Problem with Dual Language VCD

[Roanstalker]

Hi. I have a dual language RM file that was converted from a VCD (Not by me. I just downloaded it) and I want to know if theres a way to make it so that only one audio is played? I can turn off one speaker but I want to watch it on TV so I want to put it into a DVD and theres no way to choose language. Thanks.

Converting from VCD to RM to DVD won't be pretty. Expect huge quality losses. Convert the RM to DVD format and demux the audio file after converting. Using Audacity (a free audio editor) you can remove one of the audio channels and leave a mono file with just the other channel. You can author the DVD now with just the mono audio you want.

If you had the original VCD, DVD players that support VCD format usually have an option where you can play only one channel. I'm just saying that as an FYI thing since you don't have the original VCD.

Thanks. But is there a way to deal with the second audio while its still RM file? That way I can upload it onto youtube as well since a lot of people wants to watch it and on youtube it plays both audio channels with no way to turn either off.

I have no idea at all how to fix this problem in an RM file or if such a fix is even possible in that format. You can fix it after you to convert to another format such as VCD or DVD though, but again, you'll lose quality doing the conversion. You might consider converting it to Divx. At a high enough bit rate you could keep quality loss to a minimum (try at least 1000 Kbps for this file) and you could conver the sound to WAV format. Demux the AVI with VirtualDub-Mod, fix the WAV audio to have only 1 channel, mux the new audio file into the AVI (do direct stream copy) and then upload this to YouTube. It's a lot of work and you'll have to do some research on how to use VirtualDub-Mod to do this, but it's possible.

If the RM file had 2 separate streams of audio muxed into the container, it is conceiveable that you could create a Graphedit filter graph that opens, demuxes, strips out wrong audio, remuxes and saves a new file...

But I've never heard of any RMs being multiple stream (or even being capable of multiple stream)>>jeez, I hate RM!<<

My guess is that you've got 1 stream of audio which is stereo/dual channel. 1 channel is one language (Left), 1 channel is another (Right).
You might be able to demux decode and save the audio separately, edit out the offending language in a good audio app, save the new audio, convert a copy to RM audio (mono this time, at ~the same bitrate as the original--but it's gonna sound bad).
Then you could mux the original video stream to the new audio stream, save that as a new RM file and then upload THAT to youtube. Boy, that's a lot of work, just to save 1 generation of video encoding...

Try RMMuxer to remove the second audio track.

[Roanstalker]

Yeh. Its one stream with right/left channels. Sounds like a lot of work. How do I extract the audio with RMMuxer? And what is a good audio editting program? Thanks.

How do I extract the audio with RMMuxer?

Have you looked at the program ? It has four buttons, and one of them is "Cancel". I'm sure you can work it out.

what is a good audio editting (sic) program?

From Jman98's post (above)

Using Audacity (a free audio editor) you can remove one of the audio channels and leave a mono file with just the other channel. You can author the DVD now with just the mono audio you want.

I'll try them. Thanks.
