Problems with sound in TMPGEnc and multiplexing

[trikster2001]

Ok, so I've got this Divx movie that I really want to encode into a VCD. I tried using TMPGEnc to encode the Divx into a MPG file. Here's what I did:

1. Loaded the divx in TMPGEnc.
2. Went to Load, then chose VideoCD NTSC.
3. Went to configure, chose lowest quality (because it would take the least time) and clicked Ok.
4. Started encoding.

When the encoding finished, I noticed that the output MPG file had no sound. Piss-off number one.

Well I decided that the best way to fix this problem was to load the divx in TMPGEnc and just extract the audio. Well...when the extraction finished, loaded the file and listened...no sound. Piss-off number 2.

"Let me try again," I decided, "but this time extracting the Audio by clicking the 'System (Audio)' button." Half and hour later - still no sound. Piss-off number 3.

I tried Virtualdub, seeing as I heard it also extracts audio from video files. Well, luckily, I ended up with a .wav file with sound! Now to multiplex...

File > MPEG Tools > Basic Multiplexing in TMPGEnc. I was able to select the MPG I had made originally with no sound for video, but when I went to select the .wav file I had just made for audio, I found that TMPGEnc doesn't support .wavs. Piss-off number 4.

I did notice that when selecting the audio in multiplexing, I was allowed to choose the MP3 format. So, I loaded up Nero, and encoded the .wav file into MP3 format. Now to load into TMPGEnc...

This time an error. When I tried to multiplex the MP3 file I created along with the old MPG video file with no sound, it gave me an error "Invalid MPEG Audio Stream." Piss-off number 5.

Ok so there you have it. You can probably understand how frustrated I am...especially after nearly 5 hours of trying to get this to work. Someone please help me out...I would greatly appreciate it!

Don't know what the deal is with it not extracting the audio from the Divx properly, but up to the part after extracting the .wav, you did the right thing. TMPGEnc DOES support .wav, but not for multiplexing. Multiplexing is intended to interleave MPEG video with MPEG Audio Layer 1 or Audio Layer 2. Thus, it cannot multiplex .wav, or MP3 (which is MPEG audio layer 3), and even if it could you would never get it to play back.

What you need to do is this:
1. Select your Divx file as the video source in the main screen
2. Select the .wav you extracted as the audio source
3. Make sure it's set to generate a system stream
4. Verify your settings for the MPEG
5. Encode

It should produce an MPEG with sound.

If you want to use the video part you already encoded, then you need to run your .wav through an mp2 encoder, such as tooLame, found in the tools section, and THEN multiplex it to the video stream.

I found out the problem. Nero is stupid when it encodes wav to mp3...using some new technology called mp3pro which isnt compatible with TMPGEnc...thanks anyways everyone.

Well actually u dont need to re-encode the mpeg again, all u need to do is to demultiplex the original mpeg u made (with no sound, so u seperate the mpeg from the *so called audio track*) and then u encode the WAV file that u made from virtualdub (u can encode the AUDIO only in TMPGenc, just load the WAV dile and select audio only) this will produce your mp2 file, now just multiplex the mp2 file with the demultiplexed mpeg file from earlier, and Voilah!

(multiplexen and demultiplexen are both done in TMPGEnc under MPEG tools)

MP3 IS NOT A PROPER AUDIO FORMAT FOR MPEG VIDEO - YOU WILL HAVE PROBLEMS PLAYING YOUR MPEG IF YOU USE AN MP3 AS THE AUDIO SOURCE!

[trikster2001]

er...it works for me.

[kinneera]

I'm just saying...it's not allowed in the MPEG1, MPEG2 video encoding specification. Try sharing it with your friends and they may be sorely disappointed, as they probably won't have the same experience as you.

When I said "It works for me", I meant it worked for me on the computer...but on the DVD...it doesnt. Any other suggestions on how I can go about fixing this problem?
