What does it have to recompress the sound?

[jimcgr2]

Hi

I haven't used SVCD2DVDMPG+ yet but I plan to do it tonight. My big question is why is it a must to recompress the audio part ? (As I could see from the guide...)

I mean if I have a perfect mpeg file, the sound in it is already compressed correctly, is there a way to tell SVCD2DVD not to touch my already clean and perfect mpeg file?

Also what if I already have an ac3 sound file? Again why isn't possible to tell SVCD2DVDMPG+ to use my ac3 sound file and not to launch its own ac3 encoder???

Thanks!

Hi jimcgr2,

SVCD2DVDMPEG transcode the audio to 48KHz in order to be DVD-Compliant. This is the case that you want to put a VCD on DVD. The VCD's resolution of 352x240 is DVD-compliant, but a VCD's audio of 44.1 KHz is not. If your MPEG clip has an audio of 48KHz already, you don't need to use SVCD2DVDMPEG.

About the AC3 question, some DVD-Authoring S/W can handle AC3, and some can't, but all of them should be able to handle MP2 Audio.

About SVCD2DVD, I don't know, because I have never use it. You should ask the author. It was a good question though.

Cheers,

Thanks for your response!

But when you say that if my audio is already 48Khz I don't need SVCD2DVD, then can you point a DVD authoring soft that will let me build a PAL 480 x 576 DVD ?

The reason I needed to use SVCD2DVD is that TMPEnc DVD Author won't let me use a 480 x 576 movie to make a DVD. It tells me that this format is invalid for a DVD...

Hello Jim

You may like to try out Mediachance DVDLab, which will accept SVCD straight + audio in all acceptable formats. If it requires, it would transcode it to make it DVD compatible (ie 48KHz sampling)

@Jim, like you I'm new to svcd2dvd so this is a bit of blind leading blind

You can tell svcd2dvd not to resample audio via a radio button on the settings window, - I generate 48kHz audio using BeSweet. SVCD2DVD will want to do an mpg>m2v+mp2>mpg [i.e. demux remux] step, I'm looking for a way to avoid that - maybe it's neccesaary for chapters but I don't see why.

if you have 48K audio it will not be resampled (SVCD2DVD will automatically skip this step).

SVCD2DVD remuxes in order to restructure the program streams for DVD authoring. Most other dvd authoring packages also do this but as part of the authoring phase. SVCD2DVD does b4 the authoring phase (which as a result is shorter)
