filtering to improve quality

[k-c-ksum]

there is only so much cce can do, so i want to start experimenting with filtering, nothing heavy. Ive got as far as editing the avs to crop overscan before docce4u does its magic but thats as far as i have gone, there are just to many filters out there to know were to start. Anyone have any avs scripts i can play with?

Hi! i like ddoggs combination of undot().deen() . the dlls are available through a link on avisynth.org.

also although avisynth is used in big3 i think you may find more help in the avisynth forum. -> moved

Watch out, you may have an incipient case of "filteritis". Application of filtering should be driven by specific needs of your source video. What are your needs?

I know from a PM he is doing LOTR3.

It is a tough nut encode. Not only is it 3:20 in length, but a sample showed it required 3200 Kbps to carry a CCE OPV Q-Value of Q28. On a 4.7 DVD there isn't 3200 Kbps available for this length of source. So, the decision becomes,IMO, accept a marginal encode with some potential blocking, or decrease the 'complexity' of the source via judicious filtering (Undot/Deen) as well as a little overscan cropping via r6d2's Facar script in D2Svcd/Dvd. That, along with the Bach matrix got the bitrate requirement down to around 2450 at Q28 in CCE, IIRC. That allowed a nice encode. Very crisp and looks great to my eyes.

I know compression filtering is a controversial subject to some, but in this case it can be a practical solution to achieve the goal of putting this big fat sucker on a single sided DVD with a high quality result.

Smoothing chroma stronger than luma gains some compressibility without much detail loss... ;)

thanx guys,
gonna run the movie through dvdshrink with no compression and convert a large chunk of the endcredits to stills and see what diffrence that makes.

If you're gonna do that why not just cut the credits using the avs script.

Use trim (0, last frame you want)

i'm against cutting the credits off but will settle with a conversion to stills.

How may one get hold of this "bach matrix", searching the forums didn't seem to help... :(

All the best

Hello Neuron2, :)

i appeciate a lot your adress of filters (and more).
Very complete

@Soulhunter:

tnx a lot

And what exactly would be the difference? Both options will result is worthless credits.

if this is to preserve the dvd layout you could cut the credits and use a short slideshow to keep the dvd structure intact ( as replacement for the missing chapter(s))
