"Avisynth open failure"

[Firra]

Hey im trying to decode an avi clip from vegas into xVid, but when i open my avs file with vdub i get this message.

AVISYNTH open failure:
AVISOURCE: the video decompressor couldnt produce YUY2 or RGB output

(C:\USERS\FREDRIK\XVID\DUCKINTRO.avs,line 1)

my avs script is

AVISource("DUCK.avi")
Crop(0,0,-0,-0)
ConvertToYV12()

when i try to open the avi instead i get:
The decompression codec cannot decompress to an rgb format. This is very unusual. Check that any "Force YUY2" options are not enabled in the codecs properties

What could be the problem?

Also when i render from sony vegas a 4 minute clip is about 150-170 gb big, could that be part of the solution?

Would really appreciate some help, its frigging me off

What's codec used in this video file?
What's codec used as decompressor?

Try DirectShowSource instead AVISource.

BTW im really bad at these things :D so if you could give me some guiding on your answers so i know what to do :D

Remind, what codec You use when export wideo in Vegas?

Use GSpot or MediaInfo.

Open video file in VirtualDub and look at File Information option (what's used decompressor).

I didnt compress the file when i rendered from sony vegas so it should be uncompressed if thats what you wonder :D

As advised, get Gspot (freeware)

Drag & drop your AVI file (DUCK.AVI) onto it and post the screenshot here.

OT: Uncompressed? 1 minute = 37.5GB-42.5GB ???

[Firra]

Yes :S when i render clip from virtual dub uncompressed they can be everything from 1gb to 13 gb.

the 1b clip is about 5-7 secs :D

But im rendering the clips into xvid and then rendering from vegas. Ill see if that has an effect

SFDB? I'm never hear about this FourCC and can't find any info.

I'm not have Soney Vegas, well can't help more.

I'm propose - back to Sony Vegas and check export settings.
