can i convert AVI with AC3 ro mpeg2 with AC3?

[wizzy]

how can it be done?
with TMPGEnc?

Why would you want to convert to video stream to MPEG2 and leave the audio in AC3? Even if you could multiplex them to a system stream (i.e. a video), no DVD player would ever play it. If you wan't to keep the 5.1 sound of your AC3, take a look at Hypercube's homepage. If it's only a 2 channel AC3 or you do not have a surround equipment, use Azid, BeSweet or HeadAC3 (which is kind of a GUI for Azid) to encode it to MP2, then mux video and audio (p.e. with TMpegEnc).

Wolleric, AC3 is the standard for DVD audio. You would want to retain it, as it is the only format for DVD that supports 5.1 surround sound. If the AC3 contains 5.1 sound, then you would want to retain this for your final DVD.

Wizzy, if the AC3 only contains 2 channel sound, then your probably better served just converting it to MP2, or PCM audio. You can determine this using FILE | FILE INFORMATION in VirtualDub after loading your AVI. It should report either 2 Channel, or 5 Channel under the audio information.

To extract the AC3 audio, open the AVI using VirtalDub. Under the AUDIO menu, select DIRECT STREAM COPY. From the FILE menu, select FILE | SAVE AS WAV

Name your file as a .AC3 file (example: EXTRACT.AC3 )

Use AC3FIX.EXE (see the TOOLS section to the left, or search google.com) to repair any bad frames in the file (trust me..it will have them). If you skip this step, you will have audio sync problems on your final DVD.

Encode your video to a video only M2V file (you can exclude the audio through the rest of the process, until the final step).

Download a copy of SpruceUp (google.com should get you a copy, and a key generator). Don't ask for a key generator here, as it's against the rules.

Make sure your M2V file, and your AC3 file have the same name, and they should both be in the same directoy. For example:

Harry Potter.M2V
Harry Potter.AC3

If you've done everything correctly, when you add your M2v to SpruceUp, it will import your AC3 audio as well. Make sure you 'simulate' before burning your DVD.

The final product will be a DVD, retaining the original AC3 audio.

thanks man ill try that

Sorry, when I read MPEG-2 I thought of SVCDs. But of course AC3 sound is possible on a DVD.
