Opening Avisynth script on virtualDub - Error Message

[HugoBraule]

Hi,
I'm new around. Would like that you tell me what is wrong in the script below, if you will. A message comes and reads: "Avisynth open failure: AVI Source: couldn't locate a decompressor four fourcc (F:\aviSynh 2.5\sidebyside.avs, line 12)

Width=720
Height=480
BorderColour=$000000 # White would be set to $FFFFFF
BorderWidth=0 # Set to 0 if no border required

clip1="cena4e.avi" # This provides the audio track. It also sets the duration of all other videos by looping or trimming their length !
clip2="cena4f.avi"

bw=BorderWidth
w=720
h=480
clip1=AVISource("cena4e.avi").BilinearResize(w,h). Letterbox(bw,bw,bw,bw, BorderColour)
totalframes=Framecount(clip1)
clip2=AVISource("cena4f.avi").BilinearResize(w,h). Letterbox(bw,bw,bw,bw, BorderColour)
StackHorizontal(clip1,clip2)

I have ffdshow video codec, Huffiuv v.2.1.1 and some others. It used to work before. Now I've made some changes to the original script trying to figure something. Nothing works.

The former one looks lyke this:

Width=720
Height=480
BorderColour=$000000 # White would be set to $FFFFFF
BorderWidth=0 # Set to 0 if no border required

a1="01.avi" # This provides the audio track. It also sets the duration of all other videos by looping or trimming their length !
a2="02.avi"

bw=BorderWidth
w=720
h=480
a1=AVISource( a1,).BilinearResize(w,h).Letterbox(bw,bw,bw,bw, BorderColour)
totalframes=Framecount(a1)
a2=AVISource( a2 ).BilinearResize(w,h).Letterbox(bw,bw,bw,bw, BorderColour)
StackHorizontal(a1,a2)


I will appreciate any help. I have a clip to put on the air but I can't.

thanks,

Hugo Braule

This is telling you you do not have the necessary VfW codec for your source file cena4e.avi.

Use GSpot or MediaInfo to determine which codec is used in the source.
If it is one supported by ffdshow, you can enable it in the ffdshow VfW configuration.

Hi,

I wish to thank you for your help. I finally understood that I can't open a codec from outside C:\. It's running. Thank you very much, Gavino.
