TNMPGenc and MP3 question

[simmons3d]

I am encoding a dual layer dvd to burn to dvd-r and have converted the audio to an mp3 file to save room and allow for increased video bitrate. (the program runs 3 hours) TNMPGenc seems to accept the audio file OK, but it doesn't estimate a smaller final filesize than with the wave file. The MP3 file is 225MB and the WAV was 1.9GB. Doesn't tnmpgenc see the reduced filesize of the mp3? I'm using 2.54 (it judges field order where newer versions don't) would a newer version see the audio for what it is?

If I just go ahead and encode for a 5.5GB file will it actually end up being 4GB?

Thanks!

you use the wizard don't you? it dosen't really matter what the imput size is. when you encode it you can adjust the file size to what ever you want and the wizard will tell you roughly what the output file size will be before you start the process.......

Ya, thats the weird part.... The wizard says the same final filesize with the MP3 (225MB) as it does with the WAV (1.9GB). I know the WAV calculation is right, so it must not look at the audio size, it must just go with a preset size depending on the length. I guess I'll just convert for 5.5GB and see what it does...

TmpGenc will convert your audio source (be it mp3 or wav) to mp2 audio. So the size of the input files doesn't matter, only the play length.

Hope this helps.

...cause mpeg audio 2 (not 1) is the standard for DVD compliant files.
And mp3 is mpeg audio 1 layer 3 (normally).
