Trying to convert to divx5...

[Fmazzanti]

Hi folks,

I guess I could use some of your experience with this one. I have several streams of video+audio in the following format as reported by medianinfo:

File size : 346 MB
Format : Ogg media stream
Overal bitrate : 1160 KBps
Title : 13 - Cinetico
PlayTime : 41mn 43s 560ms

Video #0
Codec : DivX 5
Bit rate : 1068 KBps
Width : 560
Height : 420
Aspect ratio : 4/3
Frame rate : 25.000
Bits/(Pixel*Frame) : 0.182

Audio #0
Codec : Vorbis
Bit rate : 80 KBps
Channels : 2
Sampling rate : 44 KHz
Language : Spanish
LWING_GAIN : 01.00

which I'd like to play in my desktop dvd player which is divx5 compatible. I butn it into a CD and the player rejects it, mostly because this is not purely divx5 but has this damn vorbis codec. I then decided to convert it into standard divx5 using virtualdub. As the video is already divx5 I thought I only had to convert the audio, which can be done in virtualdub. There I loaded the .avi stream, told virtualdub to 'direct stream copy' the video and to 'full process' the audio, trying to convert it to mp3 using the LAME codec.
Well depending on the file I may either get something which is about 10Gb large, or something small but with audio synch problems.
I have no expertise in this field so I'm somewhat at lost, but I'm sure somebody here has dealt with this type f conversions... any good idea on how to proceed?

best regards and thanks,

Ferran.

What about de-muxing audio, converting, muxing new audio?

[Fmazzanti]

Well, if there is no other solution... I have quite a lot of these videos and going the demux-convert-mux_again route is big pain in the b*tt if this has to be done for every file. I have succesfully done this with one file in VirtualdubMod. Now the only thing I must learn is how to do a batch process so that I can feed several of these files to VirtualdubMod and he does automatically the demux-convert-mux game for me, with all the files in the list. Do you know how to do this?
Best regards.

I think it might be worth a try posting this also in the audio encoding section of the forum, where there are more folks who deal with vorbis I think. I know Sonic Foundry (now Sony) has a batch processing utility, but that won't do anything about automating the demux/mux cycle. You could also post in the Avisynth section -- they might give you a script, or ideas for a script to convert the audio in one step instead of 3.

Point: I assume you're trying to use an AVI container, and your files are currently in OGM. Vorbis audio is not supported in the AVI container, they must be converted to use in AVI.

VirtualDubMod can do what you're looking to do, you just need to use one additional command before saving your AVI: Video....Direct Stream Copy. Then your files won't be 10GB. For more, see http://www.doom9.org/vdubmod-procedures.htm and http://www.doom9.org/virtualdub_procedures.htm

Yes thanks... as I said before I've managed to do that within VirtualdubMod, the same you suggest. The way I do things is: Video->Direct Stream copy while I demux the audio converting it to mp3. Then I disable the original audio and mux the new (mp3) one and voila... job done. The problem is that I must do all this by hand, while I know there are procedures to automate this process.
Anybody around could tell me how to generate a script or something similar that can do this with a bunch of files at once, that is, without external intervention?
Best regards and thanks.
