Avisynth: Motion Adaptive Green?

CheronAph · #1 06-14-2003, 12:15 AM

Just tried the script, I get a green screen in tmpgenc, I have avisynth 2.52 installed!

## DLL Section ##

asharp(2, 4)

#
#

## Dynamic Linear Adaptive Filtering and Scene Change Detection ##
#
# ( Portions from AviSynth's manual ) - This will apply temporalsoften to
# very static scenes, and apply variable blur on moving scenes.
# We also assign a variable - and this is why a line break is inserted:

ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf > 2.5 ? asharp( -(fmin((nf/30), 1)), 0 ) : \
TemporalSoften(2,7,7,3,2) ")

#
# Scene change detection ( kwag ) - If a scene change is detected, we
# blur heavily. This affects the scene before and the one after the
# scene change, thus providing a softer transition for the encoder instead
# of a sharp "spike".
# If it's not a scene change, then we just blur dynamically, depending on
# the action.

ScriptClip("nf > scd_trigger ? asharp( -2,0) : asharp(0,0) ")

#
#
#

#LetterBox( Your_Values_Here ) # Depends on situation. Use MovieStacker!
AddBorders(16, 17, 16, 17) # Depends on situation. Use MovieStacker!
Limiter()

#
## Functions ###

function fmin(float f1, float f2) {
return (f1<f2) ? f1 : f2
}

Hi CheronAph,

The problem is probably in your source. Open your .avs with Vdub, and see if it looks the same. There, you'll probably get an error. Check your DivX CODEC version too

It has to be in the script, I tried an .avi that I have already encoded with a normal script which worked fine, with the new script it´s the green screen again!

This line could be the problem. You should always crop in even numbers!

EDIT: There's something wrong with that line. It should be BicubicResize(672, 542, 19, 15, 634, 512) but that's not correct either (for the reasons above)

CheronAph · #5 06-14-2003, 05:19 AM

I used moviestacker to get that line!

CheronAph · #6 06-14-2003, 05:26 AM

I used fitcd to get the right rezise and it works, now the problem is that tok won´t do the predict when it starts to make the samples, only black screen appears?

@CheronAph,

Double check BicubicResize paramaters:

Example of 704x480 with tv-overscan of 2:

BicubicResize(672,446,0,0.6,0,1,720,47

I´m using BicubicResize(672,544,0,0.6,4,0,632,512) to 704x576 and I can encode it but prediction with tok doesn´t work???

Jellygoose · #9 06-14-2003, 09:19 AM

Did you point TOK to the Sample-2.5.dll

CheronAph · #10 06-14-2003, 01:44 PM

No I didn´t, I´ll try that!

Uhmmm, where can I find it?

CheronAph · #12 06-14-2003, 02:55 PM

I´ve got it now, it´s working, thanks all for your help!

What kind of movie is that

Seems it's a very high activity movie or something, because the CQ that ToK gave you, is close to the wanted sample size. So that's it

CheronAph · #15 06-15-2003, 01:48 AM

It´s a cartoon, Fox and a hound, old Disney movie!

kwag · #16 06-15-2003, 01:54 AM

Well I think you're going to have to go lower in resolution for that movie. Maybe 352x576

CheronAph · #17 06-15-2003, 02:11 AM

Does this motion adaptive thing have the same compression or does it automatically make larger files?

The motion adaptive filter script will make WAY smaller files than using static filters. Like the ones used on 2.0x series.
Bed time, see you all tomorrow

Then something is wrong, same movie optimal script!

Don't now what to say, because my results are just the opposite

But then, I'm doing NTSC, so I can't compare to any PAL stuff
