Convert MPEG2 movie with Mpeg audio to LPCM

[caulnguyen]

Hi,

I have an MPEG2 video/audio movie. I want to change just the audio part to LPCM, keep the video and re-create the movie. What's the flow to do that. I have TMPGENc Plus

thanks,

Cau

Are you planning on putting these files into a DVD authoring program? If so, you do not need to mulitplex them back together (unless the DVD program doesn't support that but I do not see a DVD program supporting PCM without seperate tracks).

You could load the MPG into TMPGEnc and then goto File, Output to File, Wave File.

To make sure I understand your help, I plan to do this.

Using TEMGEnc. Input: MPEG2 (video/audio), file => output to file => wavefile to extrace the Linear PCM

Using DVD Workshop to authorize. Select a replacement audio file => the wav file extracted from above which will replace the MPEG audio.

Is it correct?

thank you very much.

That sounds correct. I do not use DVD Workshop, but that sounds right.

When you're outputing the MP2 as a WAV you are converting it. Make sure it is 48000 Uncompressed. From what I see, that is the default setting in TMPGEnc.

It is interesting that by using LPCM audio, the final *.iso file is smaller than the one with MPEG audio. Does that make sense? I always have the impression that the compresses MPEG audio must be smaller.

thanks,
