Beginners Guide To Ripping With Gordian Knot

RedVeil

If I don't call deblock_qed() I get the same result as if I were calling it.

Thanks for the hint to the other Plugins, I got them already. :wink:

elguaxo

Then something is wrong on your side. Blocky sample and the script I used:

Code:

DGDecode_mpeg2source("H:\videos\samples\SampleWarrior.d2v")

deblock_qed( quant1=30,quant2=60)

crop( 0, 0, -2, -4)
Spline36Resize(720,400)

RedVeil

You are right! It really does some deblocking, only the difference between source and result was so small that I barely even noticed - so I changed the parameters, like you mentioned.
So I used both (deblock and dfttest) functions now and must say that the output is very nice. Thanks for your help elguaxo!

Hmm, I think this is a difficult one:

The frames in my current rip are 25 fps PAL but(!) interlaced. So there are no full frames only half frames. What do I use in such a case?

EDIT: Sorry it is interlaced NOT de-interlaced. :oops:

elguaxo

post a sample :wink:

Interpolation

1) Quick - Yadif: http://forum.doom9.org/showthread.php?t=124284

Code:

Yadif(order=1)

2) Painful but will get tiny more details here and there - TDeint / TMM / NNEDI combo:
http://forum.doom9.org/showthread.php?t=82264
http://forum.doom9.org/showthread.php?t=129953

Code:

Interp = nnedi(field=1)
TDeint(order=1,field=1,type=1,edeint=Interp,emask=TMM(order=1,field=1))

3) Beyond painful

- MCBob or TempGaussMC. I used MCBob only once and I know I won't use it ever again. :mrgreen:

RedVeil

When I use nnedi I get the following AviSynth error message:

Quote:

error:"nnedi: height must be mod 2!"

Here's my current script. The height should be dividable by 2. :roll:

try deinterlacing before cropping.

RedVeil

OK that helped me to get rid of the error, so I am currently doing this:

sc01 = trim(0, 756)
 
interp = sc01.nnedi(field=1)
 
sc01.tdeint(order=1, field=1, type=1, edeint=interp, emask=sc01.TMM(order=1, field=1))

But the result still looks interlaced like before.

EDIT: I forgot the "sc01 =" in the last line. :oops:

sc01 = sc01.tdeint(order=1, field=1, type=1, edeint=interp, emask=sc01.TMM(order=1, field=1))

This does work well! THANK YOU!!!!!!!!! :googley:

elguaxo

it's probably the trimming. try without trimming and if it works, you'll know where the problem is. :mrgreen:

edit: fixed! great

RedVeil

One last question regarding the result of the interpolation.
In scenes with fast movement the interpolation results in objects which are not really there.
Look at the example below. The bottom image is the original interlaced frame. The top image is the same frame interpolated.

Is there any way to get rid of those "unreal objects"?

elguaxo

Fieldblends. I'd try bobbing (50fps) and then restoring it to 25fps using srestore.

bobbing script similar to the deinterlacing script you are using now:

Code:

Interp = nnedi(field=3)
TDeint(mode=1,order=1,type=1,edeint=Interp,emask=TMM(mode=1,order=1))

and then Srestore:
http://forum.doom9.org/showthread.php?t=95924

Code:

srestore(frate=25,cache=5)

The latest version of Srestore has a big memory leak:

Last week I had to process the video in smaller so I wouldn't run out of RAM: url=http://bad-good.org/phpBB2/viewtopic.php?p=121643#p121643

RedVeil

After adapting the script there are still Fieldblends like before. What am I doing wrong?

sc05 = trim(3351, 3666)
interp = sc05.nnedi(field=3)
sc05 = sc05.tdeint(mode=1, order=1, type=1, edeint=interp, emask=sc05.TMM(mode=1, order=1))
sc05 = sc05.srestore(frate=25, cache=5)

RedVeil

Sorry for being such a newbie but I can't seem to get this working. :oops:

Which means: I apply the Srestore function and the result looks the same.

Sure thing elguaxo. Here is the whole part: http://rapidshare.com/files/191172910/r ... d.m2v.html (it's pretty short)

Elguaxo, have you downloaded the sample?

I have it, I'll take a look tomorrow!
