D2SRoba - Oversizes

[kilg0r3]

Hi

currently I am trying to rip 'Luther' with two audio tracks. But D2SRoba seems to ignore one audiostram in its size calculations. So I always get oversized final files
This has been the case with the 3.6 version as well as with 3.74. Thanks in advance.

Cheers, kilg0r3

Shouldn't that read video_sz= 4112144016?

- D2S audio select : 448 + 448 kbps
- D2S video calc. : 4949 kbps, 1 CDs

The bitrate is directly retrieved from DVD2SVCD's calculations, and D2SRoBa bases everything on this. The video bitrate here should have taken the audio bitrate into account.

4949 kbps * 1000 / 8 * (177672 frames / 25 fps) = 4396493640 bytes
- looks too big

((4949 + 448*2) * 1000 / 8 * (177672/25) = 5192464200
- including audio - way to big

This is an error I have seen from time to time, and it appears that DVD2SVCD sometimes does not calculate the target bitrate correctly. Actually, DVD2SVCD does not have to do it in OPV mode, because it doesn't use it. It does it anyway, but maybe/apparently a little more sloppy than in multipass VBR or CBR mode, where it must have it right.

I could change so that DVD2SVCD starts in multipass mode, so that you can clearly see that it is the DVD2SVCD's calculated bitrate that D2SRoBa bases its work on. D2SRoBa must then change to OPV for its own encoding.

Please try without D2SRoBa, possible both in OPV and VBR multipass mode, to see which bitrate it chooses.

Sorry couldn't make your tests with the same DVD because my wife gave my DVD away :angry:.
I tries to reproduce the problem with another DVD but , think what, it worked out allright. :confused:
