Chroma delay ?

I have this video

Every 4 frames seems that the chroma is delayed by one frame or swaped with the next field

frame 43:
with
TFM(Mode=5, pp=0, slow=2, mChroma=false)

with

Quote:

flds = SeparateFields()
StackVertical(flds.SelectEven(),flds.SelectOdd() )

both fields have a chroma problem, now the same, after a

Quote:

clip2=trim(1,0)
mergechroma(last,clip2,1.0)

Notice that the bottom field is Ok, but not the top
Has anyone deal with this pattern ? Any advise how to deal with this ?

it has been encoded progressively.

So the chroma between both fields of a frame has been blended together.

There might be a way to undo this... but I never tried it.

Can you give me a tip ?
or some script posted here that handles some similar issues and I'll make some tests
That is if you think that a script can handle this and not a C++ plugin

My first though is that I need something similar with what TFM does, but instead of field matching, it should match luma and chroma planes

I don't know how to start and I have seen this issue to several cartoons
