View Full Version : Why use virtual dub or R4R?

I own a legal verson of 'Placebo - Soulmates Never Die'. I'm copying it to my HDD in the XVid/mp3 codecs and then cutting it into individual music videos. I have made a perfect copy with GordianKnot and BeLight and it seems in-sinc.ect then i cut it with virtual dub at the keyframes; no problems :)

Here is my question: I have decrypted the entire DVD disc to my HDD as an iso image and mounted it with DTools. I then open DGIndex.exe and configure to demux the audio steam i want. Now at this point I can 'Save project' or i can 'Save project and demux video'.
Is there any point in demuxing the video?
IF i just save the project i can load the d2v file strait into GordianKnot and GK will simply encode the video through DTools off my iso image.
Alternatively i can save and demux the video to m2v files and unmount my iso image in DTools and GK will encode the video from the m2v files. (i think m2v is correct but i might have remembered the extension wrong). Both methods seem to yield the same results.

Also there is a guide on doom9 which shows how to start frame servers and encode through virtual dub.. what is the point in this? - surely virtual dub just opens the xvid codec and does exactly the same thing as GK?

I have tried encoding my DVD from both m2v files and with a d2v project linked strait to the iso image and both rips seem identical in quality. Please tell me if i've done something horribly wrong.

Is there any point in demuxing the video? For your application, no. Demuxing produces a video elementary stream. One possible application for that is to replace the audio track. You'd demux the video and then remux it with the different audio track. It's safe to say that if you don't know why you'd need a video ES, then you don't need one.

I don't understand the question... IIRC GK is using VirtualDub to encode video, but not everyone wants to use GK.
