Keeping the Surround sound when converting to DivX

[martmanr]

Is there any way of keeping the surround sound when converting to generic (DivX)? CloneDVD mobile seems to always convert the DVD to stereo.

this mod to devices.ini will copy the sound track from the dvd so if its AC3 it will be an avi with AC3 soundtrack

[DivX with orignal sound]

Thanks!
I'll give it a go tonight and let you know how I get along.

@martmanr,

I just ran a quick test without any customizations to the Devices.ini file. I used an avi file I created with CloneDVD Mobile. When coverting from DVD to avi I checked the radio button for English Dolby AC-3/6 radio button which you will find under Audio and Subtitle Settings page under Title [n] stream configuration | Audio Streams. Actually it defaults to this radio button.

I copied the finished avi file on to a blank DVD as a data disk. I dropped it in my DivX compatible DVD player, a Panasonic DVD-S53, and I got full PCM 5.1 surround.

So I don't think you need to use a custom Devices.ini file. Can you give more information about why you don't think you are getting surround sound?

Hello KnoWei,

Thanks for your reply. I convert the files to AVI as you describe and when I play them on my philips dvp-5982 through a usb drive they play back in stereo. If I look at the properties of the file it says the audio is MPEG-Layer 3. If I modify the device.ini file like how this thread tells you too http://forum.slysoft.com/showthread.php?t=11381
the audio is AC3 and the surround sound works. So the good news is that I'm getting the results I'm looking for. I just don't understand why I'm not getting surround sound w/o modifying the device.ini...

Cheers,
Martmanr

@martmanr,

Can you tell me which .ini mod you are looking at from the other thread? I scanned them quickly and nothing jumped out at me. I'd like to compare it to my generic divx profile. Thanks.

KnoWei,
It is the Direct Sound Copy (For DTS/DD+) mod.
Cheers,
Martmanr

[eddweb]

yes that will work as well
both the one in this thread (that i put in) and the one maked up "direct sound copy)

the main difrance is:
moac=copy
and the removal of the lameopts section of mopts
removal of ARate=48000 as not reencodeing audio
removal of ABRate=128 as not reencodeing audio
removal of MVolume=10 as not reencodeing audio

my mod:

[* Generic (DivX) orignal audio]
Res1=320x240
Res2=480x360
Res3=640x480
Res4=720x540
ResAna1=320x180
ResAna2=480x270
ResAna3=640x360
ResAna4=720x404
ResAna5=852x480
AllowNativeTVResolution=1
VTag=DIVX
mopts=-audio-preload 0.8 -delay 0.1
lavcopts=vcodec=mpeg4
moac=copy
Format=avi -noodml
FileType=avi
Quality=23
useMencoder=1
SubTitle=1
MaxVBitrate=3000

orignal:

[* Generic (DivX)]
Res1=320x240
Res2=480x360
Res3=640x480
Res4=720x540
ResAna1=320x180
ResAna2=480x270
ResAna3=640x360
ResAna4=720x404
ResAna5=852x480
AllowNativeTVResolution=1
VTag=DIVX
mopts=-audio-preload 0.8 -delay 0.1 -lameopts br=%abrate%
lavcopts=vcodec=mpeg4
moac=mp3lame
Format=avi -noodml
FileType=avi
ARate=48000
ABRate=128
MVolume=10
Quality=23
useMencoder=1
SubTitle=1
MaxVBitrate=3000

this will use what ever the audio feed is you select on the audio selection DTS/AC3/PCM - it just copys the audio track

Thanks for this eddweb.

I'm going to have to experiment a bit. I'm 99.9% sure that using the Generic DivX that my DivX compatable DVD player played a clip from a data file on a DVD-R in surround. So it's interesting that martmanr did not get surround sound when playing a data file from a USB drive on his DVD player. I'll put his on my list of things that make me say "hmmm".

I can't say for sure when I'll test it but your settings definitely have got me curious.

Well, it would depend on the sound system as well. Mine will take any stereo 2 channel input and convert it to surround sound unless I set it to "direct" input in which case a stereo input will give me stereo output.

The audio copy option from eddwebb/lostinlodos makes a huge DivX file but if you are using the output for a DivX player linked to a DTS/DD sound system (and a screen!!) it is well worth it. For a handheld player it is rather pointless.

Here you go!!
