Looks like you forgot to choose lagarith

to
Lagarith Lossless AVI then

Codec ID : UYVY

Another option is debugmode frameserver (but you have to be careful with the way vegas handles levels)

[IanB]

For an .avi file with fourcc "UYVY", AviSource will first ask windows for a codec to decode UYVY to YV12. And if none are available next a codec to decode UYVY to YUY2, then RGB32 and RGB24. If they all fail you get the cannot find a codec message. You did not get that message so some codec put it's hand up and said "Yes I can do that." but after it was loaded and initialised and Avisynth asked for frame 0 to be decoded it reneged on the deal and said oops I cannot do that after all.

Quite a few codecs have this evil behaviour, the Panasonic DV codec is one example of being notorious for doing this for DV sources, it can actually only do RGB24 decoding. The solution there is to add Pixel_Type="RGB24". A better solution is to use a correctly working codec like Cedocide.

For your problem you can try adding AviSource(.... , Pixel_Type="YUY2") to your script, your installed bad UYVY decoder may actually be able to do that. If that fails you need to uninstall the broken codec and install a working UYVY codec. Or you could fix your work flow as above.

Many thank for this explanation !
This now saves me lots of headaches, because my UYVY intermediates
(which I only made to get off the faulty WinXP's DirectShow quartz.dll decodes from plain DV-AVI
were obviously decoded improperly again using AviSource which indeed seemed to have called WinXP's DirectShow quartz.dll again.
Booho.
