Hi,
I have a problem with deinterlaced filters (A ghosting problem). When there's an scene change, the deinterlaced filter sometimes mix both images. In one frame, you see a ghost of the next scene, then you get to see the scene as it normally would be in the next frame, after that the image change happens. What can I do to stop watching parts of the next scene where it doesn't has to show?

I make test with three deinterlaced filter. (I used these filters guided by meGUI.) I upload any images with this problem. Each sequence of images has 4 frames with different deinterlaced filter:
-The first image had not deinterlaced filter.
-The second image use the next (And load subtitules):
edeintted = AssumeTFF().SeparateFields().SelectEven().EEDI2(field=-1)
tdeintted = TDeint(edeint=edeintted,order=1)
tfm(order=1,clip2=tdeintted).tdecimate(hybrid=3)
-The third image use the next (TIVTC):
tfm(order=1).tdecimate(hybrid=3)
-The second image use the next (Decomb IVTC):
AssumeTFF().Telecide(guide=1).Decimate(mode=1,threshold=2.0)

The sequence of images "frame1" is perfect. (Each image is about 250KB)

The sequence "frame2" had a ghost at second and third frame. (Red circle). The image with (Decomb IVTC) filter is perfect.

The sequence "frame3" had not ghost at second and third frame (The previous frame, YES, wierd). The image with (Decomb IVTC) filter mix both scenes and It is the worst.

At the new sequence, the scene change, all the images are perfect.
The sequence "frame4" is OK, is the change of scene.

Now another change of scenes. The filters are the same:
The sequence of images "frame5" is perfect.

The sequence "frame6" had a mix of the scenes at second and third frame. The image with (Decomb IVTC) filter is perfect.

The sequence "frame7" is OK, is the change of scene.

Sorry, for my poor english.

Provide a sample of unprocessed source or it'll be difficult to help you. My first inclination is that the field order is wrong or a bad field transition occured, but it's impossible to reproduce and fix without a source. You can make one in dgindex or chopperxp.
