Having problem setting bitrate in dvd2svcd

[telemike]

Q7: I don’t want to use your average bitrate calculation, how do I override it to use my own?
A: Just type in the same average bitrate you want to use in both "Max. avg. box" and "Min. avg. box" in the Bitrate Tab. This is not recommended unless you are experienced and have a special need.


I have set the MAX AVG to 2500, MIN AVG to 500. Checked the box.

However, when I attempt to backup a dvd that is 179 minutes, it goes into CCE at about 1642 as the max bitrate.....

I have my file split size set to 790MB. I am using CCE 1-pass VBR too.

Can someone help me set D2S to do 2500 max, 500 min on this? Is there a certain way to set the bitrate tab to do this? Thanks.

Let me see if I understand you correctly.

You set the MAX AVERAGE to 2500, and the MINIMUM AVERAGE to 500. Yes?

I think you need to set those to values both to 2500, I don't use that mehtod, but that is what I am getting from Q7. So you would have MAX AVERAGE 2500, MIN AVERAGE 2500. Its going to split that 170 minute movie into five discs.

The AVG is confusing.

Basically what I want to do is:

Encode with CCE using 1-pass VBR
Max bitrate = 2500
Min bitrate = 500
Audio bitrate - 160 dual channel

Let CCE vary the bitrate between 2500 and 500 for the movie, let BBmpeg split the movie at 790MB and the number of cd's be random. I want the max quality for high motion (thus the 2500), 1-pass VBR for speed.

So.........

the best thing would be to set the bitrate like this:

Max = 2530
Min = 500
Min Avg = 1750 (checked)
Max Avg = 2230

and this should do what I want DVD2SVCD and CCE to do.

I used to use TMPGenc with CQ file prediction but CCE is much faster

I set the min avg set to 1600, but yes what have listed should do what you want.

[telemike]

Do you check the box for min avg?

[onisama]

yes, but if you watch what D2S uses as an avg bitrate (what is calculated at the right side of the window) and make sure that doesn't go below what you have set for the min avg, it doesn't matter whether it is checked or not.

Thanks. much clearer now! :D

This is exactly what the plugin I made for D2S is supposed to do: http://home.no.net/tylo/
The plugin select One-pass VBR in D2S.

1. Select a Q.factor, e.g. 25 (very high quality) - 40 (fair quality).
2. Tick on "Compute num. CD's" - number of CD's to achieve requested quality (~ Q.factor).
3. Tick on "One-pass vbr RoBa" - will fill the last CD to the limit. (Set Q.Adjust down to 0.0: it assure that the last cd image does not get too big)
4 Hit Go. D2S starts. Make final settings, and go.

PS: Hopefully you both meant Multi-pass VBR (N=1), (which is two passes), when refering to 1-pass VBR, otherwise most of your discussion above would be pointless. One-pass VBR does not use any avg. bitrate at all.

Good luck.
