Infoseite // AC3 sound problems - DVDA - too quiet



Frage von JulianW:


Hi everyone,

s.verzweifeln so slow I am. The result is simple: with DVD-A DVD created is too low.

I very quickly found out that the AC3 Pro auto lowers by 31 db, and i select "off only" must. Here it gets complicated.

In Vegas (10.0) I render in mpeg2 format for DVD-A. Since the soundtrack is even indoors with ... However, since I can practically set anything, wsa somehow had to do with the db. Below is tuned a logo of Maine. Is that AC-3 Pro?

The plugin is available but apparently I can directly synonymous to create an AC3 file out of Vegas. This, however, I would find even complicated arg ... I do not want anything in the Architect must merge again.

In the DVD-A I can only synonymous with the sound very little set. And while in the settings, since I have the choice between PCM, AC3 or AC3 Stereo Surround. Here comes my first problem: is the same as AC3 stereo AC3-Pro? Everywhere it is said with AC3-Pro, I could turn this option "Lower Sound" ... for me it is not there.

In Architect, I have only three options when I compress new:
PCM
AC-3 Stereo
AC-3 Surround

That's it.

Even as icing on the cake: When I look at the rendered video of Vegas with the "originals" compare, then the sound is practically the same. Say: As does the volume. Does that mean the opposite conclusion: Vegas brings the sound right "out," Architect makes it so much quieter. And I can not find anywhere an option to prevent this.

Does anyone happen to experience?

Love, Julian!

Antwort von tommyb:

This is actually normal ... because it is just set to default. The fun is called Dialog Normalization.

If you look at once you purchase DVDs, where the level is not synonymous different - but there the language usually commutes. between-31dB and-27dB. Everything about it is then the range of sounds that are not compatible with neighbors (explosions, gunfire, screams).

If you sound your normal level, about to 0dB, then you work a little differently than is usual for DVD shoot. That's not bad, because if you know how all this nonsense works.

I'm assuming that you have anything that is louder than the language. In this case, you can proceed as normal. When the DVD sets later in the DVD player, then the volume on the same level as the dialogue volume at a purchase DVD.

You ignore, however, the dialog normalization option and force the soundtrack to 0dB-31dB instead - then your DVD after you insert the first volume of explosions in purchase DVDs.

Antwort von JulianW:

Well ... how shall I say? The problem I noticed is because I have the complete DVD set in the player and have only heard almost nothing.

Meaning: The end result is too low. How much has the whole DB is totally me, ultimately no preference ... But when I use the television close to 100% volume to have somewhat "normal" to hear then that's certainly not the intention, right? ;-)

Love, Julian!

Antwort von eXp:

What exactly are you doing anyway? Mix it because even a 5.1 Project or only stereo?

Which setting you use because in DVDA? If you spend your Project with MPEG-2 with Sound, are you then synonymous PCM, and AC3 stereo in a DVDA?

Antwort von MK:

The volume of the uncompressed input signal is played back through a Dolby decoder correctly set 1:1 in volume as the input signal when you dial the Dialog Normalization-31dB in the Dolby encoder.

Dynamic Range Compression you should have them in the encoder of synonymous (controls the playback behavior of the Dolby decoder in the Midnight mode).

Professionally, this is not, however. The Dialog Normalization is meant that every program sounds on every (properly adjusted) investment equally loud, because it is believed that the language is always in roughly equal proportion to the rest of the sounds and Music.

The correct value should be determined Dialnorm therefore advance s.einfachsten with the Dolby Media Meter of.

An incorrectly set Dialnorm value would otherwise lead to unsightly synonymous like to "pump" in the Sound if you use the additional metadata for dynamic range compression, as the correct Dialnorm value is used by the decoder as a "baseline" for the dynamic compression.

Hi MK,

yes there are always referred to SuMa forum visitors when they ask things that have been discussed many times.

In return, I find it but it is always synonymous shame when issues become inflated, so with a reference to the "professionalism" should be answered, yet not even read the post really.

Just this option, of which you speak, I'm looking for hours and can not find them.

Love, Julian!

