AC3 Delay setting in BeSweet

[oddball]

When you demux an AC3 stream in DVD2AVI it gives you a delay setting in the filename.AC3 that you can set in the delay setting of BeSweet.

What I would like to know is. If you go directly from the VOB files using BeSweet you do not know what the delay setting should be. Or does BeSweet calculate this for you just like DVD2AVI does when it demuxes?

-ota( -d auto ) will automaticly assert the delay.

Maybe a very stupid question, but I am a bit confused at the moment! :rolleyes:

Do I have to pay any attention to the delay value of the AC3 file, when I want to encode it to a MP3 or OGG Vorbis file? If yes, why?
When I have to? When I do not have to?

e.g. SLEEPERS AC3 T01 3_2ch 448Kbps DELAY -79ms.ac3

Possible command line...

"E:\Movies\MPEG-4\BeSweet 1.4 (Audio - Encoder)\BeSweet.exe" -core( -input "E:\Movies\temp\SLEEPERS AC3 T01 3_2ch 448Kbps DELAY -79ms.ac3" -output "E:\Movies\temp\SLEEPERS.ogg" -logfile "E:\Movies\temp\BeSweet.log" ) -azid( -c normal -g max -L -3db ) -ogg( -q 0.200 )

or...

"E:\Movies\MPEG-4\BeSweet 1.4 (Audio - Encoder)\BeSweet.exe" -core( -input "E:\Movies\temp\SLEEPERS AC3 T01 3_2ch 448Kbps DELAY -79ms.ac3" -output "E:\Movies\temp\SLEEPERS.ogg" -logfile "E:\Movies\temp\BeSweet.log" ) -azid( -c normal -g max -L -3db ) -ota( -d -79 ) -ogg( -q 0.200 )

In case of delay value of 0ms, I can stay with ...?
e.g.

"E:\Movies\MPEG-4\BeSweet 1.4 (Audio - Encoder)\BeSweet.exe" -core( -input "E:\Movies\temp\SLEEPERS AC3 T01 3_2ch 448Kbps DELAY 0ms.ac3" -output "E:\Movies\temp\SLEEPERS.ogg" -logfile "E:\Movies\temp\BeSweet.log" ) -azid( -c normal -g max -L -3db ) -lame( -p --alt-preset 128 )

or...

"E:\Movies\MPEG-4\BeSweet 1.4 (Audio - Encoder)\BeSweet.exe" -core( -input "E:\Movies\temp\SLEEPERS AC3 T01 3_2ch 448Kbps DELAY 0ms.ac3" -output "E:\Movies\temp\SLEEPERS.ogg" -logfile "E:\Movies\temp\BeSweet.log" ) -azid( -c normal -g max -L -3db ) -ogg( -q 0.200 )

Thank you very much in advance! :)

maybe q20 in here (http://forum.doom9.org/showthread.php?s=&threadid=15738) can answer your question..

[snowbeach]

If I was asking what q20 means, you were absolutely right! ;)
But I ask about setting the right delay value to a MP3 or OGG file (see my post again) - is it needed or not? :confused:
Thanks for your time!

BTW. What is the way to mux OGG and AVI files? Do I have to pay attention to something special? Never done this before? again a bit :confused: ;) But I think, maybe I have to take a look at http://www.doom9.org/ogg.htm !

@DSPguru
Got it! Of course, it is needed to set the right delay, in order to ensure a synch movie (muxing audio and video at the end)! Gonna mux OGG audio with OggMux! Sounds good! :D

One last question regarding the possible command lines, needed for my understanding! Just give me a YES or NO. Thank you very much in advance! ;)
