Hello,

I am using MeGui to Deinterlace some 480i Basketball games I capture from HDchannels through S-Video and encode them to x264. I find the Internal Deinterlacers that come with MeGui to not properly deinterlace the games and the final ouput doesnt look very well after encoding. Could anybody give me some insight on what deinterlacer(s) would do the proper job of deinterlacing it as much as possible? Any help would be appreciated. If you need more info please so ill provide it ASAP.


I Have included the untouched sample and the encoded sample. Please tell if im correct when i say its not entirely deinterlaced.

Untouched Clip (http://www.mediafire.com/?ccnpsxnnsci)

Encoded Clip (http://www.mediafire.com/?22nszxilmee)

The avisynth script Megui created for the clip is :

DGDecode_mpeg2source("C:\Documents and Settings\gaby\My Documents\sample.d2v",info=3)
ColorMatrix(hints=true,interlaced=true)
Load_Stdcall_Plugin("C:\Program Files\megui\tools\yadif\yadif.dll")
Yadif(order=1)
crop( 10, 58, 0, -64)

Are you talking about the aliasing on the court markings?

@ neuron - Yes sir. Sorry if i hadnt expressed myself properly. I just figured out the term was called aliasing just a few moments ago.

I've seen MCBob + NNEDI recommednded for this sort of thing. It's slow, though.

Some dude recommended :

tdeint(mode=1, emask=tmm(mode=1), edeint=nnedi(field=-2))

you need to load the plugins nnedi.dll tdeint.dll and tmm.dll from tritical

Are the screenshots correct on how to input what i was told by another user ? it seems to do the trick but it encodes very slow.

Looks fine to me. Effective directional interpolation is processor intensive. You'll have to live with that if you want the results it gives.

Oh well, I'll give a game a go and see how long it takes to encode. Thanks for the info, i really appreciate it.

Is there any way I can get the FPS back to 30?, because when I encode with the settings above the FPS go to 60FPS.
