View Full Version : Workflow of DVD2SVCD?

Hi, folks.

During the conversion of a DVD to one or more SVCDs a number of helper programs are invoked, each one taking care of one or more separate steps in the process - but exactly what is the overall workflow?

I have read around very much in several places and fora, but I never came across any kind of overview explaining the whole process or what the individual helper programs do.

What I want to know:

1) Which DVD2SVCD helper programs take which files as input and produce which files as output?

2) Exactly which piece of work does each single helper program perform in the process?

3) In which order are the individual helper programs executed? (this may depend on various user-defined settings, I know, but I want to know in general terms.)

I know this may be a very big question, but I believe many users - like me - might be interested in knowing more about the matter.

If you think I missed a page or two explaining the whole thing, then I would very much appreciate some links. Otherwise any kind of explanation will be welcome here.

Hi firkumdik and welcome to the forum..

Not sure if it its a link describing the workflow as you ask, but I can try to give you a simple answer.

Just follow D2S Tab order:

DVDRIP--> DVD2AVI -->Audio --> Frameserver (settings) --> Bitrate (settings) --> Encoder --> Matrix (settings) --> Pulldown --> Multiplex --> CDImage --> Finalize

Yes, I deliberately don't mention subtitles, because they need some processes in different points of the workflow.

Selecting AVI input, the two first steps are not needed.

And, IMHO, the best way to see and learn how D2S works is the log file (dvd2svcd_log.txt). It is very clear.

At some point after using DVD2SVCD. I wanted to know the workflow as well. I scanned all the logs and messages and tried to determine what programs were being called to do various tasks. It is rather difficult, but doable, to write it all down for a couple of reasons. First, the invocation of the modules is dependent on the source and destination. So, DVD to SVCD, calls different modules than DVD to DVD. That creates a number of different workflows to document. Then within each workflow, there are conditional branches depending on the values set in the DVD2SVCD tabs and some based internally. For example, the extraction of the audio will be followed by a routine that corrects audio tracks if a synch delay which is determined by the extraction step.

So, you can see as I did, it is no trivial task to record the workflow and logic paths. And that's the power in DVD2SVCD and why it is such a great tool. :p

Thans, everybody for your answers (sorry for the delay).

I will try to study the log file and see what I can make of it. Maybe I'll return with some more specific questions later on.

There are some rather old guides on doing the whole DVD to SVCD conversion manually. This is not identical to all the possiblities DVD2SVCD offers, but maybe you get some insight about what the single steps in the DVD2SVCD workflow are. You can follow this link (http://www.doom9.org/mpg/cce.htm) for example. There are other guides based on TMPGEnc as well, just check the guides page.
