D2sRoba and DVD2DVD

[Donald Nice]

Hy,

i searched the whole forum for threads about D2sRoba and DVD2DVD. I want to convert a dv to a dvd-r with Ds2Roba. What settings do i have to make? What about the max q, adjust q and Maximum q?

Thanx

Hi Donald Nice,

Settings:
- Output type : DVD
- CD size : 4480
- Number of CD's : 1
- Sample percent : 2.0
- Auto Q. (worst) : 40
- Maximum Q. : 50
- Adjust Q : 0.6
- Sizing pass : on=1 (-0.0 .. 0.0)%
- Audio after video : on=0 (% of video, 10%, min 128 kbps)
- Adjust max br : on=0 (total 2754 kbps)
- Batch prepare : on=0
- Crash recover : No

on=1 means the box is ticked. on=0 means the box is unticked.

The resizing pass is only required if you want the output size to be accurate. You can set the tolerance percentages. This is to guard against an under/oversized encode. As you can see, I set both percentages to 0 in order to force the second re-sizing pass.

Edit: These are the latest settings that I use (for v3.0.8):

Settings:
- Output type : DVD
- CD size : 4480
- Number of CD's : 1
- Sample percent : 2.0
- Auto Q / Max Q : 40 / 100
- Adjust Q : 0.6
- Sizing pass : Yes (-0.0 .. 0.0)%
- Audio after video : No
- Adjust max br : No
- Batch prepare : No
- Clean previous : Yes
- Crash recover : No

My latest visual test indicate that it is best from a picture quality perspective (particularly with high Qs) to enable the additional sizing pass.

Hope this helps,
Bob

Thanks for the fast answers. And should i use multipass VBR?

I don't understand your question. D2SRoBa is a one-pass variable bit-rate technique. The only decision to be made regarding the number of passes is whether to enable the additional sizing pass. If so, tick the conditional sizing box & enter 0 in both percentage boxes.
There is a useful guide for D2SRoBa & DVD2DVD at http://www.geocities.com/syzygydvd/help/index.htm
This guide was written by syzygytec; all credit goes to him (not me).

If you want to use conventional multi-pass VBR, then you don't need D2SRoBa; just use DVD2DVD ;try Mr Bass guide - http://www.mrbass.org/dvd2dvd/ - this is where I started.

As for which is better; have a look at: http://forum.doom9.org/showthread.php?s=&threadid=65325

We seem to conclude that OPV may be better providing that the Q is less than 40. If not multi-pass VBR is better.

However, OPV with the resizing pass enabled seems to work as well as multi-pass VBR (with Q's greater than 40), so you might as well do that.

The above represents my opinions only; other people will have other ideas. I have formed my opinions by discussion & more importantly experimentation. I urge you to do the same.

Best Regards & Good luck,
Bob
