MPEG audio encoding

[Lamp]

I have a *.mpg music video and I am working with TMPGenc Plus 2.5.
Ive been advised to use the ES(video only) option, and to use another app in order to obtain the audio...I just dont know witch one.

Cud u guys list sum of those apps here?

If your final product is a DVD, you can use a program like ffmpegGUI to convert the audio to AC3, it that's what you want. It's the most compatible and DVD compliant. You use the MPEG-2 video and the AC3 audio in your DVD authoring program to create the DVD formatted files.

If you want to do things the easier way, just use TMPGEnc for the audio, encoding the audio and video streams. You can set it to MPEG-1 Layer2 audio, which is compatible with most players. AC3 saves space, but Layer2 works fine and is a lot easier to deal with.

yup , I agree with you about using the TMPGenc audio thing...
I just wanted to be sure I wusnt losing quality on the audio, since it outputs *.mp2 files, not mp3...
And I also wanted to be sure cuz Ive been advised to use another app while I wus reading a guide on this site.

I think ill try the ac3 thing... If that dont work Ill just stick with tmpgenc mp2's... its souding good on my dvd...

FYI mp3 is not supported by dvd video standards. So if the final detination is dvd it will have to be pcm, ac3, or mp2 for audio. And most ntsc players accept mp2 only dvds, probably only the oldest first generation players might have problems with it. Other than that mp2 is just fine.

ok, now that Im sticking with the TMPGenc Audio....
On the Audio Settings Tab: u think that 48000 / Joint Stereo / 192 is enuff for a good qua. ?

If you want the best quality MP2 audio encodings, then you may want to use tooLame instead of TMPGEnc's built-in MP2 encoder...

Download tooLame and save it to a folder on your hard drive - a sub-folder within the TMPGEnc Program Files location would be ok.

Then within TMPGEnc's Environmental Settings go to the Audio Engine tab.
Under MPEG-1 Audio Layer II Encoder you'll see that TMPGEnc can use it's own built-in encoder or you can Browse to the location of tooLame and it'll use that instead.

It may be a purist thing - but as you're talking about encoing audio for a music video you may as well use the best tool for the job.

When deciding upon a bitrate for your new MP2 audio you should establish what the audio bitrate of the original source is - i'd use AVIcodec to do this.
If the original source is for example 160kb/s then there's little point in re-encoding to a higher bitrate as you can't gain any extra quality.
Maybe re-encode the audio to the same bitrate as the source?
