I was doing the conversion steps by hand until I found AVI2DVD - it's a great time saver and the results are usually great.
There is a problem I have though - when I convert an AVI with 2 channel sound the resulting DVD has 5.1 AC3 sound. Is this a problem with my installation, or is there a setting I'm missing somewhere.
Using 5.1 for what was originally stereo spoils the result as the sound does not get processed for Dolby Pro Logic information by the amplifier.
It would also be nice to have a way to keep the original soundtrack if it is already AC3.
Any chance of releasing the source code so I can change it myself
hmmmm...well im not that technicaly saavy but i know virtdub allows u to save the the audio seperate from the video and just render the video, dont know if that will work for u. http://virtualdub.sourceforge.net/
there is also avidemux that demuxes the audio and video to seperate files, i believe that avidemux supports ac3. u can find that program here http://avidemux.sourceforge.net/ and scoll down to ur os.[/url]
I only drink when i'm alone or with someone else.
If we are what we eat then im fast, easy and cheap!
Indeed it is possible to do it maually but the step of replacing the 5.1 audio with the 2.0 version is quite tedious since the only way I have found to do it is by demuxing the AVI, converting the audio to 2channel AC3 if necessary, demuxing the vobs, remuxing to an mpg file and then reauthoring with DVDAuthor - exactly the steps that AVI2DVD is doing!
So it would be much nicer if AVI2DVD could be persuaded to keep the 2 channel format!
The conversion to 5.1 seems to happen when 'azid' is used - I think this is when AC3 is transcoded to 48k samples/sec. 'azid' defaults to 5.1 output but there is an option for stereo output. It is;
-s stereo
So you would need to add something like
-azid( -s stereo )
when transcoding 2channel AC3 to AC3.
The result of the MP3 to AC3 conversion is a 2 channel file so nothing needs to be done there.
It would be very useful to take the besweet commands from an ini file. Then they could be tweaked more easily by the adventurous - eg. I find many AVI audio tracks are much too quiet so I like to normalize them, or even compress them a little.
I patched the AVI2DVD executable to start a .cmd file instead of the besweet .exe file and appended the azid command to the parameters. This still resulted in 5.1 output.
Seems the -azid command has to come BEFORE the -ac3enc command.
Then it seems to work!
So when you next make some changes perhaps you could consider adding the 2.0 output option.
