It does work. My PVR-250 uses MPEG2 coefficients so you should probably use ColorMatrix(mode="rec.709->rec.601"), the video will appear slightly brighter.

:?: Where does line occur in script:

Mpeg2Source("H:\24\24.d2v",idct=7)
Undot()
Telecide(order=1, guide=1, gthresh=10, post=2, vthresh=50, dthresh=7, blend=false, show=false)
Decimate(cycle=5, mode=0, threshold=0, threshold2=3, quality=2, show=false)
aSharp(1, 4)
BicubicResize(320,432,0,0.6,4,0,712,480)
STMedianFilter(3, 3, 1, 1)
MergeChroma(blur(1.5))
MergeLuma(blur(0.1))

## Linear Motion Adaptive Filtering ##
ScriptClip("nf = YDifferenceToNext()" + chr(13) + " \
UnFilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100)) ). \
TemporalSoften( fmin(round(2/nf),6), round(1/nf), round(3/nf), 1, 2) ")

AddBorders(16,24,16,24)

## Functions ##
function fmin(int a, int b) {return (a < b) ? a : b}

It doesn't really matter. Personally I would place it right after resizing as it works fastest there since there are the least amount of pixels to process per frame.

EDIT: Why do you have UnDot() before IVTC? You should do the IVTC right after loading the source.

I checked the behaviour with DebugView and the debug parameter.

:D

Which means that you can use ColorMatrix(d2v="path\clip.d2v",mode="rec.601->rec.709") and the plugin will do the conversion if it's necessary. So that's automated processing which is always nice, you'll just have to either leave the mode parameter off (for those encoders that expect MPEG1 coeffs) or use that one which means MPEG2 coeffs are expected.

I'll have to ask Wilbert if it was possible to just take the first line and use the information stated there for slightly faster processing.

Edit: :?: Do I just delete the UnDot() line?

#ColorMatrix(d2v="path\clip.d2v",mode="rec.601->rec.709")

ColorMatrix(d2v="H:\24\24.d2v",mode="rec.601->rec.709")
Gives error (loaded into Vdub):
Avisynth open failure:
ColorMatrix: d2v file is not a dgindex project file!

ColorMatrix(mode="rec.601->rec.709"
Gives no error

I was using old Linear Motion Adaptive script from MS. Didn't know, will change. This script seems to work OK for me.

I had difficulties with "jerky" motion for a long time with PVR-250, until changing from "MPEG2 12.0MBit/sec (CBR)" to "DVD Standard Play". Now everything is smooth. I am capturing to a dedicated Western Digital 160MB Ultra DMA 100 drive and it was apparently dropping some frames.

Thanks,

Just put the "undot" line after the "decimate" line.

To use this option you need to create the D2V project with DGIndex, not with DVD2AVI.
Doing that you also need to use DGDecode.dll instead of MPEG2Dec3.dll.

What settings would be useful to use with the HC encoder?

The better is to encode a min of video without colormatriw and to copmare a snapshot with the original source.

Better yet is to use the automated processing. Use the latest DGIndex/DGDecode -combination and the latest ColorMatrix.

Add one of these lines to your script:

ColorMatrix(mode="rec.601->rec.709",d2v="path\clip.d2v") # for CCE, HCEnc, QuEnc, possibly other avcodec based encoders too
ColorMatrix(mode="rec.709->rec.601",d2v="path\clip.d2v") # for TMPGEnc

The conversion will be done if it's necessary depending on what it says in the d2v project file. If the d2v file contains more than one set of coefficients, you get an error message (I've seen one of those cases myself).

Note that the above lines assume that you are encoding to MPEG2.

I guess this is the part audioslave wanted to know.
Is it a guess or a "certain and already tested" statement ?

I encoded a testclip with the latest HCEnc and it showed no coefficients in GSpot, therefore MPEG2 is assumed. I also tested it by doing a d2v file out of the HC clip. According to DGIndex/DGDecode, it contains MPEG2 coeffs.

Thank you :)

Thank you. Both Dialhot and Boulder! :)

I must to use colormatrix + MAScript or another one, or colormatrix itself replace any other script?

ColorMatrix only changes the colors of the video, it doesn't do anything else. You can use it with any other filter.

And preferably just after the load of the source.

I've got one more question for you gurus ;).
Can I use ColorMatrix with DVD-RB? If so, how do I define the path to the *.d2v?

EDIT:
After copying DGDecode.dll to my AviSynth plugins folder both VDub and MovieStacker have stopped working. Is there a conflict between DGDecode.dll and MPEG2Dec3.dll perhaps?

It's a conflict because both contain the MPEG2Source function.

If you want to use the automation with DVD-RB, you should do a small d2v project of one of the original VOBs and point there in ColorMatrix. Any length will do.

@Boulder
I don't get what you mean by your explanation :oops: .
And what about the DGDecode.dll and MPEG2Dec3.dll, how can I fix my problem?

Remove one of the two :!:
