Is there anything that would get rid of this,it happens during some scene changes but not all,but it happens frequently enough that it is an issue,so any help or advice would be greatly appreciated.

Thanks

Now if I can just figure this out we can get this thing done already.

What's the color space of the source video? - RGB24, YUY2, YV12?  Also, what filters are you using to filter the chroma channel?

I've seen something like this before when I was doing the Japanese laserdisc transfer for The Evil Dead. I can't remember exactly what caused it, but I think it was something to do with colourspace conversions and IVTC.

What does you script look like again?

I had a similar problem too.  I was using filters that required YV12 input, but the source was interlaced.  When interlaced video is converted to the Windows version of YV12, it screws up the color because one line of color information covers two lines of the resolution.  The fix was to use ConverttoYV12(interlaced=true) in the avisynth script.  However, from the screen shots, it looks like the interlaced chroma channel doesn't have this YV12 interlaced problem.  But the problem I had was very similar - chroma was becoming misaligned and being dragged into other shots at scene changes.

the source file is DV Type2,but the sample is YUY2(above screens),and there is no script yet,I am not sure how to approach this,shouldn't I get rid of this first and then move from there?

but thanks for taking the time and checking it over,this is my only hold up at the moment.

 

*also if you know VDub errors please look at that thread to that I started,I NEED to know what that means and how to prevent it from happening.

Thanks again

Are you using Cedocida to decode the DV? If so, what option have you selected for the YV12 subsampling? (I think AviSynth assumes MPEG2 interlaced subsampling.)

Yes I am using that Cedocida codec you sent me in PM,but how do I check what option I selected for the YV12 subsampling?

But if you mean when I open my source avi's and save my samples I am saving them with Lagarith (YUY2).

In VDub, select Video -> Compression, choose Cedocida, then click on 'Configure'.
