Can You Make your own Dobly Digital on dvd?

[gotenks98]

Is this possible, is it worth the trouble?

[BJ_M]

it is possible yes ...

is it worth the trouble -- i think so ...

Maybe you need to understand (if you don't already) that Dolby Digital aka AC-3 can be 2.0 or 5.1

So most of us here like to make 2.0 AC-3 which is simply stereo or could be 2 channels but mono. Depending on the source it could even have regular Dolby Surround Sound.

But it is not multiple channel 5.1 AC-3

So just so you know it is easy enough to make 2.0 AC-3 but trying to make your own 5.1 AC-3 from a 2 channel stereo only source is a bit of a trick and probably not worth it.

I'm sure when BJ_M said that it was worth the trouble that he was talking 2.0 AC-3

yes and yes, and I am talking 5.1 (or at least 3.1)

do a search... you will have to spend some $$ or
experiment with little known buggy freeware.

[BJ_M]

for home stuff - i make a lot of 3.1 ... but 2ch is good for the least of just saving space ...

it will cost you lot more to make 5.1 than 2ch

i bet most people don't realize 'stereo' really means L C R , 3 channels ..

this is what stereo was when first introduced (in movie theaters) and only when a home version came out was it reduced to 2 channels ... to make it cheaper !

... to make it cheaper !

Cheap.. reminds me of mono "stereo" (monaural track with ambiance)
.. now that is what I call cheap!

[haloblack]

More importantly, does it go to 11?

More importantly, does it go to 11?

Only if it's in "Dubbly"! 8)

BTW what program(s) do you use to make 3.1 AC-3

Just curious

BJ_M, I've worked a fair share with audio, I've never heard the 3-channel thing, though I know the bandwidth allows for more than the two chosen audio channels, L and R. Any good reading materials you'd suggest on this?

I too, would like to know the software/process for 3.1 ... sounds interesting.

I produce all my dvd's using Dobly Digital 2.0.


I used to use a program called ACE Enc (comes with Scenarist) but now I use
My DVD Deluxe, it was 100 dollars and does excellent 2.0 channel dobly it will also encode the audio without touching the video.

Also DVDIt PE does AC-3 2 channel

I think that 5.1 channel dolby is redundent unless you are actually on a sound stage capable of recording 360 degree sound.

[BJ_M]

audio coding mode 3/0 (with or without LFE , so 3/0 or 3.1 ) ..

its a standard ac3 mode. LCR

for film with a lot of voice and such (this goes for motion picture also) , the best is mono panned across the screen in sync with the picture ...

surrounds - in SOME cases are more of a markerting hype than some thing that is truly nessessary --

action type films are where surround becomes importaint - though i can go into 50% ++ theaters and thier sound system is not properly set up -- even worse in some areas for the projectors ..

some early "stereo" history

1931 - Alan Dower Blumlein filed a patent application in Britain for stereo recording. in the patent - it is described as having 3 or 4 channels.

1933 - April 27 Stereoscopic sound was transmitted to the National Academy of Sciences and many invited guests at Constitution Hall, Washington. Transmission was over wire lines from the Academy of Music in Philadelphia and three channels were used with microphones respectively at left, center and right of the orchestra stage and loud speakers in similar positions in Constitution Hall. The orchestra in Philadelphia was conducted by Alexander Smallens while Dr. Stokowski in Washington manipulated the controls so as to enhance the music in accordance with his own views.


1940 - Harvey Fletcher and Stokowski made another stereophonic demonstration at Carnegie Hall April 9 and 10, with recorded stereo music from a three-channel system using sound on film with a frequency range of 30 to 15,000 cps and a volume range of 120 decibels. A 4th track was used as a loudness playback control track. The New York Times reported April 10 "Sound Waves 'Rock' Carnegie Hall As Enhanced Music' Is Played" and "The loudest sounds ever created crashed and echoed through venerable Carnegie Hall last night as a specially invited audience listened, spellbound, and at times not a little terrified."


NOTE --- notice the press notice above first describing loud (and it was loud!) music as 'rock' - bj_m

1953 - The Robe had 4-track stereo sound; was the first CinemaScope film and led the release of 33 stereo films in 1953, but stereo failed to transform motion picture soundtracks and would not reappear until 1975 with Dolby optical stereo sound. The Robe used directional sound, footsteps of Roman Legions marching from right to left, thunder and wind and rain of the crucifixion scene. The first time off-screen voices are actually heard off-screen, when voices warn Marcellus of his ship departure to Judea. Only Fox and Todd-AO would record dialogue with directional sound. All other studios provided some music in stereo for magnetic soundtracks, but recorded voices and sound effects in mono.

So in other words the 3.0 or 3.1 AC-3 encoding mode is a "standard" mode so either we have software that can do it or we don't.

I guess the question is this then ... is there any reasonably priced software that can do more than 2.0 AC-3 or do we need something more "full blown" like Vegas Video with the 5.1 Plug-in?

Does softencode do this? I have it, but never play with it. Yeah, being lazy, looking for the quick answer.

[BJ_M]

yes softencode (i think - its been a few years since i used it) , vegas, sonic ac3 encoder, surcode .... they all have this //


cheap solutions ? non that i'm aware of ..
