Best deinterlace filter?

[BluDChyLD]

I've been encoding a lot of old black and white movies recently and they all seem to be interlaced material. I've been using the "field deinterlace" filter bundled with gknot, it does the job but the ghost effect can be annoying at times. Are there any other deinterlace filters that are better?
Thanks,

I've been using the new DECOMB set of filters. I used TELECIDE(GUIDE=1) with DECIMATE() last night to IVTC a black and white telecined movie. The result was better than I could have hoped for - so far, I haven't found an interlaced frame that it missed (kudos to Donald for this effort!). It was also relatively fast (it ran at 1.1 real time in CCE).

There is no ghosting at all with this filter set.

Try setting blend=false with FieldDeinterlace to eliminate the ghosting.

But if it's a movie, you probably want IVTC, rather than simple deinterlacing.

I have had wonderfull results with "GreedyHMA".Just read the readme for parameters.

the source matierial is all PAL so I don't need IVTC, I'll try field deinterlace without the blend option.

If it's a PAL *movie*, you may still need/want Telecide without Decimate to properly align the fields.

GreedyHMA can DeInterlace and IVTC.To quote the GreedyHMA readme.

"0 - No pulldown, just do pure deinterlace (Force Video). Doesn't drop any frames so FPS is left at 30 FPS, or wherever. Doesn't decimate(pentimate?). Use if you have (and want) 30 fps video source ormaybe 25 FPS PAL video.

Try GreedyHMA(0,0,0,0,0,0,0,0).

How about the "pure interlaced" ntsc 29.97 fps material,
any idea ? I think it's the most difficult part, I never
get satisfied result. Please give your idea.

Thank you.

i think pure interlaced is the same wether its PAL or NTSC.
tomsMoComp gives good results but it is a bit slow. sometimes i use bob() and selecteven() instead. i don't like anything with blend.
i'll test smoothdeinterlacer too soon.

tomsMoComp gives good results but it is a bit slow.

Does your machine have ssemmx support? At least a P3?

In DScaler TomsMoComp can easily give 60 fps with SearchEffort=3 on my 866 Mhz P3.

The speed is excellent for me, not sure what kind of system you have but it's very impressive on my system considering the processing the filter is doing.

I've been meaning to do that but there is always something else and using scripts like yours will get the job done, just a bit slower.

But it's on my list.

@Tom
yes i have p3. i use the default search effort of 15. it is normal it is a little slower than simpler methods but it always gives great results. i'll test again with lower search effort. good luck in the yv12 version.
