BD (VC-1) to SD DVD NTSC

[stanley_a]

Sorry if this has been asked before.
I want to convert (movie only of course) a 1080p24 BD (film, VC-1 codec) to SD DVD (NTSC 720x480).
I ripped the BD to my hard drive.

I have no idea how to do it.
I'd like to do it with CCE, which I own, or HC.

I haven't learned how to use Avisynth yet, but I'm a quick learner 8)

Thanks in advance.

Anyone?

you need ffdshow installed and set to decode vc-1

then use avisynth and feed to hc....use spline64resize to 720x480

you need to convert audio as well...use eac3to for that

ConvertXtoDVD can do it. Also, I *think* FAVC and The Film Machine can handle Blu-Ray as well, at any rate they can do *.mkv and *.ts, so perhaps.

If you don't already have ffdshow and Haali splitter installed, I'm pretty sure you'll need them. If you have trouble decoding VC-1 Blu-Rays, or if the end product is glitchy, try the WMP11 VC-1 codec and disable VC-1 decoding in ffdshow.

Good luck.

try the WMP11 VC-1 codec and disable VC-1 decoding in ffdshow.

I find the WMP VC1 decoder is giving a better quality than the ffdshow one.

Some tips if you plan to encode with HCenc:

Use DSS2 from Haali splitter because it's frame accurate.
Your target is a NTSC-Film DVD so you MUST encode at 23.976 FPS and you MUST apply a 3:2 pulldown.
GOP size: 12 (standard for NTSC-Film)
B-frames: 2
Of course select the correct aspect ratio

Since your source is HD and the destination SD you MUST use ColorMatrix to convert the colorimetry.
So your AVS script could be like this:

Loadplugin("C:\Program Files\AviSynth 2.5\Plugins\avss.dll")
Loadplugin("C:\Program Files\AviSynth 2.5\Plugins\ColorMatrix.dll")
DSS2("C:\Source.mkv",fps=23.976)
ColorMatrix(mode="Rec.709->Rec.601")
Spline36Resize(720,480)

Spline36Resize is giving a good quality with a good speed. You may want to try some other resizing options such as:
Spline64Resize is sharper but slower than Spline36
LanczosResize is a very good resizer but it MAY cause some artifacts

About the audio, at least one AC3 track is REQUIRED with a max bitrate of 448 kbps.

Thanks everyone.
I'm gonna try a couple of things.

I'm trying to use Brazil's script but I'm a newbie in this.
When I load the script in HC I get:
error loading AvisynthScript, Can't open D:Heat.mkv: 80004005 (D:\Heat.avs, line 3)

I have Haali installed and ffdshow with wmv9 as decoder of VC1 (the same happens if I choose the ffdshow one).
I have also put, of course, avss.dll and ColorMatrix.dll in the AviSynth plugins directory.

What am I doing wrong? What am I missing?

Thanks in advance.
