Unterschied 12Bit und 16Bit (Sound)

12Bit and 16Bit difference (sound)



Frage von dertester:
März 2007

Hi,

I was wondering what the difference between 12-bit mode and 16-bit mode. I have looked for this reason, just the instructions of SonyDcr-Hc23E through and read as it stands: In a with 16-bit mode recorded tape dubbing is not possible.
But unfortunately there was nothing inside whether a dubbing later s.Pc possible. The default was a 12-bit mode. What are the advantages or disadvantages it has when I use the 12Bit or 16Bit?



Antwort von Schleichmichel:

What Wikipedia says about this?

In any case, you can afterwards s.PC nachvertonen until the doctor comes. Set it to 16Bit. The 12Bit feature is only available for a camcorder dubbing in thought, at the expense of bit depth.

When the bit Digibildern describes the brightness gradations in the audio dynamics.



Antwort von AndreasBloechl:

Caution but if you've already started to film with 12Bit. I had synonymous mitendrinn of 12 to 16 bit and s.diesem no premiere date has Timecode observed and I have two sections to capture. 16 bit is the best setting if you are with the PC after work or later in DD synonymous render like.





Antwort von Markus:

Otherwise save the camcorder manufacturers but synonymous all possible features and equipment features. Why not be the last audio recording opportunity with only 12-bit sampling rate? - That would be quite incidentally times even an improvement ...?! ;-)



Antwort von AndyZZ:

I use currently a SonyDCR-HC1000. The can with the optional 4-Channel Microphone Souuround as a kind of sound recording. Stereo and stereo to the front to the rear. These are the two stereo channels at the same time on the DV tape is written, but only in 12 bits. In Premiere Bastel me then that such a "kind" 5.1 sound. Certainly suffices only the lowest standards, but it is quite funny. If I was still busy with practice, then perhaps what is right out in manners. I would be the 12 bit mode already missing ...
And whether the difference in the sound actually heard, was synonymous times then asked ...

Okay, the lights me.

It depends of the recording and playback options, the personal claims and from the hearing. As for me, I hear a difference between 48 kHz and 32 kHz sampling rate. But it surprised me lately is no longer really ... ;-)



Antwort von Schleichmichel:

At the time, with the first 8-bit samplers, it was synonymous strange ... because one could so many sounds combine. With 16-bit later to the dynamics were different, so you had to edit a lot, sounds of nature to adapt.

Well, no preference. Toll would be the way, if the quality of the soundtrack in favor of a higher image quality may decrease. This could in HDV or AVCHD to a minimal improvement, if the soundtrack could be completely omitted and the space gained in the data for more image information is used. Instead, it draws on an external device.



Antwort von AndyZZ:

Well, amateur filmmakers who would like to come with an external device rumschleppen. Most already do that with an external Micro Tripod or heavy.



Antwort von Schleichmichel:

I think just as an option, that of a camcorder in the menu data from the Sound could settle down or just completely off. Who does not want it to remain flat.

I have quite often external sound, because my then Although a camcorder mic-in had, but no manual level was possible. That made the mic-in for me anyway superfluous. Because what I have of a possibility of better microphones to benefit, but these levels can not be taken?

Should not be Klugscheißer (and still is) my belongings very frightened when I (or you) have read. But is so obviously a prescription. (16! Bit only would be to improve and bitrate and sampling rate are different things.) Perhaps korrigierst du's? ;)

OnTopic:
I think is another argument for 16-bit recording the fact that the DVD standard 16-bit sound and thus provides a (lossy) bitrate conversion deleted. (If you have a target DVD medium has provided)

Lossy? If you look at the bit rate of 12 to 16 bit konvertierst, only empty bits appended.



Antwort von vdp1331:

Ok, that they are simply attached, I can not imagine at the moment but did not synonymous me the opportunity to better inform.
But you're right: it was semi-of me;) This ash on my head!

I think the 12-bit sound belongs to the DV specification and is already for compatibility reasons continued.
Why some Manufacturer camcorder with its "factory setting" 12 bit disconnected, I do not synonymous.

Stands in the magazine professional audio "from the March 2007 article" More bits, more sound. " According to the article will first empty bits appended only when editing a little store. So, normalization, etc.

Was perhaps misleading, but as I said: Surrender to 12 bit would be an improvement.

"vdp1331" wrote:

You're right, Vincent. Since I have a thought process is skipped. With DV are the specifications for the bitrate and the sampling rate so directly together. With 12 bit you get only 32 kHz sampling rate, while the 16 bit is better 48 kHz. That means in this case, from a conversion of the resulting bitrate necessarily synonymous to convert the sampling rate.

This is not completely true. As with the bitrate when converting DV video at the same time, a change in the sampling rate of consumption can actually hear the sound worse. In the worst case Musikinstumente sound after the conversion as totally different instruments (WERS ever heard of knows what I mean).

In an ordinary convert this problem does not occur.
