View Full Version : Recommended settings for HC at ~2000kbps

Okay, this is a tough nut to crack so I wanted to ask some tips from people that have done similar cases before.

Band DVD HIM-Love Metal Archives is way over 8gb, so the reduction level with DVD-RB is 53,1% (after MenuShrinking) and overall bitrate at 1944kbps.

As you may guess, the disc contains music videos and live footage - really a worst case scenario.

Using DVD-RB Pro and HC (or some other free encoder?) - what settings could I use to optimize the result? Matrix recommendations?

I am currently testing with the CG Smooth matrix, which is preconfigured in DVD-RB - am I on the right track?

script avisynth optimisation is IMO very better for that ...

- make DAR 4/3 and not DAR 16/9
- use mode16 resize for real image
- use overscan compensation
- filtering for better compressibility

Classique scenario encoding : source 16/9
PAL DAR 16/9 720*576 with real image 720*576 = 415 000 pixel

optimized scenario encoding : source 16/9
PAL DAR 4/3 720*576 with real image 688*416 = 285 000 pixel

2000 Kbps is a very good bitrate for real 688*416 source ...

Take a look on my matrix AutoQ2. It is the same like in my programs. It produces a realy good picture quality even in low bitrates. The matrix is build in.

Ok thanks for the responses. I shall give the "AutoQ2" a shot.

Damn, these matrices really need to be documented with target bitrates and use cases that they are designed for. I can't understand why such table is not available...

how would that look in a script? script newbie here

Hey, a stupid noob question: How do I pass the matrix setting to HC while using DVD-RB Pro latest version in HC mode? I guess command line parameters sent by RB override the .INI file?
