View Full Version : For anyone with audio to video sync probs when converting from svcd to dvdr

Hi all,

Like alot of people out there, I have had major problems when coverting svcd to dvdr, as the audio always seems to be out of sync, and using the 'Create Sync Track' option in Dvd Maestro never worked for me. After a lot of messing about, I seem to have found the perfect way to sync up the two, and have created some dvds which sync perfectly. This is not the quickest method of doing this, but it works, so here are the details:

Tools Needed:

BeSweet
Dvd Maestro
Sound Forge
Tmpeg
Winamp

Method:

For the most part, I follow the svcd-dvdr guide, but, I ignore some of the stages listed. Instead do the following:

1. Use Simple Demultiplex in Tmpeg on each avseq file, so you have an .mp2 file and an .m2v file. If required, delete the .m2v to save space.

2. Load each .mp2 file into Winamp, and decrypt to .wav - Winamp also gives you the option to up the bitrate to 48k.

3. Load each .wav file into Sound Forge. Once loaded, drag & drop the second .wav file to the end of the first file. This will take a minute or two as it mixes the files. Repeat until all .wav files have been mixed, then save the final mixed .wav to disk.

4. Use the Merge & Cut option in Tmpeg to join all the original avseq files together, as per the guide.

5. Once merged, use Simple Demultiplex as per the guide - you can delete the .mp2 file howver, as we have a .wav of the audio.

6. Run the m2v file through dvd patcher as per the guide, then import into Dvd Maestro.

7. Import the .wav file you have created - this should be perfectly in sync, or only a few frames out. If not, create a synced audio track using the Dvd Maestro option. This will be saved as an .aif file.

8. Import the .aif file into Sound Forge, and save as a .wav.

9. Use BeSweet to convert the .wav to .mp2, then import in Maestro. This .mp2 should now be the exact same length.

10. Compile the project, and run Dvd Patcher on the .vob files.

11. Test in Win Dvd - the audio and video should be perfectly in sync.

Hope this is of some help to you guys having problems using the guide.

Fair enough - my point is proven then, that it isn't the quickest method. I'm not an expert with any of these tools, so I used the ones that I knew could do the job.

how would you go about doing it in BeSweet?

in the 'help' directory of BeSweet, there are two example lists, use that as a guide to your mp2 names, and you can set besweet to convert the sample rate, and to output it as one file as a single .ac3 (which is better on a DVD for compatibility reasons)

if you dont feel like reading the txt files on how to work out the command line, use the GUI, and im pretty sure you import the lst rather than the individual audio files in the GUI (i dont use the GUI)
