Sorry if this has been asked before.
I want to convert (movie only of course) a 1080p24 BD (film, AVC codec) to SD DVD (NTSC 720x480).
I ripped the BD to my hard drive.
I want to do it with CCE.
Until now I've been doing it with HC.
This is what I've been doing.
First I run the AVC file through DGAVCIndex.
Then I use this AviSynth script and feed it to HC.
LoadPlugin("C:\Program Files\dgavcdec109\DGAVCDecode.dll")
Loadplugin("C:\Program Files\AviSynth 2.5\Plugins\ColorMatrix.dll")
AVCSource("D:\movie.dga")
ColorMatrix(mode="Rec.709->Rec.601")
Spline64Resize(720,480)
How should I do it if I wanted to do it with CCE?
Thanks in advance.

Are you asking what should your avs script be? It would be the same
But I would consider using clamp=0 for colormatrix, otherwise it will clip values 16-235 for Y' and 16-240 for UV
ColorMatrix(mode="Rec.709->Rec.601" , clamp=0) -
I agree. And I've always wondered why so many AviSynth filters clip by default. Not just the ColorMatrix filter, but really important ones like Tweak and Levels. For CCE I'd also convert to YUY2 in last line of the script:
ConvertToYUY2()
pdr, do you think he should resize to 704x480 in the script instead, adding black bars to fill it out to 720x480, if desired? -
I don't know manono , you have way more experience with dvd than me.
For precise aspect ratio , that is more correct thing to do (704x480 with 8px L+R letterbox) . Myself, I never do it that way and live with the slight error -

ColorMatrix(mode="Rec.709->Rec.601", clamp=0)
works in the version I'm using. That's version 2.3. Maybe there's a newer version where it's changed. -
This is what the HTML file that comes with the dll says:
clamp:
Specifies whether pre/post clipping with limiter to 16-235/16-240 should be used. Possible settings:
true - pre/post clipping
false - no pre/post clipping
true is what previous (v1.x) versions of ColorMatrix used.
default - true (int)
So, what should I use?
