Divx/Xvid conversion to DVD-Best Way

[Victor P. Magliano]

According to instructions on this website I have been performing the following steps to convert Divx v3 MPEG4. Divx v5, & Xvid MPEG4 video all coupled with MPEG Layer-3 audio to DVD for viewing on my home surround system:

Using Virtualdub, I extract the audio to a Wav file. Using TMPGEnc, I select CBR MPEG-1 Layer II audio (MP2) format, then select the source file; for video-movie.avi; for audio-movie.wav that I had created from Virtualdub. I then complete the process and encode the movie to the MPEG format. I then use Ulead Movie Factory to create the DVD. I have had success following this procedure only once. The video and audio was in sync, but the movie played with Dolby-Pro-Logic sound.

All other attempts using this conversion process has resulted in audio sync problems where the sound lagged behind the video. The time delay was constant throughout each movie.

Following instructions on how to correct audio sychronization problems, I ran into further problems with Virutaldub or Sonic Forge not allowing me to open an MPEG file so I could demultiplex the video and audio and fix the problem.

WHAT IS THE BEST PROCEDURE AND SOFTWARE TO USE FOR THIS CONVERSION PROCESS? HOW CAN I CONVERT THE MOVIE AND LISTEN TO IT ON DVD WITH DOLBY DIGITAL 5.1 SOUND.

Your help on this matter will be greatly appreciated. Thank you.

You wont get Dolby 5.1 unless the AVI has an AC3 audio stream. From what you say your AVIs have MP3 so the best you will get is Dolby Surround decoding. If the AVI has an AC3 stream then there are guides on this site (somewhere - its getting so big now!).

Thank you for your input. Could you please help me with my primary problem regarding the audio syncronization issues that I encounter evry time I try to encode a movie. Also, I am having a problem finding the proper software to compress my audio after I save it as an uncompressed wave file. I have tried BeSweet and AC3Machine, but the programs will not initialize and I keep getting error messages. I cannot post a question in the doom9.net forum just yet, because they invoke a 5 day waiting period after registration, so I still have 4 days to go. What software do you use? Your insight in this area would be greatly appreciated.

Ok, for Audio / Video synch problems in TMPGEnc, check the 'Source Range' check box in the wizard. In the pop up screen there is a field for 'Audio Gap Correct'. You'll need to play around and try out some short clips to see if you can get it to work. This only applies to audio that you are converting at the same time as the video (which is what you are doing by the sound of it).

As for software, if you're making DVD then TMPGenc & VDub should be fine for the audio. Use VDub with PCM Uncompressed audio + resample to 48000hz to save the Wav and then just import into TMPGEnc as you have been doing.

Hope this helps, let me know how you get on,

Here's an easy way that works with Xvid's with VBR encoded sound. Open the file with VirtualDub.

It will tell you with a pop-up that the sound is VBR and will cause a skew(out of sync) in the playback.

Now under the Audio tab select "Full processing mode",but add no other options.

Under the Video tab select "Direct Stream Copy".

Now Under file select "Save as avi" and put it in a new location (note: the file will be twice as large now, but in sync when you encode it)

Works every time for me!!

Thank you very much for help. I will try your suggestions in a few days when I have more time to devote to this and let you know my results.
