dvsd"

I tried other files, like mpeg2 and H264 and dv and I always get the same error messages.

I'm trying to read through posts in different forums and faqs, but as I'm in a special situation with my mac, it's difficult to determine which solutions apply to my case.

So, I'm at a loss here. Could someone point me into the right direction what to do to open files with AviSynth? Is there something essentially missing in my installation?

Thanks for listening...

I just looked up PlayOnMac and it mentions playing games. For Avisynth to work, it would need to emulate the full Video for Windows environment. You may want to try Vapoursynth instead.

Thanks for your input. I was going with two instructions how to install AviSynth on a mac:

http://avisynth.nl/index.php/HOWTO:_AviSynth_video_processing_with_WINE

http://www.animemusicvideos.org/forum/viewtopic.php?f=44&t=125120#p1546742

However, when I started the installation again from scratch, I noticed that some parts seem to not install. So I guess this might be a wine related problem, I'll have to check that.

VapourSynth looks pretty interesting, especially since it's directly usable from the command line, but I couldn't verify that I can do this 50fps deinterlace with VapourSynth. Do you know about that?

oh, and the title isn't entirely correct: I could open .avs in VirtualDub, just not with AviSource as input. "Version()" works as expected.

QTGMC was ported to VapourSynth. I've never used VS, personally. I think Doom9 would be the place to go for more info on that.
