Avisynth Deinterlace Help

[pureimpure]

I can't tell if this is a Bad Pal (25)to NTSC(29.97) conversion (interlaced).
Or some funky Film Hybrid,

AutoGK says the clip is FILM.
But playback seems jerky and when using Assumefps (25) I get blended frames.

Can someone please help and post their script so I can figure this out.

Thanks in advance.

It looks like normal pulldown to me. DGIndex with honor flags

MPEG2Source("VTS_01_1.d2v")
TFM()
TDecimate()

I'll try it, but does that panning scene look any different.
Thanks for your help

It still looks jumpy to me.
Good job getting rid of the interlacing though.

poisondeathray is correct; it just needs a standard IVTC.

...and when using Assumefps (25) I get blended frames

No, you don't - not if applying it after an IVTC. Maybe you're thinking of ConvertFPS(25). AssumeFPS(25) just speeds it up.

There's still some issues using this script.
I noticed playing it back with virtualdub that the frame rate seemed fine.
I'm importing this into Tmpgenc and it plays back jumpy.
That's not the real problem I can use something else to re-encode it.

Try using that script using this sample here.
It gets all jagged and crazy during this scene.

(FILE is SAMPLE.VOB)

Looks like the same sample.

[pureimpure]

It's Sample.vob.

That's the part that gets crazy witht he script used above.
ANy idea what else would work so it doesn't get like that.

When I click on the link I get offerred the same VTS_01_1.VOB.

Are you talking about previewing within those programs? Don't count on previewing to play smoothly in any editor. Editors are generally not designed as media players. And when filtering like this the CPU may not always be able to deliver the frames fast enough to get smooth playback. All that matters is how the finished product plays.

TFM().TDecimate() delivered smooth results with both VirtualDub and TMPGEnc Plus (23.976 fps with pulldown flags). Why the talk of 25 fps? Are you making a PAL DVD for some reason?

Stupid Mediafire.


Here's Sample.vob (correct link)

I thought maybe it was a PAL to NTSC conversion.

Are you talking about the moire artifacts in the windows? Unfortunately, TFM() has problems with that type of source. A manual IVTC will work:

MPEG2Source("sample.d2v")
AssumeTFF()
SeparateFields()
SelectEvery(10, 0,1, 2,3,5,6,8,9)
Weave()

xvid.avi

That probably won't work over the entire movie because there are likely to be breaks in the telecine pattern now and then.

The problem is mostly (but not entirely) that those thin horizontal lines of the blinds are seen as residual interlacing by TFM, and the deinterlacer kicks in. It'll do a much better job (but still not perfect) by either raising the CThresh or (better) turning off the postprocessor:

TFM(PP=0)
TDecimate()

Interestingly, Decomb does a much better (and nearly perfect) job on that passage, also with the postprocessor turned off:

AssumeTFF()
Telecide(Guide=1,Post=0)
Decimate()

Or, you can leave the postprocessor on but tweak the VThresh so it's not as sensitive. Raising it to 70 from the default 50 seems to do the trick:

AssumeTFF()
Telecide(Guide=1,VThresh=70)
Decimate()
