how to deinterlace and restore this anime dvds framerate?

[mmbwdpnz]

its a PAL source. originally ntsc at 23.976 framerate.

[jagabo]

It was converted from 23.976 fps (maybe 24) to 25 fps by duplicating one frame out of every 24. Then it was captured with the wrong field order so the fields are out of phase.

TFM()
TDecimate(mode=2, rate=23.976)

[mmbwdpnz]

thank you !

Doesn't look interlaced to me (MediaInfo and others say it's PAL 25fps progressive). But on SeparateFields with TFF, motion is back and forth. I see cycles of 2 fields duplicated, as with telecine (or maybe it's just really late here).

So, how would one get back to normal, and what would TFM/Decimate do with the wrong field order?

So would what jajabo gave me work at correctly fixing this footage

Yes, although I'd do it slightly differently:

TFM()
TDecimate(Mode=1,Cycle=25,CycleR=1)

Doesn't look interlaced to me (MediaInfo and others say it's PAL 25fps progressive).

Yes, encoding it as progressive was a major screwup. But it's heavily interlaced. Look at it with something that doesn't deinterlace it, like an AviSynth script with no filtering applied and then opened in VDub. As jagabo said, it was converted by adding a duplicate frame a second, in the form of adding a duplicate field every half-second. So in every second there's half a second of continuous interlacing when there's steady movement. Follow the moon beginning at about the 13th second.

Right, the moon motion is what I was watching, then later with figures moving. Those frames told me that this was interlaced + added fields + field order error + encoded as progressive. Very creative.

Frames are encoded progressive but with 2:2:2:2:2:2:2:2:2:2:2:3 pulldown flags. So they come out of the encoder interlaced.

what would TFM/Decimate do with the wrong field order?

TFM() works for both TFF and BFF, as long as the field order is flagged correctly.

This might be a case where Ignore Pulldown Flags in DgIndex will work. Then just

Mpeg2Source("sample.d2v")
AssumeFPS(24) # or 23.976

But if parts of the video are different that may fail.

<edit>
Yes, different parts of the video are encoded differently. I just tried Ignore Pulldown Flags and it results in A/V sync errors. Also, if you use Mpg2Cut2 to mark and save small sections you'll see different encodings. Use the scripts I or manono posted.

i just wanted to know what you guys think of my final encode. Im not sure if I resized it correctly.

[manono]

Frames are encoded progressive but with 2:2:2:2:2:2:2:2:2:2:2:3 pulldown flags. So they come out of the encoder interlaced.

Which means I was wrong. I should have known when I saw it being 83% video in DGindex that there was pulldown involved. It just didn't click when I saw that. I apologize to you, sanlyn, as it really is progressive (with pulldown) and encoding it as progressive wasn't a mistake at all. I have never seen a retail DVD encoded this way. It shows other signs of having been 'home-made' too. mmbwdpnz, is this really a retail DVD or did you download it from somewhere?

[mmbwdpnz]

I bought it off amazon. It's from Italy and yes its from a retail dvd. Its better quality then the Japanese dvds it just has a few motion problems with the framerate.

If you had just run the scripts you'd be done by now and could compare the results.
