Converting Audio From 44.1 Khz To 48 Khz In A PAL VCD!

[sohaibrazzaq]

Hi,
As the title says what this post is really for. I have some old classic PAL VCD movies which i want to put on a single DVD-R to avoid disc swapping in the Player.
Firstly, i tried to create DVD from these VCDs directly using Ulead DVD MovieFactory 4.0.4 Standard Edition so that it automatically encode audio to 48 Khz while leaving video un-touched but the resulted movie that came out had audio out of sync played on computer as well as on my DVD Player.(The source file has no audio/video sync issues) I also tried DVD Author 1.5 but it gave me error during compilation.
Now i planned to manually demux the movie, convert the audio to 48 KHz and then multiplex it back while leaving video as it is to maintain the already humble video quality of this VCD. Which tools i use to do that work?

I also tried DVD lab Pro 1.53, it demuxed the movie to elementary streams and converted the audio to 48 KHz, closed dvd lab pro and muxed the video and encoded 48 KHz audio using muxman and the audio was now again out of sync, but this time it was less compairing to one that came with MovieFactory.
Plz tell me the best tools to do this job or and alternative method.
Thanks,
Sohaib

Use vcdgear to extract the mpeg as mpeg , not dat .
Then use visualsubsync to pull the audio from video file as wav .

Use besweet to convert this wav to 48khz .

Unfortunatley , vcd's are a right pain to reconvert backward's ... and the method I use is long as it involve's vcdgear - movie maker - dv1 - convert to dv2 - rencode to mpeg2 (no resize) .

I prefer my method even though some dont understand why I go from mpeg to dv avi to mpeg .

Movie maker will understand the audio , but output as dv1 , which need's conversion to dv2 before vitualdub will understand the audio .

Having tried many program's and tool's to convert , I have never been satisfied with the outcome of the video quality , as it suffer's in all case's .

While my method seem's long , the video suffer's less problem's , and audio stay's in sync at all time's .

The guide for this is almost completed , and should be online in a day or so ... when I find all my snap's ... too many folder's .

Have you considered using SVCD2DVD? It's at:

It's trialware. I used it to successfully convert a PAL VCD to DVD.

If you have sync problems, demux everything and author it with IFOEdit's barebones DVD authoring option. You can give a + or - value to the audio offset to be used in the mux and that might fix your problem. You'll have to do it several times until you guess the right value. In some cases, it may be too messed up to get back in sync this way, but I have used it before successfully to fix a sync problem in a VCD to DVD conversion.

If you have sync problems, demux everything and author it with IfoEdit]

Ifoedit dose not touch mpeg1 video stream's , only mpeg2 encoded is acceptable .

Demux with Project X, then trancode the audio with Besweet using belight as front end, after that use ifo edit to create vob and ifo files.

correction see my prev. posting
u can use tmpegenc: (free version might do the trick) go to mpegtools en mux the audio en video together and after that 1 u can load the whole thing back in movie factory/
I think u have to use the CIS option or better stil 2: use dvd styler or simple dvd both freeware


had overlooked the fact that ifo edit does not accept mpeg1

Bjs - Then would you like to explain how exactly I was able to use IFOedit to author a DVD using an MPEG-1 video stream? Because it sure DID work! Have you even tried it? I used IFOedit to examine my stream after making the DVD and it says it's MPEG-1.

Or just extract the "raw" mpeg1 files (including audio) and burn them to disk .. as raw mpg1 files (NERO -DATA DISK) a lot of DVD players will play these, especially the cheaper ones from China. Of course add both disks together to make 1 mpeg1 file. You should be able to fit 4 or 5 of these files onto one dvd or if you use DVD-r9 maybe 10 or more...nice. Test using RW disks.
