[HELP] Output is 4274Mb instead of 4464Mb

[The X]

Hi, i've a problem with a film... With all version of DVD-RB that i tried the output of the dvd-5 (video_ts folder) is 4274Mb instead of the value that i set (with Rb-opt) of 4464Mb.

It's a bug of Dvd-Rb ?

TNK

P.S. The problem occurs only with the DTS audio, if i set the AC3-5.1 all work god.

totally depends on what encoding method you use, some are less precise than others

I use CCE 2.70.02 but the problem/bug is that i set, with RB-Opt, the output size and DVD-RB ignores it; the problem occurs only with the dts audio track.

doesnt ignore,

what are your settings. If you are using opv, then with a slightly different Q (due to less available space via the DTS track) you have huge swings in size

What does OPV stand for?

The problem could be that even when you set RB to process in VBR, it can set some small segments to be processed OPV. Bur when you use RBOpt, it applies the encode method of the last segment of a VOBID to the whole VOBID. If it was OPV, it uses OPV for the whole VOBID. And OPV is not so exact in meeting size targets, specially at high bitrates (or low Qs)

What does OPV stand for?IIRC it stands for One Pass Variable bitrate - One Pass VBR :)

Ah.... i understand... but the solution is ? ^_^

The solution is to back down the TargetSectors size. Are you using OPV? I'm not sure whether that's clear to me.

In RB-OPT i see that it's selected "VBR" and the option "Enable OPV for small VOB-IDs" isn't select....

Have you tried doing the movie without RB-Opt? If you are getting unusual sizing with RB-Opt, the error isn't likely one related to DVD-RB.

Yes, of course! I tried 2 times... Without RB-OPT instead of 4424Mb the output is 4274Mb.

Finally I do it !

Setting 4658Mb with RB-Opt, DVD-RB creates an output of 4450Mb....
