29.970 NTSC DVD use Deinterlacing result in Color deviation occurs

I have encoded some NTSC DVDs. I use TFM().Tdecimate() to deal with deinterlacing. Usually, I can get good results. But when I deal with a DVD, I use TFM().Tdecimate() results in incorrect color, as shown in the following figure:





Do anyone know the reason and how to deal with it, thank you

What source filter did you use ? Post your full script

Did you try TFM(chroma=true) ?

Maybe there are problems on this DVD, and someone might be able to give better suggestions if you post a video sample of the source

Yeah, that's not 'incorrect color' but chroma bleeding over from the previous or next frame. As pdr suggests (and something you should always do when asking this kind of question), post the complete script and a piece from the source. 10 seconds will be plenty, an M2V cut from the VOB using DGIndex.

Thank you very much. I have successfully solved this problem. Tfm(). Tdecimate() cannot be placed after crop(). After I adjust the order, it becomes normal
