Deinterlacing a Cartoon

[nel-son]

Hi,

i've some Videos here i want to deinterlace. after bobbing the source i've got this notation for one second of the video:

a a a a b b b b c c c c c c d d d d e e e e f e f f f f g g g g h h h h h h i i i i j j j j k j k k k k l l l l m m m m m m n n n n

the green frames belong to the next second. as you can see the video jumps back after the firs f-frame to the e-frame and then again to the f-frame. the same with j and k. with other cartoons i've got very good results with

tfm().tecimate(23.976)

any idea how to deinterlace this video?

here is a sample: http://www20.zippyshare.com/v/RYjeCbKu/file.html

the posted sample is 4:2:2:2:2 with no frame jumps. the sample doesn't have a single interlanced frame all frames are PsF.

so the source is 25 FPS.

[nel-son]

wrong sample, sorry. here is the right one: http://www120.zippyshare.com/v/yQeMlGzc/file.html

ok the file is repeating interlanced frames as frames and not the fields.

and DXVA deinterlancer don't like this.

removing the repeated frames first and than field matching should do the trick.

i don't know how to this sorry.

[nel-son]

a simple

tfm().decimate()

looks very good. after that the framerate is 23.976.

Seems a Disney's cartoon, then must be of 29.970 fps.
A trick: Japanese video (anime) -> Film (23.976 fps)
North American cartoon -> NTSC (29.970 fps)
European cartoon -> probably PAL (25.000 fps)

EDIT: try this:

mmm no
usually disney's are 23.976fps too (at least the old ones)
and usa/european are 15 or 18 fps, like this

[huhn]

it depends on what is used to as a source.

the first sample is created from 25 FPs the second samples is technically broken.

there are repeated frames with 2 different fields like this: abab

Indeed, the old Disney movies are 23.976, but in this case (I clarify now) is video made exlusively for TV (NTSC).

I thought 24fps was still the standard, just as it is for "NTSC" TV dramas.

[huhn]

the problem here is that the standard was ignored.

What complicates analysis is that this video was not made intended for the cinema, such as " The Jungle Book 2 " .
If it looks good with IVTC then nothing more add.

Given that cartoons use duplicate frames for still scenes I would look for some high motion section (such as rolling end credits). Also, you might be wise to use a free decimator like TDecimate(mode=2, frate=24/1.001).

The sample originates from VHS. The repeats are inserted frames resulting from a poor capture.

The way to fix this is to go back to "your" source and capture it properly.
