Frustrated Audio Rip

[ss9168]

I am somehwat befuddled about how to achieve my end goal of taking an xvid file with ac3 audio and converting it to mp3.

The problem I am having is when I burn dvd's with xvid/ac3 they won't play on my philips player.

I can only assume that I need to convert the ac3 to mp3, rip out the ac3 audio from the video and then combine the video/mp3 stream into a new file. Am I nuts? How do you do this?

Thanks

Most likely, you can set your player to do AC3 audio from AVI (as Video DVD audio, all DVD players can)- there was a similar thread some week ago, and that was the solution.
Otherwise, it's not that hard - get the AC3 decoder and MP3 encoder for VirtualDub, load the AVI, set video to direct stream, audio to full processing and select and configure MP3, save AVI.

The problem that I am having is that when I burn the dvd-rom's (osX & toast 7) with ac3 audio the playback is all garbled. I don't have the same problem with mp3 audio. Sooooo.... my thought is strip out the ac3 entirely and repalce it with mp3.

When I have created a mp3 an added it to the file w/o removing the ac3 file it still doesn't work right.

No, not many AVI players handle multiple audio tracks anyway, so you have to replace the audio stream, not add another. Since you seem to be on Mac, I'm not the one to tell you how that's done...

I should have been clearer, sorry. I am using a PC to do all of the video work. I am just burning the dvd on a mac.

[mats.hogberg]

OK, so then, the VirtualDub way should work. Both the lame and ac3 filters are found under tools.

Is it possible that the video is pal and just not playing correct?

[mats.hogberg]

Probably not, since that doesn't manifest itself as garbled audio...

Would PAL -> NTSC show itself as a bad burn where the video skips around and maybe only shows half screen? That is really what is happening after the burn. ALthough it still looks fine on my computer

[mats.hogberg]

No, but your player wouldn't play at all, or play in B/W or with a rolling picture. (And possibly cut off in the lower half.) A computer is unaware of PAL/NTSC issues, so both would play equally well.

Would it help to try a known good vid & audio? Same format but test clip.

[ss9168]

Interesting reply post. The bottom half of the video does disappear and the video jumps around (time wise).

It sounds like I have a PAL video I need to convert. How would one do that?

[mats.hogberg]

Search. It's been asked (and replied to) many, many times.

ss9168 - why don't you download Gspot and see if your video is "PAL like" - 25 fps. I don't know what player you have since you just say "Philips", but if you have the DVP-642, it WILL play PAL just fine. If you have this player, try looking in setup and be sure that you set your video output to NTSC and not something like "auto". It could be that your source video is PAL and your video output is "auto", which means the player sends exactly the same video on output as it gets in input. PAL in, PAL out. You need to force the output to NTSC.
