BeSweet channel order

[senderj]

I am trying to use BeSweet to encode 6 mono wav into AC3, but not sure about the channel order in the mux file list. Here is my BeSweet command line:

"C:\AC3Machinev0.41\BeSweet\BeSweet.exe" -core( -input "D:\data\t3c2_t3c3.mux" -output "D:\data\t3c2_t3c3_6ch.ac3" -logfilea C:\AC3Machinev0.41\BeSweet.log ) -ota( -d 0 ) -ac3enc( -b 448 -6ch) -profile( The AC3Machine v0.4 )

And here is the content of my mux file list (all are mono 16bits signed wav produced by Goldwave from a 2ch stereo master):
d:\data\t3c2_t3c3_FL.wav
d:\data\t3c2_t3c3_FR.wav
d:\data\t3c2_t3c3_SL.wav
d:\data\t3c2_t3c3_SR.wav
d:\data\t3c2_t3c3_C.wav
d:\data\t3c2_t3c3_LFE.wav

My questions:
1. Is the channel order correct?
2. What is the difference between the above command line and this one:
"C:\AC3Machinev0.41\BeSweet\BeSweet.exe" -core( -input "D:\data\t3c2_t3c3.mux" -6chwav -output "D:\data\t3c2_t3c3_6chwav.ac3" -logfilea C:\AC3Machinev0.41\BeSweet.log ) -ota( -d 0 ) -ac3enc( -b 448 ) -profile( The AC3Machine v0.4 )
3. Not sure what bitrate to use in -ac3enc. I use 448 just to follow some posts in the forum. When I make 2ch AC3 for my DVD, my video is 7900 and audio 224. Should I adjust the video rate to allow higher audio rate for 6ch AC3?

Please help.

No...Read Q31 from BeSweet FAQ.

This one corresponds to a Stereo (2 channels) output file whereas the above command line refers to multichannel (6 channels).

384 or 448 kbps...It's more safer for 6ch.

Kurtnoise13,

Thanks for the reply.

Had read Q31 and Q31b but didn't know which one to follow. Will try Q31.

Then what is the -core(.... -6chwav ...) for? What if I use both, i.e. -core(... -6chwav ...) -ac3enc(.... -6ch ...)?

Thanks. Will use video 7552 and audio 448.

Yeah...Q31. This is the right order for an ac3 output file.

Ouups..I read too fast your command line. -6chwav produces an 5.1 Wav file. So, no ac3 output file. And, AFAIK you can't use these both command line. BeSweet will feed the first one.
