Mp2 Audio question...

[OhmGautama]

I have a quesiton regarding the "encoding your audio for distrubition" section in the AbosoluteDestiny and Ermac Technical guide, specifically the mp2 encoding section. It says in the Audio Engine tab, point to the tooLAME program. It shows on the picture MPEG-1 Audio Layer 2 and 3 encoder options. The guide says the one I need is the Layer-2 (mp2 audio) which should point to the tooLame file. In the picture however, it shows the "lame.exe" pointed to under the MPEG-1 Audio Layer 3 encoder. Is this picture correct? or is the lame.exe under the mpg audio layer 3 tab another exe file then the tooLAME program? Or should ignore the picture and choose the lame file for the MPEG-1 Audio Layer 2 encoder?

Also another question, next in the section it says "Audio encoding settings in TMPG are fairly simple and the minimum quality settings I think you should choose are:". So when Im encoding my audio to mpeg 1 format, will I be encoding my video and audio file at the same time. Using my AVI synth file as my video input (exporting with the MPEG1 AMV profile) and then using my previously exported wav file from Adobe Premiere Pro as my audio input (exporting as the MPEG-1 Audio Layer 2)? The only reason Im asking is that during the "compressing your audio to mp3" section they attach the audio file afterwards to already compressed file. Should I do that with my mpeg-2 audio compressed file or will I do as I mentioned earlier and export the video with the audio at the same time?

The tooLame.exe you are looking for is C:\Program Files\AMVapp\Audio Apps\BeSweet\tooLame.exe assuming you installed the AMVapp in the default location.

As for the MP3 encoder lame.exe, it could be in the same BeSweet folder, but more likely, it's in its own location. For example, mine is located here: C:\Program Files\lame-3.96.1\lame.exe.

<s>If you are using TMPGEnc to do the encoding and are using the MPEG-2 Project Wizard, by default it will produce a muxed MPG file if you selected your audio as CBR MPEG-1 Layer II Audio (MP2). You won't need to mux (attach) the 2 streams in a separate step unless you selected to output elementary streams (which would have TMPGEnc produce separate M2V video and MP2 audio files).</s>

BUT, if you are producing a MPEG-1 file and using the Project Wizard, TMPGEnc will always produce a muxed MPG file.

If you aren't using the Wizard, then selecting System (Video+Audio) in the Stream type box in lower right corner will produce the finished MPG file for you.

Ah ok Thanks!

Btw do I lose any quality of audio from not adding(muxing) later, like with the mp3?

[Willen]

Nope.

Great thanks again Willen!
