View Full Version : Deinterlacing Issue (Helpful newbie)

Hello! I've been doing some tests with x264 (AutoMKV), and I ran into a deinterlacing problem.
I'm trying to encode Friends episodes from PAL dvds, and I get this result quite often:

Now, I noticed AutoMKV is using "Tdeint(movie,order=1)".

Out of curiosity, I tried to encode with AutoGK to see which deinterlacer would be used, and I got this: KernelDeInt(movie,order=1,sharp=true)... The result wasn't the same has Tdeint, I think it was visually better, but still had frames bad deinterlaced... Now, I'm not expert of this subject, but I was wondering if there isn't another(better) method to do it?

I've posted a sample of the episode in question, you can download it here:Sample (http://rapidshare.com/files/45346876/sample.rar.html)

Also, for another TV Show I'm trying to encode... DGIndex says the frames are interlaced, and that is true for some of them, but the majority is progressive (I noticed that the opening credits, the ending credits and that one scene of the whole episode is interlaced, but there's probably a few more scenes)... What should I do in this case? If I apply the deinterlacer filter, I will lose quality in the scenes that didn't really need it, right? But if I don't, I'll see the lines in every interlaced frame :helpful:

Oh, and I forgot to say... I'm not doing any resizing to the picture, it's staiyng at 720x576.

I hope you can help me with this. Thanks in advance.

allowing AutoMKV to use Hybrid Patter, it will use this deinterlace script

edeintted = movie.SeparateFields().SelectEven().EEDI2(field=-1)
movie = TDeint(movie,full=false,edeint=edeintted)

and the result is this http://www.64k.it/andres/data/a/samukas.avi

That is so much better, indeed! Thank you, buzzqw :)

About the other case, is there any special option/method I can use? Or do I really have to apply the deinterlacing filter, even though there are very few scenes with interlacing?

about other tv show, i will use the standard deinterlacer (leakkerneldeint) . On no interlaced frames it will do nothing (near...) on interlaced it will deinterlaced it

surely the deinterlace will lower the quality... but do a simple test, one with deinterlace (in automkv set deinterlace as Interlaced, and set order as reported by dgindex) , and one with deinteralace set to NONE

happy encoding :)

P.S. in previus encoding (friends) i have used the Hqdn3d(4,3,6,4.5) filter...
