Color....blending?

Postby Kazemon15 » Wed Oct 21, 2009 4:28 pm

I was wondering if anyone can help me...

Okay here it goes. I'm cleaning my R2 DVDs for an AMV and everything for the most part looks nice and shiny....except for a few frames that seem to have some color blending on them. This is the only time so far I've seen them on the whole DVD. Maybe avs just hates orange? XD

Thanks in advance.

That's an issue with the IVTC. Gotta try some other ivtc settings or another ivtc chain altogether. Post your script?

Never heard of IVTC...

Code: Select all
ConvertToYV12()
Telecide(1)
Tweak(sat=1, cont=1, bright=0)
Awarpsharp(12)
Deen("a2d",3,7,9)
crop(6,40,-6,-40)
LanczosResize(848,480)


This is a script my friend gave me for cleaning fake AVIs.

Thanks for replying. =3

ivtc is inverse telecine... you're doing half of it, the telecide is the field matching, and there should be supposed to be a decimate step, in your case with decimate. However, telecide and decimate are rather old filters, you should use tfm and tdecimate. You can get them with the TIVTC package.
Then change your telecide(1) with tfm() and it should turn out better.
I'm assuming you aren't decimating because you need to edit at 29.97 fps for whatever reason, but otherwise, I'd suggest you to decimate back to 23.976 by just putting a tdecimate() in the line below the tfm().

I edit in 29.97 because it's easier for me. Frame rates bug the heck outta me. XD
Thanks alot, I'll try it. =3

Is it possible to use tdecimate with 29.97 fps?

And should I redo all my R2 dvds with tdecimate? I used telecide for my other R2's. (Same company and anime)

tdecimate is to get 29.97 back to 23.976. You're mixing it up with tfm(), that's what you should use instead of telecide(1). ;)
And yes, it is possible to use tfm() with 29.97.
As for redoing all your DVDs with tfm(), it's not necessary unless you find a lot of these chroma blending artifacts and you want to fix them.

I tried it. Here's the result:

Seems like it's still there with a little more lines now...

AH I see. Sorry. XD I'll try it again:

Heh, that's probably one of the frames that would get decimated out when getting the framerate back to 23.976 from 29.97. Perhaps you could decimate to 23.976 and get the fps back to 29.97 with a changefps and see how it goes.

Is that Gokudera?

Anyway, you might want to try setting chroma=false in your TDecimate call. If you're lucky, this will increase the chance that a frame with chroma not matching the luma is seen as a duplicate (because only the luma will be considered) and removed.

I really hope this isn't as bad as the footage in this thread was, but we'd have to see a lossless clip containing a known problem area in order to tell for sure.

Yup, it's Gokudera. Apologizing to Juudaime... XD

Anyway..here's the lossless using this script:

Code: Select all
ConvertToYV12()
tfm()
tdecimate()
Tweak(sat=1, cont=1, bright=0)
Awarpsharp(12)
Deen("a2d",3,7,9)
crop(6,40,-6,-40)

If you use these settings with TFM, does it help?
Code: Select all
TFM(order=-1,mode=5,PP=7,field=-1,slow=2)


Basically that's telling it to use a lot more precision than just TFM() will.

Er... when I said "lossless", what I really meant was "lossless and straight from the DVD with no processing applied to it". Sorry ^^>
