For pure interlaced, you might be better off with LeakKernelDeint() or TDeint() rather than FieldDeinterlace(). For field-shifted PAL, any competent field matcher, such as Telecide() or Tfm() will be fine. For 3:2 telecined, either Decomb or Tfm()/Tdecimate() will be good. For field-blended video, slit your wrists.

For PAL i use alparysoft deinterlace, but it's requiring payment.

nice to know i'm appreciated i do a lot of blending for R4 DVDs...

with a stubborn movie that was shot on NTSC DV (lots of high-contrast edges that come out stairsteppy no matter what) i just had a go at this one. it's twice as slow as TDeint:

repair(
\last.tdeint(1,1,type=2,mtnmode=3),
\last.tdeint(1,1,type=3,mtnmode=3),mode=1)

the line breaks are just for readibility. it'll work if you paste it into a script this way though.

the aim of this is to use edge direction, but repress the stray pixel artefacts by using a more conservative mode. it's quite experimental, but seems to give the best of both worlds.

you'll need Tritical's TDeint and Kassandro's Removegrain (search )

From me they won't get money, as long as our free tools are so much better.


@ Mug Funky: Nice idea! (But what about artefacts actually being about 2-pixel clusters?)

edit: Halt, had thought too short. type=2 won't even have those 'holes' , so repair(1) does it. Again: nice

actually, i think it needs some tweaking... it worked on the source at work, but not on my sample noisy TV cap at home - it just used the kernel mode the whole time. perhaps i've got type 2 and type 3 mixed up in repair?

Trust me you are appreciated.
While we're (loosly) on the subject:
Can someone recommend a method for getting rid of blends while still maintaining smoothness during pans/zooms. It might just me doing something wrong though. Only way I see is using 2 types of deinterlace, i.e. some deblend for normal scenes and just straight deinterlacing for pans/zooms.
BTW this is regarding pure interlaced field blended PAL footage.

If it really is "pure interlaced field blended PAL", you might find something in this thread.


@ Mug Funky: Uh, bad eyes today. Looking closer, you've indeed mixed up the two clips.
Should be Repair( [ela] , [kernel] , 1 )

I have tried leakkerneldeint(order=1) and when the avs is viewed in vdubmod, some sort of "ghosting" happens. I was using an anime DVD source and the "ghosting" only happens on the character outlines (the black lines around the drawing). Has anyone encountered this as well? What is the solution?

Thanks

DON'T DO THAT DIDEE!!

Tritical might find out and start charging us $$.

You wouldn't happen to have some screenshots of this?

np: The Orb - 73.5 ft. nitraM (Orb Sessions Volume 1)

I checked the field order using a program called "bitrate". this app was used before in one of the doom9's guides.

How do I know if the frame is a blended field? maybe you can point me to a URL?
thank you

Any thoughts on Tdeint versus LeakKernelDeint/Bob for fully interlaced NTSC DV footage? I just finally threw out DGBob for Leak (nice job Leak!), but I'm not sure if I should try to tackle the big Tdeint...

I'm in kind of a weird situation of having footage involving fast-moving thin string which might be stepped through frame by frame by someone. I've basically been sticking with a threshold of 0 because of that (and not generally caring about the background that much).. I'll have to try Mug's thing tonight, though..

Post an unprocessed source clip in HUFYUV instead.

To check for blended fields, do SeparateFields() and then step through the fields and see if any of them are blends of two pictures.

I wouldn't trust an app to tell me the field order. Use the manual method in the Decomb tutorial.
