VirtualDub framserve to Gordian Knot

[dimtim]

Ok so the issue is that I have some video that I edited in virtualDub and I frameserved it to Gordian Knot. I set up everything perfectly the only issue was that when I started encoding I got the error message:

Avisynth open failure:
UnDot: Supports YUY2 color format only

Yeah basically what I want to be able to do is take a video or dvd and edit it in virtualDub, framserve it to Gordian Knot, and then encode it to MPEG4.

Thanks a lot

Hi-

A couple of fixes come to mind:

1. Remove both the Undot.dll Loadplugin and Undot() lines from your GKnot generated AviSynth script.
2. Add ConvertToYV12() just before the Undot() line.

As near as I can tell, your error message isn't exactly correct, as Undot supports the YV12 colorspace. In any event, you're evidently feeding GKnot/VDubMod an AVI in a different colorspace, probably RGB32.

Hey thanks for the great tip and it worked. Now the only problem is the audio. Is there anyway to get Gordian Knot to accept audio from a virtualDub frameserve because the video works great.

Thanks

Hi-

No, GKnot won't extract and reencode audio inside of an AVI. You'll have to demux it from the video yourself and point GKnot to it if you want it reencoded.

As an alternative, you might try GKnot's little brother, AutoGK, which accepts AVI input, and will demux and reencode the audio for you. I'm not positive that you won't run into that same error message, but I don't think so.
