View Full Version : D2Sroba vs Big 3Method with Roba

Hi,

I only recently started to do DVD backups, read a lot of the faqs and guides on this forum and tried out the different presented methods.

I'm having following question, on which I could not find the answer(I did search in the forum).

How do DVD2SVCD with the Roba plugin and the Big 3 method relate for the encoding part?

Am I correct in assuming that D2SRoba is similar to doing the Big 3 method with using 1 instead of 3 VBR passes as documented in the guide, or are there more differences?

If so is there a way (or need?) to get D2SRoba do more passes?

Thx a lot for clarifying this to me or pointing me in the right direction.

Hi walkistalki,

Let me attempt to clarify:

1. D2SRoBa uses DVD2SVCD (which uses CCE, TMPG or Procoder) in order to re-encode a film using OPV (One Pass Variable bitrate) encoding. If the output size is not within a specified percentage of the target, then an additional VBR (Variable Bit Rate) sizing pass can be used - it's your choice selected prior to encoding. So you see, D2SRoBa is a maximum of 2 passes.

2. It is possible to use DVD2SVCD (without D2SRoBa) to do multipass VBR encoding usually using 2 to 4 passes. This would in fact become 3 to 5 passes since a video information file pass is required before encoding can commence.

It is my and other forum members' opinion that option 1 is capable of generating similar picture quality to option 2. Although I would stress that you enable the variable sizing pass for high Q encodes (>40). Since option 1 requires less passes, people prefer it.

Both the above options can only do main movie only (no menus or special features etc). In order to encode the whole disc, 'The big Three' are used (it is called this because 3 software tools are required). So you see, 'The Big Three' is an entirely different process for a different requirement.

I hope this helps - any more questions please ask. BTW - I have never used the big three, since I am only interested in the main feature.

Regards,
Bob
