Avisynth: Latest Script Discussion - Page 9

Hey Kwag (and others!):

In both of your latest optimal scripts, you include the following line:

Code:

# Convolution3d or STDMedian or DCTMedianFilter for extreme worse cases.

I think I have just an example of one of those extreme cases! The movie is Tigerland by Joel Schumacher, and the entire film is shot in a very grainy handheld cam style picture. Using your optimal script for DVD and other clean sources, I get a CQ of 46.684 (using ToK). If I add SpaceDust(), the CQ goes up to 51.590 and if I add Convolution3D(preset="movieLQ") on top of that CQ becomes 56.561. So here are my questions:

- does a higher CQ necessarily mean better quality encode? To my eye the more filters I add, the softer the resulting image looks. All encodes have a lot of blockiness in the background parts of some scenes, or in dark scenes in particular. But in the encode without the extra filters the noise is more "grainy" and "sharp", and as has been previously mentioned this noise looks more realistic. With SpaceDust and Convolution3D this noise is smoothed out a little at the cost of a bit of sharpness.

- what parameters would you use for Convolution3d, STDMedian, and DCTMedianFilter? Do you recommend using all three filters at one time? If not what combo should I use?

Thanks!

Hi J-Wo,

How about trying PixieDust() and TemporalSmoother(1,2), together with the merge filters only. That should do a very good job, without blurring the picture too much.
Something like:

Code:

PixieDust()
unfilter(50,50)
TemporalSmoother(1,2)
MergeChroma(blur(1.58))
MergeLuma(blur(0.2))

Hey guys,after you put the script through tok and get your CQ,when you load the avs into tmpge do you still need to load the kvcd template also or just leave as is.

Thanx

This may be a dumb question. But how can you use these filters with moviestacker. Do you have to enter them manually ?

Not a dumb question at all

.
Yes, you have to enter them manually, until muaddib adds the filters to the next release of MovieStacker

There are no templates anywhere on ToK.You set your parameters ( MIN, MAX, etc. ) and ToK makes a KVCD automatically

The notion of a "template" doesn't exist on ToK

where do you get these filters.

ovg64 · #**168** 04-10-2003, 12:17 PM

OK, so i also have my latest optimal script

here it goesGripCrop(480, 480, overscan=2, source_anamorphic=false)
GripSize(resizer="BicubicResize")

unfilter(70,70)
Blur(0.2)
SpatialSoften(0,0,2)
MergeChroma(blur(1.5

)
MergeLuma(blur(0.2))
GripBorders()
LegalClip()

Blur and sapatial are within Avisynth you make your owen opinion about it play with the number as you like. unfilter(70,70) my be too much for some of you. This worked for me

Just a small request, but could you add a list of filters to your sticky post? Maybe even link to the versions that you are using so we can download them easily. I think most of the "regulars" here know where and what most of the filters are, but thats one of the main things to figure out as a newbie, and then the whole version skew problem that happens from time to time.

Hi bytecode,

Did you check the "Software Downloads" link on the main page at www.kvcd.net

Sorry Kwag , when tok is completely done and you get your CQ and then start tmpge to do the final encode i was wondering do you just load the avs or do you need to load a template also like in Red-M's guide.

I know its a stupid question but when your just learning and are computer stupid like myself once you add any kind of extra step it sort of throws things off a little.

your guys help is always greatly appreciated

thanx

Tom

Hi Tom,

No, when ToK starts to encode, it starts to encode

. That's it! You don't have to do anything until the process is done. Then you mux/burn and go watch TV

you can compare ToK with DVD2SVCD, except, that you do the audio source yourself. just set the bitrate and ToK does all the work, that is nessessary to get your kvcd

bigggt · #**174** 04-11-2003, 08:22 PM

Hi Kwag,i am trying not to be annoying

but i'm still not sure,i know tok does everything but all i do with it is to get the CQ(no encoding only prediction) because it takes too long to do the whole encode)

When you shut down tok and open tmpge to do the whole movie do you open the video avs that tok made or do you put the avs script that you originally loaded into Tok and then load a the template.

The reason i ask is beacuse i checked and the only difference is in the GOP tab under the part where it says Number of P picture in GOP.

THe tok avs is 24
and your template when loaded from Tmpge is 5823

Will this make a difference

By following red m's guide it says after you do the file prediction you open tmpge and then load close to the same template you used when you made your script with moviestacker,i was just wondering is this necesaryafter using tok.

Like i said the only difference is in the GOP tab

Ifd this don't make any sense(because i have trouble reading it myself)
just tell me to shut-up

and try them both.

Thanx again

Should I be able to fit one movie on one CD with this latest script? For example "15 Minutes" which is about 114 minutes long... I'm currently using a resolution of 528 x 576.
What filter am I supposed to use for deinterlacing? Do I use DecombLegacy or Bob?

Hi audioslave,

Yes, you should probably be able to fit an ~2 hour movie onto 1 disc using the latest script and the x3 template, depending on your source material (personally, I've even found a CQ level of as low as ~50 to be acceptable quality on a standard TV using the latest optimal script...my tastes may differ from yours though). For deinterlacing, you can either use Force Film in DVD2AVI (if your source is = or > than 95% Film), or you can use DecombLegacy in your avisynth script. For 23.976fps material, use the following lines right after your Mpeg2Source line:

Code:

Telecide()
Decimate()

happy encoding,
-d&c

audioslave · #**177** 04-13-2003, 09:56 AM

@ dazed&confused

Thanks for the info on the deinterlacing issue! I guess I'll have to put the movie (15 Minutes) on 2 CD's since the CQ value for 1 CD got a low as 42!

I'd rather prefer quality over a 1 CD movie. But that's just me