Antwort von eXp:

But you could synonymous times to answer questions, eg. do you still do not know if your project is now in 5.1 or 2.0. For if it is only 2.0, so you need not the Dialog Normalization!

Synonymous therefore the question of what you have set in DVDA.
If you have not tried it yet, give the sound simply AC3-Pro as a stereo file out to jobs in the DVDA to AC-3 stereo and then drag on the soundtrack.

With me so far without any problems.

Otherwise, try it once with the AC-3 Studio encoder, so you should really nothing can go wrong.

Antwort von JulianW:

Hi exp

as I said:
I have found in DVDA only three possibilities I can choose the audio:

PCM Stereo
AC3 Stereo
AC3 Surround

My first problem is that I do not even know if now is the AC3-PRO or not. That is not so easy to find out if you do not know if there is a distinction between "normal" and "Pro".

In all three versions, I have the choice, there is nothing in the db-based set. Neither PCM nor in the two AC-3 variants.

It does not (yet) does not really matter what format the vorliert. I'm not s.die options ran, no preference what I do.

Love, Julian!

Antwort von eXp:

Which AC-3, it is now, "PRO" or "studio" is no preference, the difference in "Pro" is mainly the fact that you can manipulate all the parameters themselves. As just synonymous the dialogue normalization.

Otherwise, you can test the sound even as times as. Wav file (uncompressed PCM) and output set in DVDA synonymous PCM.

Antwort von JulianW:

Well, I post so extra at the Vegas forum and not in the authoring forum because it is probably quite software-specific.

Again, the question of what AC3 is it now that I've made. I do not know ... I only know that I have few options available and that no PRO behind it.

However, I just know, synonymous, that the DVDA usually the AC3 with PRO should be there. For me it is to say first of all: Find out if it is the PRO, or whether perhaps there is an installation problem.

Here is an info about this:
http://www.vegasforum.de/ac3-pro-encoder-t1067.html?t=1067

And yes ... that licenses are all valid I have entered extra-examined.



Love, Julian!

Antwort von MK:

MPEG-2 and AC3 render separately ... Then in Vegas are synonymous these options are available.

When you compress on DVDA to AC-3 (of PCM or non-compliant AC3) is always encoded with-27dB Dialnorm and on the other parameters can not influence.

Or if this is too complicated actually render PCM sound from Vegas and DVDA select a project setting PCM, then everything will remain 1:1, at the expense of higher data consumption in the soundtrack.

Dialnorm is synonymous relevant for 2.0 because it always keeping the total volume.

That I will not do that. I see no point inside ... what "replace" the synchronized sound and reinsynchronisieren later need? Why tear apart for seven or eight "film property", together with intro, outro, and so next menu, and everything to exactly twice as many individual pieces have to render?

Okay, we're getting closer, this is a more useful response. Say: If I directly "for DVDA" then I can render in DVDA not change what really s.Sound.

What is annoying ... But okay, so I must be living well. For the future, this means that "curb" in Vegas does not have the sound but rather have "s.Limit, right?

Love, Julian!

Antwort von MK:

Oh, and your sound is probably MPEG-2 audio ... at least in Vegas 9 is in the MPEG-2 presets for DVD AC3 sound are not included here. I would be surprised if synonymous here AC3 encoder of MainConcept encoder would be used as Sonyden of Dolby licensed. Therefore again: MPEG-2 video and AC3 audio render separately, holding times that it's not different.

Quote: Again, the question of what AC3 is it now that I've made.

And I've said that there is no preference. The DVDA, you can only AC-3 stereo set and AC-3 Surround. Whether you cut and paste is now AC-3 STUDIO PRO or no preference here. It is important that you choose NOT surround if your soundtrack is really only in stereo!

But let's experiment with PCM, should there, such as MK says, everything will remain 1:1.

That's just times that you set during authoring on elementary streams and not program streams which are in a Picture and sound file.

For this reason, you can set in that it synonymous DVDA audio - and video files with the same name are grouped inside the car pull.

At the synchronicity that does not synonymous, as you have even two equal length files.
